Description iamtomgeorgeampiath 2020-09-04 10:28:22 UTC
Created attachment 1713760 [details]
Attachment shows pip takes too much time to install dependecies for matplotlib

Description of problem:

Version-Release number of selected component (if applicable): python 3.9, pip 20.2.2

How reproducible:
Can be easily reproduced

Steps to Reproduce:
1.python -m venv venv
2.source venv/bin/activate
3.pip install numpy matplotlb

Actual results:
pip, after obtaining wheel, takes some time to prepare wheel metadata for numpy and takes forever to obtain dependencies for matplotlib. pip on python 3.8 works normally.

Expected results:
pip should not take so long to install the python packages after their wheel has been attained

Comment 1 Miro Hrončok 2020-09-04 10:40:21 UTC
There is nothing to do from our point. Contact numpy and matplotlib upstreams to publish wheels for Python 3.9.

Comment 2 Victor Stinner 2020-09-04 16:23:34 UTC
Python 3.9.0 final is not released yet, so numpy doesn't provide prebuilt packaged at PyPI.

You can see the prebuilt Python 3.8 binary package for Linux if you search for "cp38-manylinux1_x86_64" at https://pypi.org/project/numpy/#files

But there is not prebuilt package for "cp39".

Just until until Python 3.9 final is released *and* numpy releases a new version with prebuilt package for Python 3.9.

Comment 3 Miro Hrončok 2020-09-16 12:26:38 UTC
Let's wait for Python 3.9.0 final and encourage upstreams to release Python 3.9 manylinux wheels as soon as possible, ideally before Fedora 33 GA.

Other projects to ask:

For matplotlib:


For Jupyter Notebook:

MarkupSafe (done \o/)
cffi (done \o/)

Pandas in progress: https://github.com/pandas-dev/pandas/issues/36186

Comment 8 Lumír Balhar 2020-10-07 10:54:31 UTC
For scipy, users already started reporting issues: https://github.com/scipy/scipy/issues/12923

Pillow already tracks support for 3.9: https://github.com/python-pillow/Pillow/issues/4953

Comment 13 Miro Hrončok 2020-10-26 18:13:10 UTC
Projects with cp39 manylinux wheels:

- cython (also has "pure python" wheels)
- pillow
- pyzmq

Still not available:

- numpy 
- kiwisolver
- matplotlib
- pandas

The Fedora 33 release is "now" so I guess we have failed in our endeavour.

We can either repurpose this to say "ASAP" instead of "before Fedora 33 GA" or close it as CANTFIX :(

Comment 15 Miro Hrončok 2020-10-27 10:16:39 UTC
This bugzilla is named "Encourage upstreams to release Python 3.9 manylinux wheels before Fedora 33 GA" -- this can no longer happen. So my idea was to either close it or to rename (repurpose) it to "Encourage upstreams to release Python 3.9 manylinux wheels ASAP after Fedora 33 GA".

Comment 16 Petr Viktorin (pviktori) 2020-10-29 08:58:02 UTC
Alright, changing.

Numpy and kiwisolver wheels are released, so that leaves:
- matplotlib
- pandas

Comment 17 Lumír Balhar 2020-11-02 07:43:27 UTC
✅ pandas
… matplotlib

Comment 18 Lumír Balhar 2020-11-09 07:11:08 UTC
✅ scipy

Comment 19 Miro Hrončok 2020-11-10 10:17:08 UTC
Hey Elliott, could you please help us get the matplotlib Python 3.9 wheels released? It seems that the issue was closed: https://github.com/matplotlib/matplotlib/issues/18677

Comment 20 Elliott Sales de Andrade 2020-11-12 06:38:04 UTC
Matplotlib 3.3.3 is out with 3.9 wheels.
