Support for Python 3.10?

[werwack]

Feature Request

Is this a New Feature, or a Proposed Change to existing Behavior?
This is the continuity of existing feature.

Description

Describe the new feature, or describe the modification to existing behavior, and provide context as necessary to help with understanding how the feature relates to a workflow or functionality.
I am the developer of Shot Manager, a Blender add-on that provides many features to manipulate shots in the 3D space of Blender but also to import and export edits with other software. To do so I rely on OpenTimelineIO.
Thing is Blender is changing regularly (or irregularly I should say) the version of Python they support, this in order to stick to the latest version. An in March Blender 3.1 will be on Python 3.10.

Would it be possible to have a version of OTIO for Python 3.10? That would be of a great help!
Thank you

Your Shot Manager project looks very cool!

If I'm not mistaken, your team is building OpenTimelineIO locally, rather than using a wheel. Is that correct? I notice also in your FAQ that it says you are working on getting a Mac build of OTIO working for Python 3.9. (https://ubisoft-shotmanager.readthedocs.io/en/latest/troubleshoot/faq.html)

I did a test build just now on Mac M1, with Python 3.10, and didn't encounter a problem

Perhaps the thing to do is to list the issues you are encountering here to work through, and if any of them require extra attention, new issues could be opened to track them individually?

Hi Meshula,
Thanks for your interest in Shot Manager and your test on Python 3.10.

In fact we are not building our wheel anymore. We did that for OTIO 0.12 cause we had a fix to do somewhere (I don't remember what, it was made by a developer of the team at the time) and for OTIO 0.13 cause there was no wheel for Python 3.9 when Blender moved to it. I also had to drop off the wheel for Mac cause I have no practical means to test it (no Mac :D )
So currently we are using the existing wheel for 3.9.

I am not so much at ease myself with the versions of Python and libraries and wheels. What I know though is that installing OTIO thanks to PIP is pretty handful and when there is no version that suits the Python version of Blender things become quickly complicated.
In particular, it there is no wheel available that forces me to create one and to provide it with the add-on. Deployment and maintainance ar then more tricky.

@JeanChristopheMorinPerso, @reinecke ~ do you have any notes to share in this thread on what's necessary for automation around Python 3.10 OTIO wheels?

[JeanChristopheMorinPerso]

The best notes are going to be when I added Python 3.9 support I think, see https://github.com/PixarAnimationStudios/OpenTimelineIO/pull/1080/files for anyone interested in contributing.

As for Mac M1, that's a different story. I left some notes in #1214.

So all in all, adding 3.10 support should be a straight forward task for anyone interested in contributing. I'd like to do it but I have limited bandwidth right now.

[JeanChristopheMorinPerso]

And for the curious, I've been running OTIO with Python 3.10 for a while now (locally) and I haven't hit any issues, at least on Linux.

This is the error I get when installing opentimelineio under shotmanager addon with Blender 3.2 and 3.1 which is using python 3.10

Hello Gattung, thanks for the details. The cmake error indicates that the Python headers and libraries corresponding to the Python libraries in your copy of Blender are not being detected.

The one thing I recall from others' experiences in building OTIO with Blender is that if you can set up the build such that cmake can find corresponding headers and libraries, the build will succeed.

Unfortunately the Blender build environment is not one I am that familiar with. Perhaps someone has details on how to set this up, or better recollection than I on solving this issue.

If I remember, people have built OTIO separately into a standard Python environment corresponding to Blender's python version, then manually moved it into Blender's site-packages area.

Hi @Gattung,
I'm the developer of Shot Manager. Indeed at the moment the current wheel for OTIO is not compatible with the Python version in Blender 3.1 and 3.2 so its install is failing. And I recognize that this fail is not so well handled by the actual version of Shot Manager (V1.7.10).

I'm currently working on both topics and a new release of Shot Manager should be release next week.
On the OTIO side, thanks to the help of @JeanChristopheMorinPerso and a teammate, we forked and managed to generate the wheels for Windows plateform for Python 3.10. I'm currently testing them - as much as I can - and we should be able to submit a merge request very soon. Hopefully it will be integrated in OTIO and an official set of wheels will be placed on PyPi so that the installation of Shot Manager can work again.

So stay tuned ;)

@JeanChristopheMorinPerso Hi Jean-Christophe,
I'm currently testing the wheel I generated for Otio 0.15 for Python 3.10 in Blender 3.1. The creation of the wheel went well and so does the installation. But when I call the function to get the version I get an error. On 0.14 this works fine.
Is ther something wrong on my side or is this an issue in 0.15?

Thank you

On 0.14:

And on 0.15:

I see the same thing.

The __version__ variable is added by the setup.py script, here. So if it's missing, check if you have any errors when running a build.

Looks like that bit of setup.py is not running. __init__.py in the published location does not have the DUNDER bits in it.

[JeanChristopheMorinPerso]

#1238 is the culprit I think. build_py runs before build_ext.
