[baseline 0.2.1] Easy String Baseline
by Dan Gass 30 Mar '20

30 Mar '20

I am please to announce the availability of the "baseline" package. This tool streamlines creation and maintenance of tests which compare string output against a baseline. It offers a mechanism to compare a string against a baselined copy and update the baselined copy to match the new value when a mismatch occurs. The update process includes a manual step to facilitate a review of the change before acceptance. The tool uses multi-line string format for string baselines to improve readability for human review. Docs: https://baseline.readthedocs.io/en/latest/ PyPi: https://pypi.org/project/baseline/ Repo: https://github.com/dmgass/baseline License: MIT With Regards, Dan Gass (dan.gass at gmail) *********** Quick Start *********** Create an empty baseline with a triple quoted multi-line string. Place the ending triple quote on a separate line and indent it to the level you wish the string baseline update to be indented to. Add a compare of the string being tested to the baseline string. Then save the file as ``fox.py``: .. code-block:: python from baseline import Baseline expected = Baseline(""" """) test_string = "THE QUICK BROWN FOX\n JUMPS\nOVER THE LAZY DOG." assert test_string == expected Run ``fox.py`` and observe that the ``assert`` raises an exception since the strings are not equal. Because the comparison failed, the tool located the triple quoted baseline string in the source file and updated it with the miscompared value. When the interpretter exited, the tool saved the updated source file but changed the file name to ``fox.update.py``: .. code-block:: python from baseline import Baseline expected = Baseline(""" THE QUICK BROWN FOX JUMPS OVER THE LAZY DOG. """) test_string = "THE QUICK BROWN FOX\n JUMPS\nOVER THE LAZY DOG." assert test_string == expected After reviewing the change with your favorite file differencing tool, accept the change by either manually overwriting the original file or use the ``baseline`` command line tool to scan the directory for updated scripts and accept them: .. code-block:: shell $ python -m baseline * Found updates for: fox.py Hit [ENTER] to update, [Ctrl-C] to cancel fox.update.py -> fox.py Run ``fox.py`` again and observe the ``assert`` does not raise an exception nor is a source file update generated. If in the future the test value changes, the ``assert`` will raise an exception and cause a new source file update to be generated. Simply repeat the review and acceptance step and you are back in business! <P><A HREF="https://baseline.readthedocs.io/en/latest/"> baseline 0.2.1</A> - Easy String Baseline (07-Jun-18)

ANN: PyWavelets 1.0.0
by Gregory Lee 31 Aug '18

31 Aug '18

Hello all, We are pleased to announce the release of PyWavelets 1.0. We view this version number as a milestone in the project's now more than a decade long history. It reflects that PyWavelets has stabilized over the past few years, and is now a mature package which a lot of other important packages depend on. A listing of those package won't be complete, but some we are aware of are: - `scikit-image <https://scikit-image.org>`_ - image processing in Python - `imagehash <https://github.com/JohannesBuchner/imagehash>`_ - perceptual image hashing - `pyradiomics <https://github.com/Radiomics/pyradiomics>`_ - extraction of Radiomics features from 2D and 3D images and binary masks - `tomopy <https://github.com/tomopy/tomopy>`_ - Tomographic Reconstruction in Python - `SpikeSort <https://github.com/btel/SpikeSort>`_ - Spike sorting library implemented in Python/NumPy/PyTables - `ODL <https://github.com/odlgroup/odl>`_ - operator discretization library This release requires Python 2.7 or >=3.5 and NumPy 1.9.1 or greater. The 1.0 release will be the last release supporting Python 2.7. It will be a Long Term Support (LTS) release, meaning that we will backport critical bug fixes to 1.0.x for as long as Python itself does so (i.e. until 1 Jan 2020). A summary of new features and lists of specific issues and pull requests closed is available in the full release notes at: https://github.com/PyWavelets/pywt/blob/master/doc/release/1.0.0-notes.rst Authors ======= * 0-tree + * Jacopo Antonello + * Matthew Brett + * Saket Choudhary + * Michael V. DePalatis + * Daniel Goertzen + * Ralf Gommers * Mark Harfouche + * John Kirkham + * Dawid Laszuk + * Gregory R. Lee * Michel Pelletier + * Balint Reczey + * SylvainLan + * Daniele Tricoli * Kai Wohlfahrt A total of 16 people contributed to this release. People with a "+" by their names contributed a patch for the first time. This list of names is automatically generated, and may not be fully complete.

