------------------------------------------------------------------- Tue Nov 19 19:07:38 UTC 2024 - Dirk Müller <dmueller@suse.com> - relax pythran requirement ------------------------------------------------------------------- Fri Sep 6 18:26:08 UTC 2024 - Ben Greiner <code@bnavigator.de> - Add scipy-pybind11-2.13.patch gh#scipy/scipy#21199 - Rename 21063.patch to scipy-pr21063-gcc14.patch ------------------------------------------------------------------- Sat Aug 31 08:54:54 UTC 2024 - Ben Greiner <code@bnavigator.de> - Update to SciPy 1.14.1 * Add support for Python 3.13 * Bug-fix release with no new features compared to 1.14.0. ------------------------------------------------------------------- Thu Jul 11 17:55:47 UTC 2024 - Ben Greiner <code@bnavigator.de> - Fix hpc build: Provide f2py with correct shebang for build-time ------------------------------------------------------------------- Mon Jul 1 13:35:29 UTC 2024 - John Paul Adrian Glaubitz <adrian.glaubitz@suse.com> - Update to 1.14.0 ## Highlights of this release * SciPy now supports the new Accelerate library introduced in macOS 13.3, and has wheels built against Accelerate for macOS >=14 resulting in significant performance improvements for many linear algebra operations. * A new method, ``cobyqa``, has been added to `scipy.optimize.minimize` - this is an interface for COBYQA (Constrained Optimization BY Quadratic Approximations), a derivative-free optimization solver, designed to supersede COBYLA, developed by the Department of Applied Mathematics, The Hong Kong Polytechnic University. * `scipy.sparse.linalg.spsolve_triangular` is now more than an order of magnitude faster in many cases. ## New features # `scipy.fft` improvements * A new function, `scipy.fft.prev_fast_len`, has been added. This function finds the largest composite of FFT radices that is less than the target length. It is useful for discarding a minimal number of samples before FFT. #`scipy.io` improvements * ``wavfile`` now supports reading and writing of ``wav`` files in the RF64 format, allowing files greater than 4 GB in size to be handled. #`scipy.constants` improvements * Experimental support for the array API standard has been added. #`scipy.interpolate` improvements * `scipy.interpolate.Akima1DInterpolator` now supports extrapolation via the ``extrapolate`` argument. #`scipy.optimize` improvements * `scipy.optimize.HessianUpdateStrategy` now also accepts square arrays for ``init_scale``. * A new method, ``cobyqa``, has been added to `scipy.optimize.minimize` - this is an interface for COBYQA (Constrained Optimization BY Quadratic Approximations), a derivative-free optimization solver, designed to supersede COBYLA, developed by the Department of Applied Mathematics, The Hong Kong Polytechnic University. * There are some performance improvements in `scipy.optimize.differential_evolution`. * `scipy.optimize.approx_fprime` now has linear space complexity. #`scipy.signal` improvements * `scipy.signal.minimum_phase` has a new argument ``half``, allowing the provision of a filter of the same length as the linear-phase FIR filter coefficients and with the same magnitude spectrum. #`scipy.sparse` improvements * Sparse arrays now support 1D shapes in COO, DOK and CSR formats. These are all the formats we currently intend to support 1D shapes. Other sparse array formats raise an exception for 1D input. * Sparse array methods min/nanmin/argmin and max analogs now return 1D arrays. Results are still COO format sparse arrays for min/nanmin and dense ``np.ndarray`` for argmin. * Sparse matrix and array objects improve their ``repr`` and ``str`` output. * A special case has been added to handle multiplying a ``dia_array`` by a scalar, which avoids a potentially costly conversion to CSR format. * `scipy.sparse.csgraph.yen` has been added, allowing usage of Yen's K-Shortest Paths algorithm on a directed on undirected graph. * Addition between DIA-format sparse arrays and matrices is now faster. * `scipy.sparse.linalg.spsolve_triangular` is now more than an order of magnitude faster in many cases. #`scipy.spatial` improvements * ``Rotation`` supports an alternative "scalar-first" convention of quaternion component ordering. It is available via the keyword argument ``scalar_first`` of ``from_quat`` and ``as_quat`` methods. * Some minor performance improvements for inverting of ``Rotation`` objects. #`scipy.special` improvements * Added `scipy.special.log_wright_bessel`, for calculation of the logarithm of Wright's Bessel function. * The relative error in `scipy.special.hyp2f1` calculations has improved substantially. * Improved behavior of ``boxcox``, ``inv_boxcox``, ``boxcox1p``, and ``inv_boxcox1p`` by preventing premature overflow. #`scipy.stats` improvements * A new function `scipy.stats.power` can be used for simulating the power of a hypothesis test with respect to a specified alternative. * The Irwin-Hall (AKA Uniform Sum) distribution has been added as `scipy.stats.irwinhall`. * Exact p-value calculations of `scipy.stats.mannwhitneyu` are much faster and use less memory. * `scipy.stats.pearsonr` now accepts n-D arrays and computes the statistic along a specified ``axis``. * `scipy.stats.kstat`, `scipy.stats.kstatvar`, and `scipy.stats.bartlett` are faster at performing calculations along an axis of a large n-D array. ## Array API Standard Support * Experimental* support for array libraries other than NumPy has been added to existing sub-packages in recent versions of SciPy. Please consider testing these features by setting an environment variable ``SCIPY_ARRAY_API=1`` and providing PyTorch, JAX, or CuPy arrays as array arguments. * As of 1.14.0, there is support for * `scipy.cluster` * `scipy.fft` * `scipy.constants` * `scipy.special`: (select functions) * `scipy.special.log_ndtr` * `scipy.special.ndtr` * `scipy.special.ndtri` * `scipy.special.erf` * `scipy.special.erfc` * `scipy.special.i0` * `scipy.special.i0e` * `scipy.special.i1` * `scipy.special.i1e` * `scipy.special.gammaln` * `scipy.special.gammainc` * `scipy.special.gammaincc` * `scipy.special.logit` * `scipy.special.expit` * `scipy.special.entr` * `scipy.special.rel_entr` * `scipy.special.xlogy` * `scipy.special.chdtrc` * `scipy.stats`: (select functions) * `scipy.stats.describe` * `scipy.stats.moment` * `scipy.stats.skew` * `scipy.stats.kurtosis` * `scipy.stats.kstat` * `scipy.stats.kstatvar` * `scipy.stats.circmean` * `scipy.stats.circvar` * `scipy.stats.circstd` * `scipy.stats.entropy` * `scipy.stats.variation` * `scipy.stats.sem` * `scipy.stats.ttest_1samp` * `scipy.stats.pearsonr` * `scipy.stats.chisquare` * `scipy.stats.skewtest` * `scipy.stats.kurtosistest` * `scipy.stats.normaltest` * `scipy.stats.jarque_bera` * `scipy.stats.bartlett` * `scipy.stats.power_divergence` * `scipy.stats.monte_carlo_test` ## Deprecated features * `scipy.stats.gstd`, `scipy.stats.chisquare`, and `scipy.stats.power_divergence` have deprecated support for masked array input. * `scipy.stats.linregress` has deprecated support for specifying both samples in one argument; ``x`` and ``y`` are to be provided as separate arguments. * The ``conjtransp`` method for `scipy.sparse.dok_array` and `scipy.sparse.dok_matrix` has been deprecated and will be removed in SciPy 1.16.0. * The option ``quadrature="trapz"`` in `scipy.integrate.quad_vec` has been deprecated in favour of ``quadrature="trapezoid"`` and will be removed in SciPy 1.16.0. * ``scipy.special.{comb,perm}`` have deprecated support for use of ``exact=True`` in conjunction with non-integral ``N`` and/or ``k``. ## Backwards incompatible changes * Many `scipy.stats` functions now produce a standardized warning message when an input sample is too small (e.g. zero size). Previously, these functions may have raised an error, emitted one or more less informative warnings, or emitted no warnings. In most cases, returned results are unchanged; in almost all cases the correct result is ``NaN``. ## Expired deprecations There is an ongoing effort to follow through on long-standing deprecations. The following previously deprecated features are affected: * Several previously deprecated methods for sparse arrays were removed: ``asfptype``, ``getrow``, ``getcol``, ``get_shape``, ``getmaxprint``, ``set_shape``, ``getnnz``, and ``getformat``. Additionally, the ``.A`` and ``.H`` attributes were removed. * ``scipy.integrate.{simps,trapz,cumtrapz}`` have been removed in favour of ``simpson``, ``trapezoid``, and ``cumulative_trapezoid``. * The ``tol`` argument of ``scipy.sparse.linalg.{bcg,bicstab,cg,cgs,gcrotmk, mres,lgmres,minres,qmr,tfqmr}`` has been removed in favour of ``rtol``. Furthermore, the default value of ``atol`` for these functions has changed to ``0.0``. * The ``restrt`` argument of `scipy.sparse.linalg.gmres` has been removed in favour of ``restart``. * The ``initial_lexsort`` argument of `scipy.stats.kendalltau` has been removed. * The ``cond`` and ``rcond`` arguments of `scipy.linalg.pinv` have been removed. * The ``even`` argument of `scipy.integrate.simpson` has been removed. * The ``turbo`` and ``eigvals`` arguments from ``scipy.linalg.