25 Apr '18

=========================== Announcing PyTables 3.4.3 =========================== We are happy to announce PyTables 3.4.3 What's new ========== This new release of PyTables gets support of `hfile.root['some child']` dict-like syntax for accessing children. There is also support for `new os.fspath` method (PEP 519). The release includes many small bugfixes. In case you want to know more in detail what has changed in this version, please refer to:http://www.pytables.org/release_notes.html You can install it via pip or download a source package with generated PDF and HTML docs from: https://github.com/PyTables/PyTables/releases/v3.4.3 For an online version of the manual, visit: http://www.pytables.org/usersguide/index.html What it is? =========== PyTables is a library for managing hierarchical datasets and designed to efficiently cope with extremely large amounts of data with support for full 64-bit file addressing. PyTables runs on top of the HDF5 library and NumPy package for achieving maximum throughput and convenient use. PyTables includes OPSI, a new indexing technology, allowing to perform data lookups in tables exceeding 10 gigarows (10**10 rows) in less than a tenth of a second. Resources ========= About PyTables:http://www.pytables.org About the HDF5 library:http://hdfgroup.org/HDF5/ About NumPy:http://numpy.scipy.org/ Acknowledgments =============== Thanks to many users who provided feature improvements, patches, bug reports, support and suggestions. See the ``THANKS`` file in the distribution package for a (incomplete) list of contributors. Most specially, a lot of kudos go to the HDF5 and NumPy makers. Without them, PyTables simply would not exist. Share your experience ===================== Let us know of any bugs, suggestions, gripes, kudos, etc. you may have. ---- **Enjoy data!** -- The PyTables Developers

User research on the new PyPI
by Nicole Harris 24 Apr '18

24 Apr '18

Following the release of the new PyPI, the development team continues to look for ways to improve the site - this includes conducting user research and user testing to better understand what the Python community needs from the user interface. Our initial focus will be on redesigning the main project page (e.g. https://pypi.org/project/pip/), as this is the most visited page on the website. Yesterday, we launched a small user research exercise that asks Python developers to "buy a feature" on this page, to help us understand what is important to them. So far, we have received 112 responses, but it would be great to have more. If you have not already done so, please consider participating here: https://t.co/aYpp2ve2iY The exercise takes around 5 minutes. In addition, we would appreciate if you could spread the word about this exercise to reach the greatest number of PyPI users. For those on Twitter, we have a handy tweet set up: https://twitter.com/intent/tweet?hashtags=python%2Cpypi&ref_src=twsrc%5Etfw… Or you can retweet https://twitter.com/nlhkabu/status/988856279526465537 Many thanks, *Nicole Harris* PyPA member, Lead Designer - Warehouse Project

Pythran 0.8.5
by Serge Guelton 24 Apr '18

24 Apr '18

(sorry for the double posting if any) It is my pleasure to announce a new version of the Pythran compiler. Pythran is an Ahead of Time compiler for a subset of the Python language, with a focus on scientific kernels. It can turn code like the one below: #pythran export weights(uint8[:,:]) import numpy as np def weights(input_data, threshold=0.3): n_seq, length = input_data.shape weights = np.zeros(n_seq, dtype=np.float32) for i in range(n_seq): vector = input_data[i, None, :] count_matches = np.sum(vector == input_data, axis=1) over_threshold = count_matches > (threshold * length) total = np.sum(over_threshold) weights[i] = 1 / total return weights into a native module that runs roughly 10 times faster than when interpreted by cpython. It's available on PyPi, Conda and GitHub under BSD license. For the curious reader, the Changelog is reproduced below. It's a megablast! ---- 2018-04-23 Serge Guelton <serge.guelton(a)telecom-bretagne.eu> - numpy.fft support (thanks to Jean Laroche) - Faster generalized expression - Faster numpy.transpose, numpy.argmax, numpy reduction - Sphinx-compatible generated docstring (thanks to Pierre Augier) - Python output through -P (thanks to Pierre Augier) - Many bugfixes and numpy improvements (thanks to Yann Diorecet and Jean Laroche)

Pip 10.0.1 has been released
by Paul Moore 19 Apr '18

19 Apr '18

On behalf of the PyPA, I am pleased to announce that pip 10.0.1 has just been released. This release fixes a number of issues with the initial release of pip 10.0, notably: * A problem with running the "pip.exe" wrapper script on Windows from a directory with a space in the name. * A problem with get-pip.py needing to be renamed on Windows to avoid triggering a check in pip that aborts the run. * A problem with build isolation when pip is installed as --user * An issue with the vendored msgpack library on older versions of Python 2.7 * A problem with pip installing from non-editable VCS URLs Thanks to all the people who reported issues and helped with the fixes.

PyCon ZA 2018 - Call for Speakers
by Neil Muller 19 Apr '18

19 Apr '18

PyCon ZA 2018 will take place on the 11th & 12th of October at The Birchwood Hotel & Conference Centre, in Boksburg North, Johannesburg, South Africa (location link: https://goo.gl/maps/XMtwhJCKVt92 ). There will also be tutorial sessions the day before the conference (the 10th) and we will hold sprints on the 13th & 14th of October. We are currently accepting proposals for talks. If you would like to give a presentation, please register at https://za.pycon.org/ and submit your proposal, following the instructions at https://za.pycon.org/talks/submit-talk . We have a number of tracks available, including: Web, Scientific-Computing/PyData, Testing and Other (which includes all talks that don't fall under the mentioned tracks). We hope to notify accepted presenters by no later than the 31st of August 2018. The presentation slots will be 30 minutes long, with an additional 10 minutes for discussion at the end. Shared sessions are also possible. The presentations will be in English. PyCon ZA offers a mentorship program for inexperienced speakers. If you would like assistance preparing your submission, email team(a)za.pycon.org with a rough draft of your talk proposal and we'll find a suitable experienced speaker to act as a mentor. In addition to talks, we are also looking for proposals for tutorials, demos, sprints and open spaces. Tutorials will be held before the conference and are expected to provided in-depth coverage of a topic. The number of attendees will be also be limited. We are accepting proposals for either half-day (4 hours) or full-day (8 hours) tutorials. We hope to notify accepted tutorial presenters by no later than the 27th of July 2018. Demos are cool things for attendees to see and interact with. Open spaces are open discussion forums where communities with a common interest gather to present views, ask questions and meet people interested in the topic. Sprints are coding efforts and hack days that happen after the conference. There is no need to register a sprint or open space topic upfront, but doing so allows us to advertise them during the conference. Financial assistance for attendees is available at: https://za.pycon.org/financial-aid/ and will be reviewed on a case-by-case basis. -- Neil Muller On behalf of the PyCon ZA organising committee

by Vinay Sajip 16 Apr '18

16 Apr '18

I've just released version 0.2.7 of distlib on PyPI [1]. For newcomers, distlib is a library of packaging functionality which is intended to be usable as the basis for third-party packaging tools. The main changes in this release are as follows: * Addressed #102: InstalledDistributions now have a modules attribute which is a list of top-level modules as read from top_level.txt, if that is in the distribution info. * Fixed #103: Now https downloads are preferred to those over http. Thanks to Saulius Žemaitaitis for the patch. * Fixed #104: Updated launcher binaries to properly handle interpreter paths with spaces. Thanks to Atsushi Odagiri for the diagnosis and fix. * Fixed #105: cache_from_source is now imported from importlib.util where available. * Added support for PEP 566 / Metadata 2.1. A more detailed change log is available at [2]. Please try it out, and if you find any problems or have any suggestions for improvements, please give some feedback using the issue tracker!
