IndexError: index -1 is out of bounds for axis 0 with size 0

Every time I make a sound with the voice changer on I see these errors:

VC PROCESSING!!!! EXCEPTION!!! index -1 is out of bounds for axis 0 with size 0
Traceback (most recent call last):
  File "voice_changer\VoiceChanger.py", line 467, in on_request_sola

IndexError: index -1 is out of bounds for axis 0 with size 0

No sound is being generated due to this.

I think the microphone input must have failed. Try creating a wav file and entering it in the input. If it converts successfully, then the microphone input has failed.

I tried using a wav file, same thing happened. I also tried using multiple other vc versions and none of them worked.

I also got this error when loading the model:

It turns out there's something wrong with my model. I'm not sure why though as it does work in colab

[w-okada]

Is there any other errors in the log? Showing me the whole log might help me figure out the reason.

no res close

I get the same error when selecting a microphone as input. If I select None it seems to work with res(ms) getting a value. But when I select a microphone res(ms) remains zero (or whatever is was before) and I get a very similar error-message:

[Voice Changer] VC PROCESSING EXCEPTION!!! index -1 is out of bounds for axis 0 with size 0
Traceback (most recent call last):
  File "voice_changer\VoiceChanger.py", line 472, in on_request_sola
  File "voice_changer\RVC\RVC.py", line 374, in inference
  File "voice_changer\RVC\pipeline\Pipeline.py", line 164, in exec
IndexError: index -1 is out of bounds for axis 0 with size 0

Using a file as input results in the same error. When pausing the file playback the errors stop, and res(ms) seems to be getting a value too, but when starting playback it is the same as with the microphone. For some reason, after clicking some button and changing values, and after a pop up came up saying "エラーが频発しています。対象としているフレームワークのモデルがロードされているか确认してください。", the error did vanish and res(ms) was getting values, but it did not output any sound. The recording button returned a silent wav file. I tried to recreate this behavior by restarting the program but I couldn't.

I'm just now getting this error out of nowhere. Literally changed nothing but switched models back and fourth, now can't use a model I used originally without this error. ???

edit: This error seems to only show up on one specific model I used previously, when turning index from 0 to 1. Any value above 0 yields same error.