{eigh,eigvalsh}`` have been removed. * The ``legacy`` argument of `scipy.special.comb` has been removed. * The ``hz``/``nyq`` argument of ``signal.{firls, firwin, firwin2, remez}`` has been removed. * Objects that weren't part of the public interface but were accessible through deprecated submodules have been removed. * ``float128``, ``float96``, and object arrays now raise an error in `scipy.signal.medfilt` and `scipy.signal.order_filter`. * ``scipy.interpolate.interp2d`` has been replaced by an empty stub (to be removed completely in the future). * Coinciding with changes to function signatures (e.g. removal of a deprecated keyword), we had deprecated positional use of keyword arguments for the affected functions, which will now raise an error. Affected functions are: * ``sparse.linalg.{bicg, bicgstab, cg, cgs, gcrotmk, gmres, lgmres, minres, qmr, tfqmr}`` * ``stats.kendalltau`` * ``linalg.pinv`` * ``integrate.simpson`` * ``linalg.{eigh,eigvalsh}`` * ``special.comb`` * ``signal.{firls, firwin, firwin2, remez}`` ## Other changes * SciPy now uses C17 as the C standard to build with, instead of C99. The C++ standard remains C++17. * macOS Accelerate, which got a major upgrade in macOS 13.3, is now supported. This results in significant performance improvements for linear algebra operations, as well as smaller binary wheels. * Cross-compilation should be smoother and QEMU or similar is no longer needed to run the cross interpreter. * Experimental array API support for the JAX backend has been added to several parts of SciPy. - Cherry-pick upstream patch to fix build with GCC 14 * https://github.com/scipy/scipy/pull/21063.patch - Update BuildRequires from pyproject.toml ------------------------------------------------------------------- Sun May 26 11:26:14 UTC 2024 - Ben Greiner <code@bnavigator.de> - Update to 1.13.1 * SciPy 1.13.1 is a bug-fix release with no new features compared to 1.13.0. ## Issues closed * BUG: `scipy.ndimage.value_indices` returns empty dict for `intc`/`uintc` dtype on Windows * BUG: csr_array can no longer be initialized with 1D array * BUG: `TestEig.test_falker` fails on windows + MKL as well as… * BUG: Cannot find `OpenBLAS` on Cygwin * BUG: special.spherical_in: derivative at `z=0, n=1` incorrect * BUG: `eigh` fails for size 1 array with driver=evd * BUG: warning from `optimize.least_squares` for astropy with… * BUG: spatial: error in `Rotation.align_vectors()` with an infinite… * BUG: scipy.special.factorial2 doesn’t handle `uint32` dtypes * BUG: scipy.stats.wilcoxon in 1.13 fails on 2D array with nan… * BUG: scipy.spatial.Delaunay, scipy.interpolate.LinearNDInterpolator… * BUG: stats.yulesimon: incorrect kurtosis values * BUG: incorrect origin tuple handling in ndimage `minimum_filter`… * BUG: spatial: `Rotation.align_vectors()` incorrect for anti-parallel… * BUG: sparse matrix creation in 1.13 with indices not summing… * BUG: stats.zipf: incorrect pmf values - Allow pythran 0.16: Upstream's pre-emptive pin is not necessary - Drop scipy-pr20530-f2py_error.patch ------------------------------------------------------------------- Sun May 12 16:37:45 UTC 2024 - Sarah Kriesch <sarah.kriesch@opensuse.org> - Enable python-scipy:gnu-hpc for s390x (together with python-numpy:gnu-hpc) ------------------------------------------------------------------- Thu May 9 10:33:32 UTC 2024 - Sarah Kriesch <sarah.kriesch@opensuse.org> - Enable openblas for s390x ------------------------------------------------------------------- Wed Apr 24 11:41:51 UTC 2024 - Ben Greiner <code@bnavigator.de> - Skip another test out of numeric precision for 32-bit - Fix HPC _version ------------------------------------------------------------------- Fri Apr 19 10:55:20 UTC 2024 - Ben Greiner <code@bnavigator.de> - Update to 1.13.0 ## Highlights of this release * Support for NumPy 2.0.0. * Interactive examples have been added to the documentation, allowing users to run the examples locally on embedded Jupyterlite notebooks in their browser. * Preliminary 1D array support for the COO and DOK sparse formats. * Several scipy.stats functions have gained support for additional axis, nan_policy, and keepdims arguments. scipy.stats also has several performance and accuracy improvements. ## New features * scipy.integrate improvements * scipy.io improvements * scipy.interpolate improvements * scipy.signal improvements * scipy.sparse improvements * scipy.spatial improvements * scipy.special improvements * scipy.stats improvements ## Deprecated features * Complex dtypes in PchipInterpolator and Akima1DInterpolator have been deprecated and will raise an error in SciPy 1.15.0. If you are trying to use the real components of the passed array, use np.real on y. ## Other changes * The second argument of scipy.stats.moment has been renamed to order while maintaining backward compatibility. - Release 1.12.0 ## Highlights of this release * Experimental support for the array API standard has been added to part of scipy.special, and to all of scipy.fft and scipy.cluster. There are likely to be bugs and early feedback for usage with CuPy arrays, PyTorch tensors, and other array API compatible libraries is appreciated. Use the SCIPY_ARRAY_API environment variable for testing. * A new class, ShortTimeFFT, provides a more versatile implementation of the short-time Fourier transform (STFT), its inverse (ISTFT) as well as the (cross-) spectrogram. It utilizes an improved algorithm for calculating the ISTFT. * Several new constructors have been added for sparse arrays, and many operations now additionally support sparse arrays, further facilitating the migration from sparse matrices. * A large portion of the scipy.stats API now has improved support for handling NaN values, masked arrays, and more fine-grained shape-handling. The accuracy and performance of a number of stats methods have been improved, and a number of new statistical tests and distributions have been added. ## New features * scipy.cluster improvements * scipy.fft improvements * scipy.integrate improvements * scipy.interpolate improvements * scipy.linalg improvements * scipy.ndimage improvements * scipy.optimize improvements * scipy.signal improvements * scipy.sparse improvements * scipy.spatial improvements * scipy.special improvements * scipy.stats improvements ## Deprecated features * Error messages have been made clearer for objects that don’t exist in the public namespace and warnings sharpened for private attributes that are not supposed to be imported at all. * scipy.signal.cmplx_sort has been deprecated and will be removed in SciPy 1.15. A replacement you can use is provided in the deprecation message. * Values the argument initial of scipy.integrate.cumulative_trapezoid other than 0 and None are now deprecated. * scipy.stats.rvs_ratio_uniforms is deprecated in favour of scipy.stats.sampling.RatioUniforms * scipy.integrate.quadrature and scipy.integrate.romberg have been deprecated due to accuracy issues and interface shortcomings. They will be removed in SciPy 1.15. Please use scipy.integrate.quad instead. * Coinciding with upcoming changes to function signatures (e.g. removal of a deprecated keyword), we are deprecating positional use of keyword arguments for the affected functions, which will raise an error starting with SciPy 1.14. In some cases, this has delayed the originally announced removal date, to give time to respond to the second part of the deprecation. Affected functions are: - linalg.{eigh, eigvalsh, pinv} - integrate.simpson - signal.{firls, firwin, firwin2, remez} - sparse.linalg.{bicg, bicgstab, cg, cgs, gcrotmk, gmres, lgmres, minres, qmr, tfqmr} - special.comb - stats.kendalltau * All wavelet functions have been deprecated, as PyWavelets provides suitable implementations; affected functions are: signal.{daub, qmf, cascade, morlet, morlet2, ricker, cwt} * scipy.integrate.trapz, scipy.integrate.cumtrapz, and scipy.integrate.simps have been deprecated in favour of scipy.integrate.trapezoid, scipy.integrate.cumulative_trapezoid, and scipy.integrate.simpson respectively and will be removed in SciPy 1.14. * The tol argument of scipy.sparse.linalg.