What's the error?

When I duplicate it, I found the following error.

This error is empirically common with RVC. It means that omegaconf is not compatible with the latest pip. Add in requirements.txt with git+https://huggingface.co/datasets/soiz1/omegaconf.

Please let me know if it works.

It worked for me, but if it doesn't work please let me know.
My space(https://huggingface.co/spaces/soiz1/RVC_V2_Huggingface_Version) is working.

IT WORKED!!! Thanks a lot, how about you make a public space to update it!? Please? (I don't wanna take credit for your work.)

How'd you even figure that out!? I mean, how did you know to use that link??:

git+https://huggingface.co/datasets/soiz1/omegaconf

I just edited requirements/base.txt in omegaconf.

PyYAML>=5.1.* ⇢ PyYAML>=5.1.0

I'd be happy if you followed me... Just kidding!

I did follow ya! But... Uh, that's a dataset, haha... not a space... 😅

(brilliant change though, I would've never figured that out.)

I hope this helps someone. Also, this error occurs in most RVC spaces, so if anyone is having the same problem, please give them the URL to this discussion.

Ilaria RVC has applied it, so it's now easy to duplicate.
