Could you try pip install torch==2.1.1 in that same virtual env and see what you get?

I should lock down the versions of all the dependencies, I'd like to do that with pipenv but I haven't had time to get to that. Wondering if there's a newer release of torch that is causing some dependency problems... If the torch installed pinned to 2.1.1 works but you hit other issues, at least it can help point us in the right direction.

Same error still persists after trying to install 2.1.1

Could you try editing requirements.txt and removing the "deepspeed" line? I tried on windows 11 and that was what was causing the problem. I am not sure why deepspeed won't install, maybe someone else who is running this on windows can chime in on that. But without deepspeed, the install went great for me, let me know if it works for you.

EDIT - actually pip install . worked great but epub2tts doesn't run (I get a "ImportError: cannot import name 'etree' from 'lxml'" error). I'll poke at it a little bit to see if I can figure out what's going on. If you are able to run wsl and install it under that though, it will probably work out better for you.

[aedocw]

Closing due to lack of response. If other people are hitting the same error on windows please mention it here and I'll re-open, and try running on windows.

pip install . --no-build-isolation works for me @aedocw

Edit - well...it fixed that error anyway