{bcg,bicstab,cg,cgs,gcrotmk,gmres,lgmres, minres,qmr,tfqmr} is now deprecated in favour of rtol and will be removed in SciPy 1.14. Furthermore, the default value of atol for these functions is due to change to 0.0 in SciPy 1.14. ## Expired Deprecations * There is an ongoing effort to follow through on long-standing deprecations. The following previously deprecated features are affected: * The centered keyword of scipy.stats.qmc.LatinHypercube has been removed. Use scrambled=False instead of centered=True. * scipy.stats.binom_test has been removed in favour of scipy.stats.binomtest. * In scipy.stats.iqr, the use of scale='raw' has been removed in favour of scale=1. * Functions from NumPy’s main namespace which were exposed in SciPy’s main namespace, such as numpy.histogram exposed by scipy.histogram, have been removed from SciPy’s main namespace. Please use the functions directly from numpy. ## Other changes * The arguments used to compile and link SciPy are now available via show_config. - Drop 8c96a1f742335bca283aae418763aaba62c03378.patch (merged upstream) - Add scipy-pr20530-f2py_error.patch gh#scipy/scipy#20530, used to find workaround for failing HPC build gh#scipy/scipy#20535 ------------------------------------------------------------------- Tue Feb 27 17:20:08 UTC 2024 - Egbert Eich <eich@suse.com> - Add 8c96a1f742335bca283aae418763aaba62c03378.patch to fix issues with OpenBLAS 0.3.26 and later (boo#1220163). ------------------------------------------------------------------- Mon Jan 22 12:20:49 UTC 2024 - Daniel Garcia <daniel.garcia@suse.com> - Disable broken tests in s390x, gh#scipy/scipy#18878, bsc#1218608 ------------------------------------------------------------------- Tue Nov 21 04:25:02 UTC 2023 - Steve Kowalik <steven.kowalik@suse.com> - Update to 1.11.4: * MAINT: ensure cobyla objective returns scalar * MAINT: fixup dep warning * BUG: interpolate: fix spalde with len(c) < len(t) * BUG: pass unused xrtol in fmin_bfgs to _minimize_bfgs * BUG: Regression test for lsq trf boundary error * BUG: lsq trf gives x=1e-10 if x0 is near a bound * BUG: make Bessel-roots function not hang and not skip roots * io/matlab: Fix loading of mat files containing fn handles when simplify_cells=True * BUG: make L-BFGS-B work with single precision gradient * MAINT: stats: fix NumPy DeprecationWarnings * BUG: sparse.linalg: Cast to intc before SuperLU * MAINT: Use deb_system scheme to match meson's path inference & fix aarch64 * BUG: Fix python3.12 distutils dev.py build * BUG: stats: remove use of `BOOST_MATH_DECLARE_SPECIAL_FUNCTIONS` * MAINT: fix libquadmath licence * MAINT: newton, make sure x0 is an inexact type * MAINT: stats.CovViaEigendecomposition: fix _colorize for singular covariance * TST: fix `TestODR.test_implicit` test failure with tolerance bump * BUG: signal: freqz rfft grid fix * BUG: Support sparse arrays in scipy.sparse.csgraph.laplacian * MAINT: signal: Remove the cval parameter from the private function _pad_test. * BLD: Avoid absolute pathnames in .pyx files * BUG: Add back make_strictly_feasible to lsq trf. * MAINT: should not be using np.float64() on arrays * BUG: trust-constr Bounds exclusive * BUG: sparse.csgraph: Support int64 indices in traversal.pyx * BUG: add infeasibility checks to min_weight_full_bipartite_matching * DOC, MAINT: workaround for py311 docs * BUG: Fix typecasting problem in scipy.sparse.lil_matrix truediv * BUG: In least_squares make initial guess sufficiently feasible w.r.t. to bounds for method 'trf' * BUG: fix pow method for sparrays with power zero * BUG: set idx_dtype in sparse dia_array.tocoo - Drop patch intc.patch, included. ------------------------------------------------------------------- Mon Oct 9 06:52:54 UTC 2023 - ecsos <ecsos@opensuse.org> - Let it build for Leap 15.6 also. ------------------------------------------------------------------- Thu Jul 27 13:31:24 UTC 2023 - Markéta Machová <mmachova@suse.com> - Add upstream intc.patch to fix gh#scipy/scipy#18603 ------------------------------------------------------------------- Tue Jul 25 10:04:04 UTC 2023 - Markéta Machová <mmachova@suse.com> - Update to 1.11.1 * Several scipy.sparse array API improvements, including sparse.sparray, a new public base class distinct from the older sparse.spmatrix class, proper 64-bit index support, and numerous deprecations paving the way to a modern sparse array experience. * scipy.stats added tools for survival analysis, multiple hypothesis testing, sensitivity analysis, and working with censored data. * A new function was added for quasi-Monte Carlo integration, and linear algebra functions det and lu now accept nD-arrays. * An axes argument was added broadly to ndimage functions, facilitating analysis of stacked image data. ------------------------------------------------------------------- Thu Jun 29 07:21:08 UTC 2023 - Andreas Schneider <asn@cryptomilk.org> - Use sle15_python_module_pythons - Require GCC >= 8 ------------------------------------------------------------------- Fri Mar 10 14:18:09 UTC 2023 - Martin Liška <mliska@suse.cz> - Fix i686 tests for GCC 13 due to: https://gcc.gnu.org/gcc-13/porting_to.html#excess-precision ------------------------------------------------------------------- Sun Feb 26 00:27:35 UTC 2023 - Ben Greiner <code@bnavigator.de> - Update to 1.10.1 * bug-fix release with no new features compared to 1.10.0 - Drop scipy-pr17717-ro-interpn.patch ------------------------------------------------------------------- Mon Jan 16 22:06:27 UTC 2023 - Ben Greiner <code@bnavigator.de> - Highlights of the 1.10.0 release * A new dedicated datasets submodule (scipy.datasets) has been added, and is now preferred over usage of scipy.misc for dataset retrieval. * A new scipy.interpolate.make_smoothing_spline function was added.

Fixes test_kolmogorov.py Fatal Python error: Floating point exception which is a double floating-point test. ------------------------------------------------------------------- Mon Mar 28 18:16:15 UTC 2022 - Ben Greiner <code@bnavigator.de> - Update to version 1.8.0 * https://scipy.github.io/devdocs/release.1.8.0.html * SciPy 1.8.0 is the culmination of 6 months of hard work. It contains many new features, numerous bug-fixes, improved test coverage and better documentation. There have been a number of deprecations and API changes in this release. All users are encouraged to upgrade to this release, as there are a large number of bug-fixes and optimizations. Before upgrading, we recommend that users check that their own code does not use deprecated SciPy functionality (to do so, run your code with python -Wd and check for `DeprecationWarning`s). * A sparse array API has been added for early testing and feedback; this work is ongoing, and users should expect minor API refinements over the next few releases. * The sparse SVD library PROPACK is now vendored with SciPy, and an interface is exposed via scipy.sparse.svds with solver='PROPACK'. It is currently default-off due to potential issues on Windows that we aim to resolve in the next release, but can be optionally enabled at runtime for friendly testing with an environment variable setting of USE_PROPACK=1. * A new scipy.stats.sampling submodule that leverages the UNU.RAN C library to sample from arbitrary univariate non-uniform continuous and discrete distributions * All namespaces that were private but happened to miss underscores in their names have been deprecated. * Backwards incompatible changes - SciPy has raised the minimum compiler versions to GCC 6.3 on linux and VS2019 on windows. In particular, this means that SciPy may now use C99 and C++14 features. For more details see here. - The result for empty bins for scipy.stats.binned_statistic with the builtin 'std' metric is now nan, for consistency with np.std. - The function scipy.spatial.distance.wminkowski has been removed. To achieve the same results as before, please use the minkowski distance function with the (optional) w= keyword-argument for the given weight. ------------------------------------------------------------------- Sat Jan 29 20:44:30 UTC 2022 -

Paolo Stivanin <info@paolostivanin.com> - Update to 1.6.0: * scipy.ndimage improvements: Fixes and ehancements to boundary extension modes for interpolation functions. Support for complex-valued inputs in many filtering and interpolation functions. New grid_mode option for scipy.ndimage.zoom to enable results consistent with scikit-image’s rescale. * scipy.optimize.linprog has fast, new methods for large, sparse problems from the HiGHS library. * scipy.stats improvements including new distributions, a new test, and enhancements to existing distributions and tests * scipy.special now has improved support for 64-bit LAPACK backend * scipy.odr now has support for 64-bit integer BLAS * scipy.odr.ODR has gained an optional overwrite argument so that existing files may be overwritten. * scipy.cluster.hierarchy.DisjointSet has been added for incremental connectivity queries. * scipy.cluster.hierarchy.dendrogram return value now also includes leaf color information in leaves_color_list. * scipy.interpolate.interp1d has a new method nearest-up, similar to the existing method nearest but rounds half-integers up instead of down. * scipy.ndimage.convolve, scipy.ndimage.correlate and their 1d counterparts now accept both complex-valued images and/or complex-valued filter kernels.

