Describe the issue

why am i getting this:

Hi @krembuk , I cannot reproduce, I tried conda env (with python3.12) and python venv (with python3.10), both work at my side.

Could you download and run collect_env.py, and attach the result here, as well as the result of pip list

Thanks!

[hwbox]

I'm encountering the exact same issue with the identical error message. After running the collect_env.py, the output is as follows. I'd greatly appreciate any helpful suggestions or insights. Thank you!
