Binary wheels for Python 3.9

[amotl]

Dear @mikeboers and @jlaine,

first things first: Thanks a stack for conceiving and maintaining the excellent PyAV package.

It recently came to our attention that there are no binary wheels for Python 3.9 available on PyPI yet [1]. While I don't know what it would take to build and publish them, I am humbly asking if you could do something about this in order to improve the situation for downstream users like outlined at ambianic/peerjs-python#48.

As I recognized you are already using cibuildwheel within your GHA recipe, it might be feasible to expand the Python version into a matrix there?

PyAV/.github/workflows/tests.yml

Lines 210 to 212 in 5d73160

	- uses: actions/setup-python@v1
	with:
	python-version: 3.7

Thanks already for looking into this and keep up the spirit!

With kind regards,
Andreas.

I use Python 3.9.1 for my AMD64 VS Code, and I recently succeeded pip install av but when importing av ImportError: DLL load failed while importing _core occurred. When installing av, pip used av-8.0.2-cp39-cp39-win_amd64.whl but I also see that there are no binary wheels for Python 3.9 available on PyPI yet, as @amotl kindly noted. May I ask whether should I downgrade Python to 3.8, or is this error happening independently with my Python version?

I am very curious about what actually av-8.0.2-cp39-cp39-win_amd64.whl is.

Dear Juyoung,

I use Python 3.9.1 for my AMD64 VS Code, and I recently succeeded pip install av but when importing av ImportError: DLL load failed while importing _core occurred.

While the installation of the package apparently succeeded (at least it looks like it has been able to crate a wheel archive), the error message clearly shows that the chances are high that the build process did not succeed (on your Windows machine?).

May I ask whether should I downgrade Python to 3.8, or is this error happening independently with my Python version?

I believe you will be definitively be better off with Python 3.8, as there are corresponding av-8.0.2-cp38-cp38-win32.whl and av-8.0.2-cp38-cp38-win_amd64.whl packages on PyPI.

With kind regards,
Andreas.

Dear Andreas,

Special thanks to your kind reply! Definitely will try that.

Best wishes,

Hi there,

I see that the release of PyAV 8.0.3 [1], published on Jan 23, 2021, now offers binary wheels for Python 3.9. So, I am closing this. Thanks a stack!

With kind regards,
Andreas.

Thanks for closing the issue @amotl I hadn't spotted it when I cut the release!
