Mailman 3 March 2017 - SciPy-User

migration of all scipy.org mailing lists
by Ralf Gommers March 22, 2017

March 22, 2017

Hi all, The server for the scipy.org mailing list is in very bad shape, so we (led by Didrik Pinte) are planning to complete the migration of active mailing lists to the python.org infrastructure and to decommission the lists than seem dormant/obsolete. The scipy-user mailing list was already moved to python.org a month or two ago, and that migration went smoothly. These are the lists we plan to migrate: astropy ipython-dev ipython-user numpy-discussion numpy-svn scipy-dev scipy-organizers scipy-svn And these we plan to retire: Announce APUG Ipython-tickets Mailman numpy-refactor numpy-refactor-git numpy-tickets Pyxg scipy-tickets NiPy-devel This will happen asap, likely within a day or two. So two requests: 1. If you see any issue with this plan, please reply and keep Didrik and myself on Cc (we are not subscribed to all lists). 2. If you see this message on a numpy/scipy list, but not on another list (could be due to a moderation queue) then please forward this message again to that other list. Thanks, Ralf

Announcing Theano 0.9.0
by Steven Bocco March 21, 2017

March 21, 2017

Announcing Theano 0.9.0 This is a release for a major version, with lots of new features, bug fixes, and some interface changes (deprecated or potentially misleading features were removed). This release is the last major version that features the old GPU back-end ( theano.sandbox.cuda, accessible through device=gpu*). All GPU users are encouraged to transition to the new GPU back-end, based on libgpuarray ( theano.gpuarray, accessible through device=cuda*). For more information, see https://github.com/Theano/Theano/wiki/Converting-to-the-new-gpu-back-end%28… . Upgrading to Theano 0.9.0 is recommended for everyone, but you should first make sure that your code does not raise deprecation warnings with Theano 0.8*. Otherwise either results can change, or warnings may have been turned into errors. For those using the bleeding edge version in the git repository, we encourage you to update to the rel-0.9.0 tag. What's New Highlights (since 0.8.0): - Better Python 3.5 support - Better numpy 1.12 support - Conda packages for Mac, Linux and Windows - Support newer Mac and Windows versions - More Windows integration: - Theano scripts (theano-cache and theano-nose) now works on Windows - Better support for Windows end-lines into C codes - Support for space in paths on Windows - Scan improvements: - More scan optimizations, with faster compilation and gradient computation - Support for checkpoint in scan (trade off between speed and memory usage, useful for long sequences) - Fixed broadcast checking in scan - Graphs improvements: - More numerical stability by default for some graphs - Better handling of corner cases for theano functions and graph optimizations - More graph optimizations with faster compilation and execution - smaller and more readable graph - New GPU back-end: - Removed warp-synchronous programming to get good results with newer CUDA drivers - More pooling support on GPU when cuDNN isn't available - Full support of ignore_border option for pooling - Inplace storage for shared variables - float16 storage - Using PCI bus ID of graphic cards for a better mapping between theano device number and nvidia-smi number - Fixed offset error in GpuIncSubtensor - Less C code compilation - Added support for bool dtype - Updated and more complete documentation - Bug fixes related to merge optimizer and shape inference - Lot of other bug fixes, crashes fixes and warning improvements Interface changes: - Merged CumsumOp/CumprodOp into CumOp - In MRG module: - Replaced method multinomial_wo_replacement() with new method choice() - Random generator now tries to infer the broadcast pattern of its output - New pooling interface - Pooling parameters can change at run time - Moved softsign out of sandbox to theano.tensor.nnet.softsign - Using floatX dtype when converting empty list/tuple - Roll make the shift be modulo the size of the axis we roll on - round() default to the same as NumPy: half_to_even Convolution updates: - Support of full and half modes for 2D and 3D convolutions including in conv3d2d - Allowed pooling of empty batch - Implement conv2d_transpose convenience function - Multi-cores convolution and pooling on CPU - New abstract 3d convolution interface similar to the 2d convolution interface - Dilated convolution GPU: - cuDNN: support versoin 5.1 and wrap batch normalization (2d and 3d) and RNN functions - Multiple-GPU, synchrone update (via platoon, use NCCL) - Gemv(matrix-vector product) speed up for special shape - cublas gemv workaround when we reduce on an axis with a dimensions size of 0 - Warn user that some cuDNN algorithms may produce unexpected results in certain environments for convolution backward filter operations - GPUMultinomialFromUniform op now supports multiple dtypes - Support for MaxAndArgMax for some axis combination - Support for solve (using cusolver), erfinv and erfcinv - Implemented GpuAdvancedSubtensor New features: - OpFromGraph now allows gradient overriding for every input - Added Abstract Ops for batch normalization that use cuDNN when available and pure Theano CPU/GPU alternatives otherwise - Added gradient of solve, tensorinv (CPU), tensorsolve (CPU), searchsorted (CPU), DownsampleFactorMaxGradGrad (CPU) - Added Multinomial Without Replacement - Allowed partial evaluation of compiled function - More Rop support - Indexing support ellipsis: a[..., 3]`, a[1,...,3] - Added theano.tensor.{tensor5,dtensor5, ...} - compiledir_format support device - Added New Theano flag conv.assert_shape to check user-provided shapes at runtime (for debugging) - Added new Theano flag cmodule.age_thresh_use - Added new Theano flag cuda.enabled - Added new Theano flag nvcc.cudafe to enable faster compilation and import with old CUDA back-end - Added new Theano flag print_global_stats to print some global statistics (time spent) at the end - Added new Theano flag profiling.ignore_first_call, useful to profile the new gpu back-end - remove ProfileMode (use Theano flag profile=True instead) Others: - Split op now has C code for CPU and GPU - theano-cache list now includes compilation times - Speed up argmax only on GPU (without also needing the max) - More stack trace in error messages - Speed up cholesky grad - log(sum(exp(...))) now get stability optimized Other more detailed changes: - Added Jenkins (gpu tests run on pull requests in addition to daily buildbot) - Removed old benchmark directory and other old files not used anymore - Use of 64-bit indexing in sparse ops to allow matrix with more then 231-1 elements - Allowed more then one output to be an destructive inplace - More support of negative axis - Added the keepdims parameter to the norm function - Make scan gradient more deterministic Download and Install You can download Theano from http://pypi.python.org/pypi/Theano Installation instructions are available at http://deeplearning.net/software/theano/install.html Description Theano is a Python library that allows you to define, optimize, and efficiently evaluate mathematical expressions involving multi-dimensional arrays. It is built on top of NumPy. Theano features: - tight integration with NumPy: a similar interface to NumPy's. numpy.ndarrays are also used internally in Theano-compiled functions. - transparent use of a GPU: perform data-intensive computations much faster than on a CPU. - efficient symbolic differentiation: Theano can compute derivatives for functions of one or many inputs. - speed and stability optimizations: avoid nasty bugs when computing expressions such as log(1+ exp(x)) for large values of x. - dynamic C code generation: evaluate expressions faster. - extensive unit-testing and self-verification: includes tools for detecting and diagnosing bugs and/or potential problems. Theano has been powering large-scale computationally intensive scientific research since 2007, but it is also approachable enough to be used in the classroom (IFT6266 at the University of Montreal).

AT&T format
by Slavin, Jonathan March 10, 2017

March 10, 2017

Have you looked at the python library struct? I don't know anything about the AT&T format but I have been able to read Fortran unformatted data using it. It depends on knowing the number of padding bytes on each line, etc. Anyways, could be useful.

Excellent. We are working with DSP32C legacy data, and of course it is not a native type. The original C code is no longer available so this is our numpy implementation... Might there be a "better" method to support the AT&T format? def dsp32c_to_float(bytes): dsp32c_array = np.frombuffer(bytes, np.int32) signed = dsp32c_array & 0x80000000 > 0 exponent = (dsp32c_array & 0x000000ff) << 23 mantissa = (dsp32c_array & 0x7fffffff) >> 8 mantissa[signed] = 0x80000000 + ~mantissa[signed] ieee_array = exponent + mantissa float_array = ieee_array.view('f') return float_array Of course if anyone out there has a stashed copy of dsptools.c void ieeetodspf( float *x); void dspftoieee( float *x); http://www.symres.com/files/legacy/mandsp.pdf it would go a long way...