No build time dependency to suitesparse is required (jsc#SLE-11732). - Get rid of site.cfg entirely as it is used nowhwere in scipy. ------------------------------------------------------------------- Wed Jan 15 12:56:20 UTC 2020 - Tomáš Chvátal <tchvatal@suse.com> - Fix pybind11 devel dependency to match real name ------------------------------------------------------------------- Fri Dec 20 01:27:36 UTC 2019 - Todd R <toddrme2178@gmail.com> - Update to 1.4.1 * SciPy 1.4.1 is a bug-fix release with no new features compared to 1.4.0. Importantly, it aims to fix a problem where an older version of pybind11 may cause a segmentation fault when imported alongside incompatible libraries. ------------------------------------------------------------------- Tue Dec 17 20:48:57 UTC 2019 - Todd R <toddrme2178@gmail.com> - Update to 1.4.0 + Highlights of this release * a new submodule, `scipy.fft`, now supersedes `scipy.fftpack`; this means support for ``long double`` transforms, faster multi-dimensional transforms, improved algorithm time complexity, release of the global intepreter lock, and control over threading behavior * support for ``pydata/sparse`` arrays in `scipy.sparse.linalg` * substantial improvement to the documentation and functionality of several `scipy.special` functions, and some new additions * the generalized inverse Gaussian distribution has been added to `scipy.stats` * an implementation of the Edmonds-Karp algorithm in `scipy.sparse.csgraph.maximum_flow` * `scipy.spatial.SphericalVoronoi` now supports n-dimensional input, has linear memory complexity, improved performance, and supports single-hemisphere generators + New features > Infrastructure * Documentation can now be built with ``runtests.py --doc`` * A ``Dockerfile`` is now available in the ``scipy/scipy-dev`` repository to acilitate getting started with SciPy development. > `scipy.constants` improvements * `scipy.constants` has been updated with the CODATA 2018 constants. > `scipy.fft` added * `scipy.fft` is a new submodule that supersedes the `scipy.fftpack` submodule. or the most part, this is a drop-in replacement for ``numpy.fft`` and scipy.fftpack` alike. With some important differences, `scipy.fft`: * uses NumPy's conventions for real transforms (``rfft``). This means the eturn value is a complex array, half the size of the full ``fft`` output. his is different from the output of ``fftpack`` which returned a real array epresenting complex components packed together. * the inverse real to real transforms (``idct`` and ``idst``) are normalized or ``norm=None`` in thesame way as ``ifft``. This means the identity `idct(dct(x)) == x`` is now ``True`` for all norm modes. * does not include the convolutions or pseudo-differential operators rom ``fftpack``. * This submodule is based on the ``pypocketfft`` library, developed by the uthor of ``pocketfft`` which was recently adopted by NumPy as well. `pypocketfft`` offers a number of advantages over fortran ``FFTPACK``: * support for long double (``np.longfloat``) precision transforms. * faster multi-dimensional transforms using vectorisation * Bluestein’s algorithm removes the worst-case ``O(n^2)`` complexity of `FFTPACK`` * the global interpreter lock (``GIL``) is released during transforms * optional multithreading of multi-dimensional transforms via the ``workers`` rgument * Note that `scipy.fftpack` has not been deprecated and will continue to be aintained but is now considered legacy. New code is recommended to use scipy.fft` instead, where possible. > `scipy.fftpack` improvements * `scipy.fftpack` now uses pypocketfft to perform its FFTs, offering the same peed and accuracy benefits listed for scipy.fft above but without the mproved API. > `scipy.integrate` improvements * The function `scipy.integrate.solve_ivp` now has an ``args`` argument. his allows the user-defined functions passed to the function to have dditional parameters without having to create wrapper functions or ambda expressions for them. * `scipy.integrate.solve_ivp` can now return a ``y_events`` attribute epresenting the solution of the ODE at event times * New ``OdeSolver`` is implemented --- ``DOP853``. This is a high-order explicit unge-Kutta method originally implemented in Fortran. Now we provide a pure ython implementation usable through ``solve_ivp`` with all its features. * `scipy.integrate.quad` provides better user feedback when break points are pecified with a weighted integrand. * `scipy.integrate.quad_vec` is now available for general purpose integration f vector-valued functions > `scipy.interpolate` improvements * `scipy.interpolate.pade` now handles complex input data gracefully * `scipy.interpolate.Rbf` can now interpolate multi-dimensional functions > `scipy.io` improvements * `scipy.io.wavfile.read` can now read data from a `WAV` file that has a alformed header, similar to other modern `WAV` file parsers * `scipy.io.FortranFile` now has an expanded set of available ``Exception`` lasses for handling poorly-formatted files > `scipy.linalg` improvements * The function ``scipy.linalg.subspace_angles(A, B)`` now gives correct esults for complex-valued matrices. Before this, the function only returned orrect values for real-valued matrices. * New boolean keyword argument ``check_finite`` for `scipy.linalg.norm`; whether o check that the input matrix contains only finite numbers. Disabling may ive a performance gain, but may result in problems (crashes, non-termination) f the inputs do contain infinities or NaNs. * `scipy.linalg.solve_triangular` has improved performance for a C-ordered riangular matrix * ``LAPACK`` wrappers have been added for ``?geequ``, ``?geequb``, ``?syequb``, nd ``?heequb`` * Some performance improvements may be observed due to an internal optimization n operations involving LAPACK routines via ``_compute_lwork``. This is articularly true for operations on small arrays. * Block ``QR`` wrappers are now available in `scipy.linalg.lapack` > `scipy.optimize` improvements * It is now possible to use linear and non-linear constraints with scipy.optimize.differential_evolution`. * `scipy.optimize.linear_sum_assignment` has been re-written in C++ to improve erformance, and now allows input costs to be infinite. * A ``ScalarFunction.fun_and_grad`` method was added for convenient simultaneous etrieval of a function and gradient evaluation * `scipy.optimize.minimize` ``BFGS`` method has improved performance by avoiding uplicate evaluations in some cases * Better user feedback is provided when an objective function returns an array nstead of a scalar. > `scipy.signal` improvements * Added a new function to calculate convolution using the overlap-add method, amed `scipy.signal.oaconvolve`. Like `scipy.signal.fftconvolve`, this unction supports specifying dimensions along which to do the convolution. * `scipy.signal.cwt` now supports complex wavelets. * The implementation of ``choose_conv_method`` has been updated to reflect the ew FFT implementation. In addition, the performance has been significantly mproved (with rather drastic improvements in edge cases). * The function ``upfirdn`` now has a ``mode`` keyword argument that can be used o select the signal extension mode used at the signal boundaries. These modes re also available for use in ``resample_poly`` via a newly added ``padtype`` rgument. * `scipy.signal.sosfilt` now benefits from Cython code for improved performance * `scipy.signal.resample` should be more efficient by leveraging ``rfft`` when ossible > `scipy.sparse` improvements * It is now possible to use the LOBPCG method in `scipy.sparse.linalg.svds`. * `scipy.sparse.linalg.LinearOperator` now supports the operation ``rmatmat`` or adjoint matrix-matrix multiplication, in addition to ``rmatvec``. * Multiple stability updates enable float32 support in the LOBPCG eigenvalue olver for symmetric and Hermitian eigenvalues problems in `scipy.sparse.linalg.lobpcg``. * A solver for the maximum flow problem has been added as scipy.sparse.csgraph.maximum_flow`. * `scipy.sparse.csgraph.maximum_bipartite_matching` now allows non-square inputs, o longer requires a perfect matching to exist, and has improved performance. * `scipy.sparse.lil_matrix` conversions now perform better in some scenarios * Basic support is available for ``pydata/sparse`` arrays in scipy.sparse.linalg` * `scipy.sparse.linalg.spsolve_triangular` now supports the ``unit_diagonal`` rgument to improve call signature similarity with its dense counterpart, scipy.linalg.solve_triangular` * ``assertAlmostEqual`` may now be used with sparse matrices, which have added upport for ``__round__`` > `scipy.spatial` improvements * The bundled Qhull library was upgraded to version 2019.1, fixing several ssues. Scipy-specific patches are no longer applied to it. * `scipy.spatial.SphericalVoronoi` now has linear memory complexity, improved erformance, and supports single-hemisphere generators. Support has also been dded for handling generators that lie on a great circle arc (geodesic input) nd for generators in n-dimensions. * `scipy.spatial.transform.Rotation` now