PTH to ONNX problem on RVC V2 Google Colab (solved)

[chilly ore]

Whenever i try to do ckpt to ONNX, it always has an error. I think its because there is something missing. This is what it shows on Colab: Traceback (most recent call last):

Quick thing to try: Make a code line in colab and run the command "pip install onnx"

You might have to close the web interface to do that

If that doesn't work, w-okada's voice-changer has a feature to export .pth models to .onnx

thats what i thought too

lemme try that

i still have a error about the directory : Traceback (most recent call last):

It looks like maybe it's getting a folder as an input when it's expecting a file. Is there a section in the web-interface where you have to write the name of the .pth file or maybe an output line where you have to maybe write the intended filename? Like /content/MyModel.onnx or something

[chilly ore]

that worked

thx

Sure thing!