ANN: SciPy 0.19.0
by Evgeni Burovski March 9, 2017

March 9, 2017

On behalf of the Scipy development team I am pleased to announce the availability of Scipy 0.19.0. This release contains several great new features and a large number of bug fixes and various improvements, as detailed in the release notes below. 121 people contributed to this release over the course of seven months. Thanks to everyone who contributed! This release requires Python 2.7 or 3.4-3.6 and NumPy 1.8.2 or greater. Source tarballs and release notes can be found at https://github.com/scipy/scipy/releases/tag/v0.19.0. OS X and Linux wheels are available from PyPI. For security-conscious, the wheels themselves are signed with my GPG key. Additionally, you can checksum the wheels and verify the checksums with those listed below or in the README file at https://github.com/scipy/scipy/releases/tag/v0.19.0. Cheers, Evgeni -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA256 ========================== SciPy 0.19.0 Release Notes ========================== .. contents:: SciPy 0.19.0 is the culmination of 7 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, which are documented below. All users are encouraged to upgrade to this release, as there are a large number of bug-fixes and optimizations. Moreover, our development attention will now shift to bug-fix releases on the 0.19.x branch, and on adding new features on the master branch. This release requires Python 2.7 or 3.4-3.6 and NumPy 1.8.2 or greater. Highlights of this release include: - - A unified foreign function interface layer, `scipy.LowLevelCallable`. - - Cython API for scalar, typed versions of the universal functions from the `scipy.special` module, via `cimport scipy.special.cython_special`. New features ============ Foreign function interface improvements - --------------------------------------- `scipy.LowLevelCallable` provides a new unified interface for wrapping low-level compiled callback functions in the Python space. It supports Cython imported "api" functions, ctypes function pointers, CFFI function pointers, ``PyCapsules``, Numba jitted functions and more. See `gh-6509 <https://github.com/scipy/scipy/pull/6509>`_ for details. `scipy.linalg` improvements - --------------------------- The function `scipy.linalg.solve` obtained two more keywords ``assume_a`` and ``transposed``. The underlying LAPACK routines are replaced with "expert" versions and now can also be used to solve symmetric, hermitian and positive definite coefficient matrices. Moreover, ill-conditioned matrices now cause a warning to be emitted with the estimated condition number information. Old ``sym_pos`` keyword is kept for backwards compatibility reasons however it is identical to using ``assume_a='pos'``. Moreover, the ``debug`` keyword, which had no function but only printing the ``overwrite_<a, b>`` values, is deprecated. The function `scipy.linalg.matrix_balance` was added to perform the so-called matrix balancing using the LAPACK xGEBAL routine family. This can be used to approximately equate the row and column norms through diagonal similarity transformations. The functions `scipy.linalg.solve_continuous_are` and `scipy.linalg.solve_discrete_are` have numerically more stable algorithms. These functions can also solve generalized algebraic matrix Riccati equations. Moreover, both gained a ``balanced`` keyword to turn balancing on and off. `scipy.spatial` improvements - ---------------------------- `scipy.spatial.SphericalVoronoi.sort_vertices_of_regions` has been re-written in Cython to improve performance. `scipy.spatial.SphericalVoronoi` can handle > 200 k points (at least 10 million) and has improved performance. The function `scipy.spatial.distance.directed_hausdorff` was added to calculate the directed Hausdorff distance. ``count_neighbors`` method of `scipy.spatial.cKDTree` gained an ability to perform weighted pair counting via the new keywords ``weights`` and ``cumulative``. See `gh-5647 <https://github.com/scipy/scipy/pull/5647>`_ for details. `scipy.spatial.distance.pdist` and `scipy.spatial.distance.cdist` now support non-double custom metrics. `scipy.ndimage` improvements - ---------------------------- The callback function C API supports PyCapsules in Python 2.7 Multidimensional filters now allow having different extrapolation modes for different axes. `scipy.optimize` improvements - ----------------------------- The `scipy.optimize.basinhopping` global minimizer obtained a new keyword, `seed`, which can be used to seed the random number generator and obtain repeatable minimizations. The keyword `sigma` in `scipy.optimize.curve_fit` was overloaded to also accept the covariance matrix of errors in the data. `scipy.signal` improvements - --------------------------- The function `scipy.signal.correlate` and `scipy.signal.convolve` have a new optional parameter `method`. The default value of `auto` estimates the fastest of two computation methods, the direct approach and the Fourier transform approach. A new function has been added to choose the convolution/correlation method, `scipy.signal.choose_conv_method` which may be appropriate if convolutions or correlations are performed on many arrays of the same size. New functions have been added to calculate complex short time fourier transforms of an input signal, and to invert the transform to recover the original signal: `scipy.signal.stft` and `scipy.signal.istft`. This implementation also fixes the previously incorrect ouput of `scipy.signal.spectrogram` when complex output data were requested. The function `scipy.signal.sosfreqz` was added to compute the frequency response from second-order sections. The function `scipy.signal.unit_impulse` was added to conveniently generate an impulse function. The function `scipy.signal.iirnotch` was added to design second-order IIR notch filters that can be used to remove a frequency component from a signal. The dual function `scipy.signal.iirpeak` was added to compute the coefficients of a second-order IIR peak (resonant) filter. The function `scipy.signal.minimum_phase` was added to convert linear-phase FIR filters to minimum phase. The functions `scipy.signal.upfirdn` and `scipy.signal.resample_poly` are now substantially faster when operating on some n-dimensional arrays when n > 1. The largest reduction in computation time is realized in cases where the size of the array is small (<1k samples or so) along the axis to be filtered. `scipy.fftpack` improvements - ---------------------------- Fast Fourier transform routines now accept `np.float16` inputs and upcast them to `np.float32`. Previously, they would raise an error. `scipy.cluster` improvements - ---------------------------- Methods ``"centroid"`` and ``"median"`` of `scipy.cluster.hierarchy.linkage` have been significantly sped up. Long-standing issues with using ``linkage`` on large input data (over 16 GB) have been resolved. `scipy.sparse` improvements - --------------------------- The functions `scipy.sparse.save_npz` and `scipy.sparse.load_npz` were added, providing simple serialization for some sparse formats. The `prune` method of classes `bsr_matrix`, `csc_matrix`, and `csr_matrix` was updated to reallocate backing arrays under certain conditions, reducing memory usage. The methods `argmin` and `argmax` were added to classes `coo_matrix`, `csc_matrix`, `csr_matrix`, and `bsr_matrix`. New function `scipy.sparse.csgraph.structural_rank` computes the structural rank of a graph with a given sparsity pattern. New function `scipy.sparse.linalg.spsolve_triangular` solves a sparse linear system with a triangular left hand side matrix. `scipy.special` improvements - ---------------------------- Scalar, typed versions of universal functions from `scipy.special` are available in the Cython space via ``cimport`` from the new module `scipy.special.cython_special`. These scalar functions can be expected to be significantly faster then the universal functions for scalar arguments. See the `scipy.special` tutorial for details. Better control over special-function errors is offered by the functions `scipy.special.geterr` and `scipy.special.seterr` and the context manager `scipy.special.errstate`. The names of orthogonal polynomial root functions have been changed to be consistent with other functions relating to orthogonal polynomials. For example, `scipy.special.j_roots` has been renamed `scipy.special.roots_jacobi` for consistency with the related functions `scipy.special.jacobi` and `scipy.special.eval_jacobi`. To preserve back-compatibility the old names have been left as aliases. Wright Omega function is implemented as `scipy.special.wrightomega`. `scipy.stats` improvements - -------------------------- The function `scipy.stats.weightedtau` was added. It provides a weighted version of Kendall's tau. New class `scipy.stats.multinomial` implements the multinomial distribution. New class `scipy.stats.rv_histogram` constructs a continuous univariate distribution with a piecewise linear CDF from a binned data sample. New class `scipy.stats.argus` implements the Argus distribution. `scipy.interpolate` improvements - -------------------------------- New class `scipy.interpolate.BSpline` represents splines. ``BSpline`` objects contain knots and coefficients and can evaluate the spline. The format is consistent with FITPACK, so that one can do, for example:: >>> t, c, k = splrep(x, y, s=0) >>> spl = BSpline(t, c, k) >>> np.allclose(spl(x), y) ``spl*`` functions, `scipy.interpolate.splev`, `scipy.interpolate.splint`, `scipy.interpolate.splder` and `scipy.interpolate.splantider`, accept both ``BSpline`` objects and ``(t, c, k)`` tuples for backwards compatibility. For multidimensional splines, ``c.ndim > 1``, ``BSpline`` objects are consistent with piecewise polynomials, `scipy.interpolate.PPoly`. This means that ``BSpline`` objects are not immediately consistent with `scipy.interpolate.splprep`, and one *cannot* do ``>>> BSpline(*splprep([x, y])[0])``. Consult the `scipy.interpolate` test suite for examples of the precise equivalence. In new code, prefer using ``scipy.interpolate.BSpline`` objects instead of manipulating ``(t, c, k)`` tuples directly. New function `scipy.interpolate.make_interp_spline` constructs an interpolating spline given data points and boundary conditions. New function `scipy.interpolate.make_lsq_spline` constructs a least-squares spline approximation given data points. `scipy.integrate` improvements - ------------------------------ Now `scipy.integrate.fixed_quad` supports vector-valued functions. Deprecated features =================== `scipy.interpolate.splmake`, `scipy.interpolate.spleval` and `scipy.interpolate.spline` are deprecated. The format used by `splmake/spleval` was inconsistent with `splrep/splev` which was confusing to users. `scipy.special.errprint` is deprecated. Improved functionality is available in `scipy.special.seterr`. calling `scipy.spatial.distance.pdist` or `scipy.spatial.distance.cdist` with arguments not needed by the chosen metric is deprecated. Also, metrics `"old_cosine"` and `"old_cos"` are deprecated. Backwards incompatible changes ============================== The deprecated ``scipy.weave`` submodule was removed. `scipy.spatial.distance.squareform` now returns arrays of the same dtype as the input, instead of always float64. `scipy.special.errprint` now returns a boolean. The function `scipy.signal.find_peaks_cwt` now returns an array instead of a list. `scipy.stats.kendalltau` now computes the correct p-value in case the input contains ties. The p-value is also identical to that computed by `scipy.stats.mstats.kendalltau` and by R. If the input does not contain ties there is no change w.r.t. the previous implementation. The function `scipy.linalg.block_diag` will not ignore zero-sized matrices anymore. Instead it will insert rows or columns of zeros of the appropriate size. See gh-4908 for more details. Other changes ============= SciPy wheels will now report their dependency on ``numpy`` on all platforms. This change was made because Numpy wheels are available, and because the pip upgrade behavior is finally changing for the better (use ``--upgrade-strategy=only-if-needed`` for ``pip >= 8.2``; that behavior will become the default in the next major version of ``pip``). Numerical values returned by `scipy.interpolate.interp1d` with ``kind="cubic"`` and ``"quadratic"`` may change relative to previous scipy versions. If your code depended on specific numeric values (i.e., on implementation details of the interpolators), you may want to double-check your results.

Re: [SciPy-User] [numfocus] Docathon : focus on documentation on your favorite opensource project!
by Ralf Gommers March 8, 2017

March 8, 2017

This is awesome, so I've taken the liberty of signing SciPy up. Reminds me of the NumPy & SciPy Documentation Marathon - that's how I got started contributing 9 years ago. Next week is pretty poor timing for me, but I'm going to get at least 1 PR in and review as many as I can. There's no specific site or issues marked for this docathon, but it's easy to participate. It's just a matter of finding functions with incomplete documentation (that's not hard ....) - adding a usage example can be a major improvement already.
