many thanks for your great work! after I pip install ., python opt.py, the error occurs, can you give me some help?

I have the same problem

[kravrolens]

cy

[muxizju]

Reason: the compiled package name and the folder name in the project are both "svox2", they will be mis-imported when using in the opt.py script. Solution: aftering "pip install .", just simply remove the folder"./svox2/svox2". Then everything will work
