[Python-modules-team] Bug#947069: pip does not handle manylinux2010 tag (PEP571)

[Gabriel Corona]

Package: python3-pip
Version: 18.1-5
Severity: normal

Dear Maintainer,

The pip package as installed by python3-pip refuses to install
manylinux2010 wheels (see PEP 571).

Example :

$ /usr/bin/python3.7m -m venv test.venv && . ./test.venv/bin/activate && 
pip install -vvv tensorflow==2.0.0

(from https://pypi.org/simple/tensorflow/); it is not compatible with 
this Python

The reason is that it does not know it is compatible with this
platform tag. By downloading the package manually and renaming it,
you can actually install the package:

$ mv tensorflow-2.0.0-cp37-cp37m-manylinux2010_x86_64.whl 
tensorflow-2.0.0-cp37-cp37m-manylinux1_x86_64.whl
$ pip install tensorflow-2.0.0-cp37-cp37m-manylinux1_x86_64.whl

Updating the version of pip in the venv fixes the issue:

$ pip install pip==19.3.1

Creating the virtual environment with virtualenv fixes the problem as
well because it installs a recent version of pip.

Patching python3-pip in order to support the manylinux2010 tag would
probably be very helpful:

- arches = [arch.replace('linux', 'manylinux1'), arch]
+ arches = [arch.replace('linux', 'manylinux1'), arch.replace('linux', 
'manylinux2010'), arch]
