Original GitHub issue: https://github.com/RVC-Project/Retrieval-based-Voice-Conversion-WebUI/issues/2737

I'm using Linux Mint 22. I'm using a venv in Python 3.10. I tried the installation instructions and it has all gone well except for trying to launch using python infer-web.py, where I'm getting:

(venv) PC:~/Retrieval-based-Voice-Conversion-WebUI$ python infer-web.py

ImportError: cannot import name 'media_data' from 'gradio_client' (/home/username/Retrieval-based-Voice-Conversion-WebUI/venv/lib/python3.10/site-packages/gradio_client/init.py)

Some people in other threads have said something about the possibility of not having right versions of dependencies, but I had no trouble with the pip installs. I don't know how to check the version of my dependencies. I know very little about coding and I'm just trying to get RVC to work on my Linux computer like it did on Windows. I literally only created this account because I couldn't find anything else about this error. Any help please?

UPDATE: I figured out "Gradio" is a program that RVC presumably needs, so I entered the venv and ran pip install --upgrade gradio as per the installation/update instructions on the gradio github page. Now when I run 'python infer-web.py' it progresses further, but I've hit another problem:

I can't find where exactly it's finding this keyword argument. So I don't know how to fix it. Help?

The requirements.txt of this project doesn‘t specify the version of gradio_client. I solved this problem by specifying the version of gradio_client as 0.2.10.

I solved the gradio issue by updating it, it's now version 3.34.0. But I'm still getting the Blocks.queue issue.

Thank you, this worked! Finally got the UI to open! I had another error upon trying to convert a file, but it was fixed by reinstalling Torch as version 2.5.1: https://github.com/RVC-Project/Retrieval-based-Voice-Conversion-WebUI/issues/2419

Thanks so much!!
