Worked.

It fixed the issue i was getting using the text2image endpoint (There is no current event loop in thread 'AnyIO worker thread').

OS: Linux - Ubuntu 20.04 x64 Graphics card: RTX 3080ti

Thanks

I'm getting the same error on OSX - looking at the code, I'd imagine it doesn't fix it (since it's specific to win32)?

update: just tested the patch and it DOES fix the issue on OSX as well

Fixed for me as well

Ubuntu 20.04 with A100 80GB (suspect it's Python 3.8 that's the culprit)
