Hi, The SpleeterGui encountered an error while working and could not separate the music. The infomation:

Run complete

Note: There is no this path D:\obj\windows-release\37amd64_Release\msi_python\zip_amd64\runpy.py on my disk.

Thanks for including the full error.

That weird D:\ path is baked in to the code, not the problem.

The source folder looks ok, what's your save path?

[nottellyou]

I select the save_path F:\temp_files\au\tmp.

The answer seems to be here: https://github.com/boy1dr/SpleeterGui/issues/188

[boy1dr]

That was my next guess. Your save path looks fine.

Python will do a download of the model files the first time you each stem mode, something must be blocking it.

You can try running SpleeterGUI with administrative privileges, or use the older larger installer. Let me know if you can't find that link.

Thinks @boy1dr

I have the same issue even I run with admin privileges, it seems it didn`t download the models... So I just download these models(https://github.com/deezer/spleeter/releases) into \SpleeterGUI\pretrained_models manually...