includes functions for calculation of a ean rotation, generation of the 3D rotation groups, and reduction of rotations ith rotational symmetries. * `scipy.spatial.transform.Slerp` is now callable with a scalar argument * `scipy.spatial.voronoi_plot_2d` now supports furthest site Voronoi diagrams * `scipy.spatial.Delaunay` and `scipy.spatial.Voronoi` now have attributes or tracking whether they are furthest site diagrams > `scipy.special` improvements * The Voigt profile has been added as `scipy.special.voigt_profile`. * A real dispatch has been added for the Wright Omega function `scipy.special.wrightomega`). * The analytic continuation of the Riemann zeta function has been added. (The iemann zeta function is the one-argument variant of `scipy.special.zeta`.) * The complete elliptic integral of the first kind (`scipy.special.ellipk`) is ow available in `scipy.special.cython_special`. * The accuracy of `scipy.special.hyp1f1` for real arguments has been improved. * The documentation of many functions has been improved. > `scipy.stats` improvements * `scipy.stats.multiscale_graphcorr` added as an independence test that perates on high dimensional and nonlinear data sets. It has higher statistical ower than other `scipy.stats` tests while being the only one that operates on ultivariate data. * The generalized inverse Gaussian distribution (`scipy.stats.geninvgauss`) has een added. * It is now possible to efficiently reuse `scipy.stats.binned_statistic_dd` ith new values by providing the result of a previous call to the function. * `scipy.stats.hmean` now handles input with zeros more gracefully. * The beta-binomial distribution is now available in `scipy.stats.betabinom`. * `scipy.stats.zscore`, `scipy.stats.circmean`, `scipy.stats.circstd`, and scipy.stats.circvar` now support the ``nan_policy`` argument for enhanced andling of ``NaN`` values * `scipy.stats.entropy` now accepts an ``axis`` argument * `scipy.stats.gaussian_kde.resample` now accepts a ``seed`` argument to empower eproducibility * `scipy.stats.kendalltau` performance has improved, especially for large inputs, ue to improved cache usage * `scipy.stats.truncnorm` distribution has been rewritten to support much wider ails + Deprecated features > `scipy` deprecations * Support for NumPy functions exposed via the root SciPy namespace is deprecated nd will be removed in 2.0.0. For example, if you use ``scipy.rand`` or `scipy.diag``, you should change your code to directly use `numpy.random.default_rng`` or ``numpy.diag``, respectively. hey remain available in the currently continuing Scipy 1.x release series. * The exception to this rule is using ``scipy.fft`` as a function -- mod:`scipy.fft` is now meant to be used only as a module, so the ability to all ``scipy.fft(...)`` will be removed in SciPy 1.5.0. * In `scipy.spatial.Rotation` methods ``from_dcm``, ``as_dcm`` were renamed to `from_matrix``, ``as_matrix`` respectively. The old names will be removed in ciPy 1.6.0. * Method ``Rotation.match_vectors`` was deprecated in favor of `Rotation.align_vectors``, which provides a more logical and eneral API to the same functionality. The old method ill be removed in SciPy 1.6.0. + Backwards incompatible changes > `scipy.special` changes * The deprecated functions ``hyp2f0``, ``hyp1f2``, and ``hyp3f0`` have been emoved. * The deprecated function ``bessel_diff_formula`` has been removed. * The function ``i0`` is no longer registered with ``numpy.dual``, so that `numpy.dual.i0`` will unconditionally refer to the NumPy version regardless f whether `scipy.special` is imported. * The function ``expn`` has been changed to return ``nan`` outside of its omain of definition (``x, n < 0``) instead of ``inf``. > `scipy.sparse` changes * Sparse matrix reshape now raises an error if shape is not two-dimensional, rather than guessing what was meant. The behavior is now the same as before ciPy 1.1.0. * ``CSR`` and ``CSC`` sparse matrix classes should now return empty matrices f the same type when indexed out of bounds. Previously, for some versions f SciPy, this would raise an ``IndexError``. The change is largely motivated y greater consistency with ``ndarray`` and ``numpy.matrix`` semantics. > `scipy.signal` changes * `scipy.signal.resample` behavior for length-1 signal inputs has been ixed to output a constant (DC) value rather than an impulse, consistent with he assumption of signal periodicity in the FFT method. * `scipy.signal.cwt` now performs complex conjugation and time-reversal of avelet data, which is a backwards-incompatible bugfix for ime-asymmetric wavelets. > `scipy.stats` changes * `scipy.stats.loguniform` added with better documentation as (an alias for `scipy.stats.reciprocal``). ``loguniform`` generates random variables hat are equally likely in the log space; e.g., ``1``, ``10`` and ``100`` re all equally likely if ``loguniform(10 ** 0, 10 ** 2).rvs()`` is used. + Other changes * The ``LSODA`` method of `scipy.integrate.solve_ivp` now correctly detects stiff roblems. * `scipy.spatial.cKDTree` now accepts and correctly handles empty input data * `scipy.stats.binned_statistic_dd` now calculates the standard deviation tatistic in a numerically stable way. * `scipy.stats.binned_statistic_dd` now throws an error if the input data ontains either ``np.nan`` or ``np.inf``. Similarly, in `scipy.stats` now all ontinuous distributions' ``.fit()`` methods throw an error if the input data ontain any instance of either ``np.nan`` or ``np.inf``. - Rebase no_implicit_decl.patch ------------------------------------------------------------------- Tue Dec 10 14:24:29 UTC 2019 - Todd R <toddrme2178@gmail.com> - Update to 1.3.3 * Fix deadlock on osx for python 3.8 * MAINT: TST: Skip tests with multiprocessing that use "spawn" start method ------------------------------------------------------------------- Tue Nov 19 20:08:41 UTC 2019 - Todd R <toddrme2178@gmail.com> - Update to 1.3.2 * Bug in unique_roots in scipy.signal.signaltools.py for roots... * Optimizers reporting success when the minimum is NaN * ValueError raised if scipy.sparse.linalg.expm recieves array... * linprog(method='revised simplex') doctest bug * Graph shortest path with Floyd-Warshall removes explicit zeros. * BUG: stats: Formula for the variance of the noncentral F distribution... * BUG: Assignation issues in csr_matrix with fancy indexing * root_scalar fails when passed a function wrapped with functools.lru_cache * CI: travis osx build failure * macOS build failure in SuperLU on maintenance/1.3.x * Typo in sp.stats.wilcoxon docstring ------------------------------------------------------------------- Fri Aug 16 15:00:19 UTC 2019 - Todd R <toddrme2178@gmail.com> - Update to 1.3.1 * BUG: Empty data handling of (c)KDTrees * lsoda fails to detect stiff problem when called from solve_ivp * sparse matrices indexing with scipy 1.3 * Exception in loadarff with quoted nominal attributes in scipy... * DOC/REL: Some sections of the release notes are not nested correctly. * BUG: optimize: `linprog` failing TestLinprogSimplexBland::test_unbounded_below_no_presolve_corrected * TST: Travis CI fails (with pytest 5.0 ?) * CircleCI doc build failing on new warnings * Scipy 1.3.0 build broken in AIX * BUG: scipy.spatial.HalfspaceIntersection works incorrectly * BUG: cKDTree GIL handling is incorrect * TST: master branch CI failures * BUG: ckdtree query_ball_point errors on discontiguous input * BUG: No warning on PchipInterpolator changing from bernstein base to local power base ------------------------------------------------------------------- Sun May 19 02:47:42 UTC 2019 - Todd R <toddrme2178@gmail.com> - Update to 1.3.0 + Highlights of this release * Three new ``stats`` functions, a rewrite of ``pearsonr``, and an exact computation of the Kolmogorov-Smirnov two-sample test * A new Cython API for bounded scalar-function root-finders in `scipy.optimize` * Substantial ``CSR`` and ``CSC`` sparse matrix indexing performance improvements * Added support for interpolation of rotations with continuous angular rate and acceleration in ``RotationSpline`` + New features > `scipy.interpolate` improvements * A new class ``CubicHermiteSpline`` is introduced. It is a piecewise-cubic interpolator which matches observed values and first derivatives. Existing cubic interpolators ``CubicSpline``, ``PchipInterpolator`` and ``Akima1DInterpolator`` were made subclasses of ``CubicHermiteSpline``. > `scipy.io` improvements * For the Attribute-Relation File Format (ARFF) `scipy.io.arff.loadarff` now supports relational attributes. * `scipy.io.mmread` can now parse Matrix Market format files with empty lines. > `scipy.linalg` improvements * Added wrappers for ``?syconv`` routines, which convert a symmetric matrix given by a triangular matrix factorization into two matrices and vice versa. * `scipy.linalg.clarkson_woodruff_transform` now uses an algorithm that leverages sparsity. This may provide a 60-90 percent speedup for dense input matrices. Truly sparse input matrices should also benefit from the improved sketch algorithm, which now correctly runs in ``O(nnz(A))`` time. * Added new functions to calculate symmetric Fiedler matrices and Fiedler companion matrices, named `scipy.linalg.fiedler` and `scipy.linalg.fiedler_companion`, respectively. These may be used for root finding. > `scipy.ndimage` improvements * Gaussian filter performances may improve by an order of magnitude in some cases, thanks to removal of a dependence on ``np.polynomial``. This may impact `scipy.ndimage.gaussian_filter` for example. > `scipy.optimize` improvements * The `scipy.optimize.brute` minimizer obtained a new keyword ``workers``, which can be used to parallelize computation. * A Cython API for bounded scalar-function root-finders in `scipy.optimize` is available in a new module `scipy.optimize.cython_optimize` via ``cimport``. This API may be used with ``nogil`` and ``prange`` to loop over an array of function arguments to solve for an array of roots more quickly than with pure Python. * ``'interior-point'`` is now the default method for ``linprog``, and ``'interior-point'`` now uses SuiteSparse for sparse problems when the required scikits (scikit-umfpack and scikit-sparse) are available. On benchmark problems (gh-10026), execution time reductions by factors of 2-3 were typical. Also, a new ``method='revised simplex'`` has been added. It is not as fast or robust as ``method='interior-point'``, but it is a faster, more robust, and equally accurate substitute for the legacy ``method='simplex'``. * ``differential_evolution`` can now use a ``Bounds`` class to specify the bounds for the optimizing argument of a function. * `scipy.optimize.dual_annealing` performance improvements related to vectorisation of some internal code. > `scipy.signal` improvements * Two additional methods of discretization are now supported by `scipy.signal.cont2discrete`: ``impulse`` and ``foh``. * `scipy.signal.firls` now uses faster solvers * `scipy.signal.detrend` now has a lower physical memory footprint in some cases, which may be leveraged using the new ``overwrite_data`` keyword argument * `scipy.signal.firwin` ``pass_zero`` argument now accepts new string arguments that allow specification of the desired filter type: ``'bandpass'``, ``'lowpass'``, ``'highpass'``, and ``'bandstop'`` * `scipy.signal.sosfilt` may have improved performance due to lower retention of the global interpreter lock (GIL) in algorithm > `scipy.sparse` improvements * A new keyword was added to ``csgraph.dijsktra`` that allows users to query the shortest path to ANY of the passed in indices, as opposed to the shortest path to EVERY passed index. * `scipy.sparse.linalg.lsmr` performance has been improved by roughly 10 percent on large problems * Improved performance and reduced physical memory footprint of the algorithm used by `scipy.sparse.linalg.lobpcg` * ``CSR`` and ``CSC`` sparse matrix fancy indexing performance has been improved substantially > `scipy.spatial` improvements * `scipy.spatial.ConvexHull` now has a ``good`` attribute that can be used alongsize the ``QGn`` Qhull options to determine which external facets of a convex hull are visible from an external query point. * `scipy.spatial.cKDTree.query_ball_point` has been modernized to use some newer Cython features, including GIL handling and exception translation. An issue with ``return_sorted=True`` and scalar queries was fixed, and a new mode named ``return_length`` was added. ``return_length`` only computes the length of the returned indices list instead of allocating the array every time. * `scipy.spatial.transform.RotationSpline` has been added to enable interpolation of rotations with continuous angular rates and acceleration > `scipy.stats` improvements * Added a new function to compute the Epps-Singleton test statistic, `scipy.stats.epps_singleton_2samp`, which can be applied to continuous and discrete distributions. * New functions `scipy.stats.median_absolute_deviation` and `scipy.stats.gstd` (geometric standard deviation) were added. The `scipy.stats.combine_pvalues` method now supports ``pearson``, ``tippett`` and ``mudholkar_george`` pvalue combination methods. * The `scipy.stats.ortho_group` and `scipy.stats.special_ortho_group` ``rvs(dim)`` functions' algorithms were updated from a ``O(dim^4)`` implementation to a ``O(dim^3)`` which gives large speed improvements for ``dim>100``. * A rewrite of `scipy.stats.pearsonr` to use a more robust algorithm, provide meaningful exceptions and warnings on potentially pathological input, and fix at least five separate reported issues in the original implementation. * Improved the precision of ``hypergeom.logcdf`` and ``hypergeom.logsf``. * Added exact computation for Kolmogorov-Smirnov (KS) two-sample test, replacing the previously approximate computation for the two-sided test `stats.ks_2samp`. Also added a one-sided, two-sample KS test, and a keyword ``alternative`` to `stats.ks_2samp`. + Backwards incompatible changes > `scipy.interpolate` changes * Functions from ``scipy.interpolate`` (``spleval``, ``spline``, ``splmake``, and ``spltopp``) and functions from ``scipy.misc`` (``bytescale``, ``fromimage``, ``imfilter``, ``imread``, ``imresize``, ``imrotate``, ``imsave``, ``imshow``, ``toimage``) have been removed. The former set has been deprecated since v0.19.0 and the latter has been deprecated since v1.0.0. Similarly, aliases from ``scipy.misc`` (``comb``, ``factorial``, ``factorial2``, ``factorialk``, ``logsumexp``, ``pade``, ``info``, ``source``, ``who``) which have been deprecated since v1.0.0 are removed. `SciPy documentation for v1.1.0 <https://docs.scipy.org/doc/scipy-1.1.0/reference/misc.html>`__ can be used to track the new import locations for the relocated functions. > `scipy.linalg` changes * For ``pinv``, ``pinv2``, and ``pinvh``, the default cutoff values are changed for consistency (see the docs for the actual values). > `scipy.optimize` changes * The default method for ``linprog`` is now ``'interior-point'``. The method's robustness and speed come at a cost: solutions may not be accurate to machine precision or correspond with a vertex of the polytope defined by the constraints. To revert to the original simplex method, include the argument ``method='simplex'``. > `scipy.stats` changes * Previously, ``ks_2samp(data1, data2)`` would run a two-sided test and return the approximated p-value. The new signature, ``ks_2samp(data1, data2, alternative="two-sided", method="auto")``, still runs the two-sided test by default but returns the exact p-value for small samples and the approximated value for large samples. ``method="asymp"`` would be equivalent to the old version but ``auto`` is the better choice. + Other changes * Our tutorial has been expanded with a new section on global optimizers * There has been a rework of the ``stats.distributions`` tutorials. * `scipy.optimize` now correctly sets the convergence flag of the result to ``CONVERR``, a convergence error, for bounded scalar-function root-finders if the maximum iterations has been exceeded, ``disp`` is false, and ``full_output`` is true. * `scipy.optimize.curve_fit` no longer fails if ``xdata`` and ``ydata`` dtypes differ; they are both now automatically cast to ``float64``. * `scipy.ndimage` functions including ``binary_erosion``, ``binary_closing``, and ``binary_dilation`` now require an integer value for the number of iterations, which alleviates a number of reported issues. * Fixed normal approximation in case ``zero_method == "pratt"`` in `scipy.stats.wilcoxon`. * Fixes for incorrect probabilities, broadcasting issues and thread-safety related to stats distributions setting member variables inside ``_argcheck()``. * `scipy.optimize.newton` now correctly raises a ``RuntimeError``, when default arguments are used, in the case that a derivative of value zero is obtained, which is a special case of failing to converge. * A draft toolchain roadmap is now available, laying out a compatibility plan including Python versions, C standards, and NumPy versions. - Python 2 is no longer supported ------------------------------------------------------------------- Tue Mar 19 17:08:19 UTC 2019 - Todd R <toddrme2178@gmail.com> - Update to 1.2.1 * SyntaxError: Non-ASCII character 'xe2' in file scipy/stats/_continuous_distns.py on line 3346, but no encoding declared * Version 1.2.0 introduces `too many indices for array` error in `optimize.newton()` * scipy.stats.gaussian_kde normalizes the weights keyword argument externally. * scipy.linalg.qr_update gives NaN result * CI: Is scipy.scipy Windows Python36-32bit-full working? ------------------------------------------------------------------- Fri Mar 1 20:45:50 UTC 2019 - Matej Cepl <mcepl@suse.com> - Use direct number in the Version tag ------------------------------------------------------------------- Tue Feb 12 08:55:55 UTC 2019 - Egbert Eich <eich@suse.com> bsc#1130564: Apply update from the openSUSE package - Properly create and tear down default version links when the HPC master packages are installed/uninstalled. - Make use of %hpc_modules_init to make modules also known to client. - Module file: * remove PATH element.

