Python 3.9 Support #828

Closed reinecke closed 3 years ago

reinecke commented 4 years ago

There currently exists a rare crash condition that can occur with the combination of python 3.9.0 and pybind11 (for context see this ASWF thread or this pybind11 issue.

The tl;dr: There could be unexpected and unpredictable crashing in Python 3.9.0, this issue is set to be addressed in 3.9.1. After 3.9.1 is released we should enable CI for 3.9 and consider adding 3.9 to the badge in the readme.

We may also consider updating the python_requires to exclude 3.9.0, though we'd want to make sure we can do this in a way that signals to users why this is and steps to remedy (use 3.9.1 instead).

ssteinbach commented 3 years ago

It looks like 3.9.1 is released: https://www.python.org/downloads/release/python-391/

I'm not sure about how the python_requires works, but I know we do some manual checks at the top of the setup.py to guard against ancient pip/setuptools versions.

ssteinbach commented 3 years ago

Note that there are a bunch of build warnings we'll need to tackle in 3.9:

src/deps/pybind11/include/pybind11/detail/internals.h:200:9: warning: 'PyEval_InitThreads' is deprecated [-Wdeprecated-declarations]
        PyEval_InitThreads();
        ^
meshula commented 3 years ago

That looks like motivation to get pybind11 updated

ssteinbach commented 3 years ago

yeah, hoping that addresses this issue. Note that pybind11 is also seeing some weird CI failure: #874

I don't know if it's completely relevant, but I've tried both the current master and the reinecke's feature/wheel-builds branch with Python3.9 and I get this error when importing:

>>> import opentimelineio
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "C:\Users\Felix\AppData\Local\Programs\Python\Python39\lib\site-packages\opentimelineio\__init__.py", line 35, in <module>

    from . _otio import ( # noqa
ImportError: DLL load failed while importing _otio: A dynamic link library (DLL) initialization routine failed.

The funny thing is, I only get this error on my personal windows computer.

On my OSX and Windows at work, I get:

I've tried to investigate, without any success until now...

Everything works fine on Python<3.9

Tilix4 commented 3 years ago

After some new experimentation, it seems no any opentimelineio version work on Python3.9, they all raise the ModuleNotFoundError: No module named 'opentimelineio._opentime' error.

vdtoorn commented 3 years ago

I get the same error on python 3.8

meshula commented 3 years ago

Separating out mac and windows for a second, is it possible we are being hit, on Windows, with the new platform specific dll search behavior? https://docs.python.org/3/library/os.html#os.add_dll_directory

If the _opentime.dll and .pyd files are in the same directory as the init.py that invokes them, could you try adding a call to add_dll_directory to init.py before the line of code that imports _opentime?

Perhaps we can come back to the mac after the issue with the windows wheel is resolved.

Tilix4 commented 3 years ago

Some inputs about that: I'm trying to install OTIO into Blender 2.93's Python, which uses python 3.9.2. Tested on MacOS and windows.

It doesn't work and I get this error:

  ERROR: Failed building wheel for OpenTimelineIO
Failed to build OpenTimelineIO
ERROR: Could not build wheels for OpenTimelineIO which use PEP 517 and cannot be installed directly

While installing it into a locally installed Python 3.9.2 works.

Tilix4 commented 3 years ago

After some new experimentation, it seems no any opentimelineio version work on Python3.9, they all raise the ModuleNotFoundError: No module named 'opentimelineio._opentime' error.

I must precise I don't get this issue any more. Then the problem to address seems to be on the build stage only and not at the import opentimelineio one.
To confirm this behaviour, I installed OTIO into Blender's site-packages using the local python 3.9.2 and the import works perfectly.

JeanChristopheMorinPerso commented 3 years ago

is it possible we are being hit, on Windows, with the new platform specific dll search behavior?

@meshula I've tried OTIO with python 3.9 a couple of times on Windows and it was working from what I remember.

As for the other platforms, I haven't seen any problem lately when building with Python 3.9.1+.

Python headers will be included into Blender's build: https://developer.blender.org/D12228

That's nice to see!
