Official PyPI vs unofficial binaries

Is there any point of installing packages from unofficial binaries (https://www.lfd.uci.edu/

gohlke/pythonlibs/) if the official PyPI doesn’t give me issues? I installed numpy+mkl from there because intel-numpy wasn’t available for my Python version, but I don’t know the difference for scipy and other packages. Do any of them come with optimizations not available on the official repositories?

1 Answer 1

I emailed the maintainer of that page and got the following responses:

1. Which of the other packages are linked with MKL? Is it everything that says «Install numpy+mkl before installing scipy.» or is that just a generic numpy dependency declaration?

Numpy+mkl contains Intel MKL, Fortran, C, DAAL, TBB, and OpenBLAS runtime DLLs needed by other packages that are compiled with one of those. I don’t have a list of which packages are using which of those. You can probably get most packages working without numpy-mkl by installing the runtime DLLs manually.

1. In the case of scipy, intel also has intel-scipy compiled with MKL optimizations; is that similar to yours?

I think the Intel Python distribution is compiled with Intel compiler instead of MSVC and also replaces some function of certain packages (numpy, scipy, scikit-learn) with their own optimized functions. I don’t know for sure.

1. As a rule of thumb, if I want performance without having to install intel python distribution, which packages should I get from your site and which ones should I get from regular pip?

Probably numpy+mkl and scipy. MKL_fft and numexpr are also nice. However the official numpy and scipy binaries are using OpenBLAS, which is actually faster on AMD CPUs.

Licenses

All Python releases are Open Source. Historically, most, but not all, Python releases have also been GPL-compatible. The Licenses page details GPL-compatibility and Terms and Conditions.

Sources

For most Unix systems, you must download and compile the source code. The same source code archive can also be used to build the Windows and Mac versions, and is the starting point for ports to all other platforms.

Download the latest Python 3 and Python 2 source.

Alternative Implementations

This site hosts the «traditional» implementation of Python (nicknamed CPython). A number of alternative implementations are available as well.

History

Python was created in the early 1990s by Guido van Rossum at Stichting Mathematisch Centrum in the Netherlands as a successor of a language called ABC. Guido remains Python’s principal author, although it includes many contributions from others.

Release Schedules

Information about specific ports, and developer info

OpenPGP Public Keys

Source and binary executables are signed by the release manager or binary builder using their OpenPGP key. Release files for currently supported releases are signed by the following:

Release files for older releases which have now reached end-of-life may have been signed by one of the following:

• Anthony Baxter (key id: 0EDD C5F2 6A45 C816)
• Georg Brandl (key id: 0A5B 1018 3658 0288)
• Martin v. Löwis (key id: 6AF0 53F0 7D9D C8D2)
• Ronald Oussoren (key id: C9BE 28DE E6DF 025C)
• Barry Warsaw (key ids: 126E B563 A74B 06BF, D986 6941 EA5B BD71, and ED9D77D5)

You can import a person’s public keys from a public keyserver network server you trust by running a command like:

or, in many cases, public keys can also be found at keybase.io. On the version-specific download pages, you should see a link to both the downloadable file and a detached signature file. To verify the authenticity of the download, grab both files and then run this command:

Note that you must use the name of the signature file, and you should use the one that’s appropriate to the download you’re verifying.

• (These instructions are geared to GnuPG and Unix command-line users.)

Other Useful Items

• Looking for 3rd party Python modules? The Package Index has many of them.
• You can view the standard documentation online, or you can download it in HTML, PostScript, PDF and other formats. See the main Documentation page.
• Information on tools for unpacking archive files provided on python.org is available.
• Tip: even if you download a ready-made binary for your platform, it makes sense to also download the source. This lets you browse the standard library (the subdirectory Lib) and the standard collections of demos (Demo) and tools (Tools) that come with it. There’s a lot you can learn from the source!
• There is also a collection of Emacs packages that the Emacsing Pythoneer might find useful. This includes major modes for editing Python, C, C++, Java, etc., Python debugger interfaces and more. Most packages are compatible with Emacs and XEmacs.
