NVDA 2024.1/Python 3.11 compatibility

[josephsl]

Hi Carter,

I'm sure you might be thinking about this, but just in case we want to keep it here:

AI Content Describer is incompatible with NVDA 2024.1/Python 3.11 as Pillow 9.3.0 pyd files are for Python 3.7. Thankfully, Pillow 9.3.0 is available for Python 3.11, so it is a matter of bringing py311 pyd files to the ad-on repo.

Thanks.

Am I correct in assuming that we can simply copy the PYD files:

• _imaging.cp311-win32.pyd
• _imagingcms.cp311-win32.pyd
• _imagingft.cp311-win32.pyd
• _imagingmath.cp311-win32.pyd
• _imagingmorph.cp311-win32.pyd
• _imagingtk.cp311-win32.pyd

to the PIL folder to make it compatable with NVDA 2024.1 and keep support for older versions? Asking as I'm currently working on a travel computer and don't have the infrastructure to run from source. If so, I'm happy to add those and update the manifest accordingly.

Hi, yes – given that .py files do not change across Python releases, we can simply drop in py311 pyd files. Once you update the manifest, I advise using a dedicated dev channel to post 2024.1 compatible test version as NVDA API is not frozen yet. Thanks, and keep up the good work.

Hi, one more thing: be sure to test the add-on with 2024.1 alpha to make sure regressions due to wxPython 4.2.1 are not found. Thanks.

Hello. I'm running NVDA 2024.1 RC 1, AI Content Describer Main commit 39374a5, latest of the posting of this comment, and at NVDA startup I'm getting this error

IMPORTANT: PLEASE READ THIS FOR ADVICE ON HOW TO SOLVE THIS ISSUE!

Importing the numpy C-extensions failed. This error can happen for
many reasons, often due to issues with your setup or how NumPy was
installed.

We have compiled some common reasons and troubleshooting tips at:

    https://numpy.org/devdocs/user/troubleshooting-importerror.html

Please note and check the following:

  * The Python version is: Python3.11 from "C:\Program Files (x86)\NVDA\nvda.exe"
  * The NumPy version is: "1.21.6"

and make sure that they are the versions you expect.
Please carefully study the documentation linked above for further help.

Original error was: No module named 'numpy.core._multiarray_umath'
"

It used to work before CV2, even on the beta. I think the error is being caused by the included Numpy for 3.11. Describing navigator object etc works without issue however.

I think we may need to distribute separate versions of the dependencies based on the version of python in use. Otherwise the addon package will become unnecessarily large (thanks a lot to CV2 and NumPy).

Version 2024.04.14 fixes this issue with the dependency downloader. Any issues with the feature can be opened in separate tickets. Closing as complete.
