preprocess.log won't inform you of anything useful, since this is a problem that occurs when training is about to start.

What solved it for me was running the bat from the location of the original directory used when installing everything.
So if you initially set things up in C:/SomeFolder, it will then give the FileNotFoundError if you've moved (and run the bat from) the repository outside of that directory, say C:/NewFolder/SomeFolder. In my case, I just had to move it back to C:/SomeFolder. During the process, it was looking for the required file in the new directory, but had saved it in the old directory.

Not sure how to reconfigure it properly, but that was how I solved it in my case.

With project, are you referring to where the original audio files are located, or where the unfinished training data is located? Apologies if my question is potentially stupid

At first, I tried creating a new folder within the project, placing the materials in this folder, and specifying the material path as the path of the newly created folder, but it didn't work. However, when I moved the entire 'rvc' folder with the materials to the root directory of the C drive, the program started running. I guess my initial path was too long for the program.

I cannot say for certain as to how and why, but this actually worked. Huh.

I guess it might be caused by spaces in the folder names.

It actually does seem like that this RVC web UI hates spaces. Everything works for me now since I've removed any and all spaces from my paths, and this specific error only appears when I've specified a path that contains spaces.
That is very annoying, but at least now I know how to avert the error.

I was able to resolve this issue by moving the training set data folder to the root directory where the UI .bat file is launched. If no wav file exists that means process data was unsuccesful, and looking at CMD error logs I saw FileNotFound error which was only resolved after moving the training data to the same directory as the WEB UI tool.

@qinglangee commented on GitHub (May 5, 2025):

The reason of the issue for me is the input folder name, 
in windows system, if we copy path with the end slash '\', 
this will break the infer\modules\train\preprocess.py  script,  
so there is no 1_16k_wavs  and  0_gt_wavs folders created.

用资源管理器复制路径就不会踩这个坑了。。。
