[yuxumin]

same here, have you figured out what's wrong with that?

[Volkopat]

Downgrading gradio version helped me, I don't have access to my laptop at the moment but somewhere in the issues section you may find the exact version

[yuxumin]

This is so strange, I don't even have Gradio in the environment where I run the marker.

Oh my bad the gradio part is what I was working on. As far as I remember, this was a problem with one of the packages in poetry. Take a look at my pyproject.toml:
