Can pip list its binary wheels?

Question

I'm trying resolve a behavior difference between two python installations that are usually deterministic and have the same python pip packages installed.

I suspect different .so files. Is there a why to see which binaries binary wheels pip has installed, and for which architectures?

Update --

% pip show Name: scipy Version: 1.0.0rc1 Summary: SciPy: Scientific Library for Python Home-page: https://www.scipy.org Author: SciPy Developers Author-email: [email protected] License: BSD Location: /usr/local/lib/python2.7/dist-packages Requires: numpy

The above package depends on things like libopenblas which must be compiled. I'm not sure if pip used the system installation, or compiled BLAS during a pip install, or used as precompiled version of BLAS for a i386, or i686 -- who knows.

The above case I have:

/usr/local/lib/python2.7/dist-packages/scipy/.libs/libopenblasp-r0-39a31c03.2.18.so

I'd like to see which package have differences in their installed .sos in difference systems.

The information is there, but you'll have to dig around in dist-info and/or egg-info subdirectories to find it.

• Binary distributions include a RECORD file in their metadata subdirectory.
• Source distributions include an installed-files.txt file in their metadata subdirectory.

The RECORD files are csv lines of (path, hash, size) as documented in PEP-376. The older installed-files.txt from an egg is just the filenames, and you'll have to stat those files manually.

As a simple example, I have source and binary distributions of my package copyingmock available on PyPI. With the binary distribution installed (pip install copyingmock):

$ pip show --files copyingmock

Then forcing to reinstall with the source distribution (pip uninstall copyingmock and then pip install --no-binary=copyingmock copyingmock):

$ pip show --files copyingmock