The sources are not as cleanly separated as the changelog implied. ------------------------------------------------------------------- Mon Jul 27 09:26:20 UTC 2015 - toddrme2178@gmail.com - Update to 0.16.0 * Highlights of this release include: - A Cython API for BLAS/LAPACK in scipy.linalg - A new benchmark suite. It's now straightforward to add new benchmarks, and they're routinely included with performance enhancement PRs. - Support for the second order sections (SOS) format in scipy.signal. * New features - Benchmark suite + The benchmark suite has switched to using Airspeed Velocity for benchmarking. - scipy.linalg improvements + A full set of Cython wrappers for BLAS and LAPACK has been added in the modules scipy.linalg.cython_blas and scipy.linalg.cython_lapack. In Cython, these wrappers can now be cimported from their corresponding modules and used without linking directly against BLAS or LAPACK. + The functions scipy.linalg.qr_delete, scipy.linalg.qr_insert and scipy.linalg.qr_update for updating QR decompositions were added. + The function scipy.linalg.solve_circulant solves a linear system with a circulant coefficient matrix. + The function scipy.linalg.invpascal computes the inverse of a Pascal matrix. + The function scipy.linalg.solve_toeplitz, a Levinson-Durbin Toeplitz solver, was added. + Added wrapper for potentially useful LAPACK function *lasd4. It computes the square root of the i-th updated eigenvalue of a positive symmetric rank-one modification to a positive diagonal matrix. See its LAPACK documentation and unit tests for it to get more info. + Added two extra wrappers for LAPACK least-square solvers. Namely, they are *gelsd and *gelsy. + Wrappers for the LAPACK *lange functions, which calculate various matrix norms, were added. + Wrappers for *gtsv and *ptsv, which solve A*X = B for tri-diagonal matrix A, were added. - scipy.signal improvements + Support for second order sections (SOS) as a format for IIR filters was added. The new functions are: * scipy.signal.sosfilt * scipy.signal.sosfilt_zi, * scipy.signal.sos2tf * scipy.signal.sos2zpk * scipy.signal.tf2sos * scipy.signal.zpk2sos. + Additionally, the filter design functions iirdesign, iirfilter, butter, cheby1, cheby2, ellip, and bessel can return the filter in the SOS format. + The function scipy.signal.place_poles, which provides two methods to place poles for linear systems, was added. + The option to use Gustafsson's method for choosing the initial conditions of the forward and backward passes was added to scipy.signal.filtfilt. + New classes TransferFunction, StateSpace and ZerosPolesGain were added. These classes are now returned when instantiating scipy.signal.lti. Conversion between those classes can be done explicitly now. + An exponential (Poisson) window was added as scipy.signal.exponential, and a Tukey window was added as scipy.signal.tukey. + The function for computing digital filter group delay was added as scipy.signal.group_delay. + The functionality for spectral analysis and spectral density estimation has been significantly improved: scipy.signal.welch became ~8x faster and the functions scipy.signal.spectrogram, scipy.signal.coherence and scipy.signal.csd (cross-spectral density) were added. + scipy.signal.lsim was rewritten - all known issues are fixed, so this function can now be used instead of lsim2; lsim is orders of magnitude faster than lsim2 in most cases. - scipy.sparse improvements + The function scipy.sparse.norm, which computes sparse matrix norms, was added. + The function scipy.sparse.random, which allows to draw random variates from an arbitrary distribution, was added. - scipy.spatial improvements + scipy.spatial.cKDTree has seen a major rewrite, which improved the performance of the query method significantly, added support for parallel queries, pickling, and options that affect the tree layout. See pull request 4374 for more details. + The function scipy.spatial.procrustes for Procrustes analysis (statistical shape analysis) was added. - scipy.stats improvements + The Wishart distribution and its inverse have been added, as scipy.stats.wishart and scipy.stats.invwishart. + The Exponentially Modified Normal distribution has been added as scipy.stats.exponnorm. + The Generalized Normal distribution has been added as scipy.stats.gennorm. + All distributions now contain a random_state property and allow specifying a specific numpy.random.RandomState random number generator when generating random variates. + Many statistical tests and other scipy.stats functions that have multiple return values now return namedtuples. See pull request 4709 for details. - scipy.optimize improvements + A new derivative-free method DF-SANE has been added to the nonlinear equation system solving function scipy.optimize.root. * Deprecated features - scipy.stats.pdf_fromgamma is deprecated. This function was undocumented, untested and rarely used. Statsmodels provides equivalent functionality with statsmodels.distributions.ExpandedNormal. - scipy.stats.fastsort is deprecated. This function is unnecessary, numpy.argsort can be used instead. - scipy.stats.signaltonoise and scipy.stats.mstats.signaltonoise are deprecated. These functions did not belong in scipy.stats and are rarely used. See issue #609 for details. - scipy.stats.histogram2 is deprecated. This function is unnecessary, numpy.histogram2d can be used instead. * Backwards incompatible changes - The deprecated global optimizer scipy.optimize.anneal was removed. - The following deprecated modules have been removed. They had been deprecated since Scipy 0.12.0, the functionality should be accessed as scipy.linalg.blas and scipy.linalg.lapack. + scipy.lib.blas + scipy.lib.lapack + scipy.linalg.cblas + scipy.linalg.fblas + scipy.linalg.clapack + scipy.linalg.flapack. - The deprecated function scipy.special.all_mat has been removed. - These deprecated functions have been removed from scipy.stats: + scipy.stats.fprob + scipy.stats.ksprob + scipy.stats.zprob + scipy.stats.randwcdf + scipy.stats.randwppf * Other changes - The version numbering for development builds has been updated to comply with PEP 440. - Building with python setup.py develop is now supported. - Move Cython imports to another package ------------------------------------------------------------------- Mon Mar 2 15:57:12 UTC 2015 - toddrme2178@gmail.com - update to version 0.15.1: * #4413: BUG: Tests too strict, f2py doesn't have to overwrite this array * #4417: BLD: avoid using NPY_API_VERSION to check not using deprecated... * #4418: Restore and deprecate scipy.linalg.calc_work ------------------------------------------------------------------- Mon Jan 12 13:36:00 UTC 2015 - toddrme2178@gmail.com - Update to 0.15.0 * New features * scipy.optimize improvements * scipy.optimize.linprog now provides a generic linear programming similar to the way scipy.optimize.minimize provides a generic interface to nonlinear programming optimizers. Currently the only method supported is simplex which provides a two-phase, dense-matrix-based simplex algorithm. Callbacks functions are supported,allowing the user to monitor the progress of the algorithm. * The differential_evolution function is available from the scipy.optimize module. Differential Evolution is an algorithm used for finding the global minimum of multivariate functions. It is stochastic in nature (does not use gradient methods), and can search large areas of candidate space, but often requires larger numbers of function evaluations than conventional gradient based techniques. * scipy.signal improvements * The function max_len_seq was added, which computes a Maximum Length Sequence (MLS) signal. * scipy.integrate improvements * The interface between the scipy.integrate module and the QUADPACK library was redesigned. It is now possible to use scipy.integrate to integrate multivariate ctypes functions, thus avoiding callbacks to Python and providing better