NumPy 1.15.1 released.
by Charles R Harris 21 Aug '18

21 Aug '18

Hi All, On behalf of the NumPy team, I am pleased to announce the release of NumPy 1.15.1. This is a bugfix release for bugs and regressions reported following the 1.15.0 release. Noticeable fixes are - The annoying but harmless RuntimeWarning that "numpy.dtype size changed" has been suppressed. The long standing suppression was lost in the transition to pytest. - The update to Cython 0.28.3 exposed a problematic use of a gcc attribute used to prefer code size over speed in module initialization, possibly resulting in incorrect compiled code. This has been fixed in latest Cython but has been disabled here for safety. - Support for big-endian and ARMv8 architectures has been improved. The Python versions supported by this release are 2.7, 3.4-3.7. The wheels are linked with OpenBLAS v0.3.0, which should fix some of the linalg problems reported for NumPy 1.14. Wheels for this release can be downloaded from PyPI <https://pypi.org/project/numpy/1.15.1/>, source archives are available from Github <https://github.com/numpy/numpy/releases/tag/v1.15.1>. *Compatibility Note* The NumPy 1.15.x OS X wheels released on PyPI no longer contain 32-bit binaries. That will also be the case in future releases. See #11625 <https://github.com/numpy/numpy/issues/11625> for the related discussion. Those needing 32-bit support on the Mac should look elsewhere or build from source. *Contributors* A total of 7 people contributed to this release. People with a "+" by their names contributed a patch for the first time. * Charles Harris * Chris Billington * Elliott Sales de Andrade + * Eric Wieser * Jeremy Manning + * Matti Picus * Ralf Gommers *Pull requests merged* A total of 24 pull requests were merged for this release. * `#11647 <https://github.com/numpy/numpy/pull/11647>`__: MAINT: Filter Cython warnings in ``__init__.py`` * `#11648 <https://github.com/numpy/numpy/pull/11648>`__: BUG: Fix doc source links to unwrap decorators * `#11657 <https://github.com/numpy/numpy/pull/11657>`__: BUG: Ensure singleton dimensions are not dropped when converting... * `#11661 <https://github.com/numpy/numpy/pull/11661>`__: BUG: Warn on Nan in minimum,maximum for scalars * `#11665 <https://github.com/numpy/numpy/pull/11665>`__: BUG: cython sometimes emits invalid gcc attribute * `#11682 <https://github.com/numpy/numpy/pull/11682>`__: BUG: Fix regression in void_getitem * `#11698 <https://github.com/numpy/numpy/pull/11698>`__: BUG: Make matrix_power again work for object arrays. * `#11700 <https://github.com/numpy/numpy/pull/11700>`__: BUG: Add missing PyErr_NoMemory after failing malloc * `#11719 <https://github.com/numpy/numpy/pull/11719>`__: BUG: Fix undefined functions on big-endian systems. * `#11720 <https://github.com/numpy/numpy/pull/11720>`__: MAINT: Make einsum optimize default to False. * `#11746 <https://github.com/numpy/numpy/pull/11746>`__: BUG: Fix regression in loadtxt for bz2 text files in Python 2. * `#11757 <https://github.com/numpy/numpy/pull/11757>`__: BUG: Revert use of `console_scripts`. * `#11758 <https://github.com/numpy/numpy/pull/11758>`__: BUG: Fix Fortran kind detection for aarch64 & s390x. * `#11759 <https://github.com/numpy/numpy/pull/11759>`__: BUG: Fix printing of longdouble on ppc64le. * `#11760 <https://github.com/numpy/numpy/pull/11760>`__: BUG: Fixes for unicode field names in Python 2 * `#11761 <https://github.com/numpy/numpy/pull/11761>`__: BUG: Increase required cython version on python 3.7 * `#11763 <https://github.com/numpy/numpy/pull/11763>`__: BUG: check return value of _buffer_format_string * `#11775 <https://github.com/numpy/numpy/pull/11775>`__: MAINT: Make assert_array_compare more generic. * `#11776 <https://github.com/numpy/numpy/pull/11776>`__: TST: Fix urlopen stubbing. * `#11777 <https://github.com/numpy/numpy/pull/11777>`__: BUG: Fix regression in intersect1d. * `#11779 <https://github.com/numpy/numpy/pull/11779>`__: BUG: Fix test sensitive to platform byte order. * `#11781 <https://github.com/numpy/numpy/pull/11781>`__: BUG: Avoid signed overflow in histogram * `#11785 <https://github.com/numpy/numpy/pull/11785>`__: BUG: Fix pickle and memoryview for datetime64, timedelta64 scalars * `#11786 <https://github.com/numpy/numpy/pull/11786>`__: BUG: Deprecation triggers segfault Cheers, Charles Harris