performance, especially for complex integrand functions. * scipy.sparse improvements * scipy.sparse.linalg.svds now takes a LinearOperator as its main input. * scipy.stats improvements * Added a Dirichlet distribution as multivariate distribution. * The new function `scipy.stats.median_test` computes Mood's median test. * `scipy.stats.describe` returns a namedtuple rather than a tuple, allowing users to access results by index or by name. * Deprecated features * The scipy.weave module is deprecated. It was the only module never ported to Python 3.x, and is not recommended to be used for new code - use Cython instead. In order to support existing code, scipy.weave has been packaged separately: https://github.com/scipy/weave. It is a pure Python package, so can easily be installed with pip install weave. * scipy.special.bessel_diff_formula is deprecated. It is a private function, and therefore will be removed from the public API in a following release. * Backwards incompatible changes * scipy.ndimage * The functions scipy.ndimage.minimum_positions, scipy.ndimage.maximum_positions and scipy.ndimage.extrema return positions as ints instead of floats. * Other changes * scipy.integrate * The OPTPACK and QUADPACK code has been changed to use the LAPACK matrix solvers rather than the bundled LINPACK code. This means that there is no longer any need for the bundled LINPACK routines, so they have been removed. - Update copyright year ------------------------------------------------------------------- Mon Aug 11 08:53:11 UTC 2014 - toddrme2178@gmail.com - Switch to pypi download location - Minor spec file cleanups ------------------------------------------------------------------- Fri May 30 15:06:23 UTC 2014 - toddrme2178@gmail.com - Mark python-scipy-weave as deprecated. Please use python-weave package instead. ------------------------------------------------------------------- Thu May 8 10:16:00 UTC 2014 - toddrme2178@gmail.com - Update to version 0.14.0 * New features * scipy.interpolate improvements * A new wrapper function `scipy.interpolate.interpn` for interpolation onregular grids has been added. `interpn` supports linear and nearest-neighbor interpolation in arbitrary dimensions and spline interpolation in two dimensions. * Faster implementations of piecewise polynomials in power and Bernstein polynomial bases have been added as `scipy.interpolate.PPoly` and `scipy.interpolate.BPoly`. New users should use these in favor of `scipy.interpolate.PiecewisePolynomial`. * `scipy.interpolate.interp1d` now accepts non-monotonic inputs and sorts them. If performance is critical, sorting can be turned off by using the new ``assume_sorted`` keyword. * Functionality for evaluation of bivariate spline derivatives in ``scipy.interpolate`` has been added. * The new class `scipy.interpolate.Akima1DInterpolator` implements the piecewise cubic polynomial interpolation scheme devised by H. Akima. * Functionality for fast interpolation on regular, unevenly spaced grids in arbitrary dimensions has been added as `scipy.interpolate.RegularGridInterpolator` . * ``scipy.linalg`` improvements * The new function `scipy.linalg.dft` computes the matrix of the discrete Fourier transform. * A condition number estimation function for matrix exponential, `scipy.linalg.expm_cond`, has been added. * ``scipy.optimize`` improvements * A set of benchmarks for optimize, which can be run with ``optimize.bench()``, has been added. * `scipy.optimize.curve_fit` now has more controllable error estimation via the ``absolute_sigma`` keyword. * Support for passing custom minimization methods to ``optimize.minimize()`` and ``optimize.minimize_scalar()`` has been added, currently useful especially for combining ``optimize.basinhopping()`` with custom local optimizer routines. * ``scipy.stats`` improvements * A new class `scipy.stats.multivariate_normal` with functionality for multivariate normal random variables has been added. * A lot of work on the ``scipy.stats`` distribution framework has been done. Moment calculations (skew and kurtosis mainly) are fixed and verified, all examples are now runnable, and many small accuracy and performance improvements for individual distributions were merged. * The new function `scipy.stats.anderson_ksamp` computes the k-sample Anderson-Darling test for the null hypothesis that k samples come from the same parent population. * ``scipy.signal`` improvements * ``scipy.signal.iirfilter`` and related functions to design Butterworth, Chebyshev, elliptical and Bessel IIR filters now all use pole-zero ("zpk") format internally instead of using transformations to numerator/denominator format. The accuracy of the produced filters, especially high-order ones, is improved significantly as a result. * The new function `scipy.signal.vectorstrength` computes the vector strength, a measure of phase synchrony, of a set of events. * ``scipy.special`` improvements * The functions `scipy.special.boxcox` and `scipy.special.boxcox1p`, which compute the Box-Cox transformation, have been added. * ``scipy.sparse`` improvements * Significant performance improvement in CSR, CSC, and DOK indexing speed. * When using Numpy >= 1.9 (to be released in MM 2014), sparse matrices function correctly when given to arguments of ``np.dot``, ``np.multiply`` and other ufuncs. With earlier Numpy and Scipy versions, the results of such operations are undefined and usually unexpected. * Sparse matrices are no longer limited to ``2^31`` nonzero elements. They automatically switch to using 64-bit index data type for matrices containing more elements. User code written assuming the sparse matrices use int32 as the index data type will continue to work, except for such large matrices. Code dealing with larger matrices needs to accept either int32 or int64 indices. * Deprecated features * ``anneal`` * The global minimization function `scipy.optimize.anneal` is deprecated. All users should use the `scipy.optimize.basinhopping` function instead. * ``scipy.stats`` * ``randwcdf`` and ``randwppf`` functions are deprecated. All users should use distribution-specific ``rvs`` methods instead. * Probability calculation aliases ``zprob``, ``fprob`` and ``ksprob`` are deprecated. Use instead the ``sf`` methods of the corresponding distributions or the ``special`` functions directly. * ``scipy.interpolate`` * ``PiecewisePolynomial`` class is deprecated. * Backwards incompatible changes * scipy.special.lpmn * ``lpmn`` no longer accepts complex-valued arguments. A new function ``clpmn`` with uniform complex analytic behavior has been added, and it should be used instead. * scipy.sparse.linalg * Eigenvectors in the case of generalized eigenvalue problem are normalized to unit vectors in 2-norm, rather than following the LAPACK normalization convention. * The deprecated UMFPACK wrapper in ``scipy.sparse.linalg`` has been removed due to license and install issues. If available, ``scikits.umfpack`` is still used transparently in the ``spsolve`` and ``factorized`` functions. Otherwise, SuperLU is used instead in these functions. * scipy.stats * The deprecated functions ``glm``, ``oneway`` and ``cmedian`` have been removed from ``scipy.stats``. * ``stats.scoreatpercentile`` now returns an array instead of a list of percentiles. * scipy.interpolate * The API for computing derivatives of a monotone piecewise interpolation has changed: if `p` is a ``PchipInterpolator`` object, `p.derivative(der)` returns a callable object representing the derivative of `p`. For in-place derivatives use the second argument of the `__call__` method: `p(0.1, der=2)` evaluates the second derivative of `p` at `x=0.1`. * The method `p.derivatives` has been removed. ------------------------------------------------------------------- Sun Mar 2 04:22:42 UTC 2014 - arun@gmx.de - updated to version 0.13.3 Issues fixed: * 3148: fix a memory leak in ``ndimage.label``. * 3216: fix weave issue with too long file names for MSVC.
