[alcoftTAO]

I have this error when using vc.get_vc("/home/alcoft/Descargas/Modelos RVC/I4.0 V4/NEKOTSUBA_BI_VOICEVOX.pth").

This is the traceback:

My Python version is Python 3.11.6 and the model path is /home/alcoft/Descargas/Modelos RVC/I4.0 V4/NEKOTSUBA_BI_VOICEVOX.pth.

Can someone help me fix this?

You need a .env file, which you can create with rvc env create. Then you need to fill out the paths listed in the .env file, and load the env file with load_dotenv(). You can get the files you need from below (I recommend checking the web-ui repository for more info on setup ), your error is saying you don't have a path to the index file.

Preparation of other Pre-models

RVC requires other pre-models to infer and train.

#Download all needed models from https://huggingface.co/lj1995/VoiceConversionWebUI/tree/main/
python tools/download_models.py

Or just download them by yourself from our Huggingface space.

Here's a list of Pre-models and other files that RVC needs:

./assets/hubert/hubert_base.pt

./assets/pretrained 

./assets/uvr5_weights

Additional downloads are required if you want to test the v2 version of the model.

./assets/pretrained_v2

If you want to test the v2 version model (the v2 version model has changed the input from the 256 dimensional feature of 9-layer Hubert+final_proj to the 768 dimensional feature of 12-layer Hubert, and has added 3 period discriminators), you will need to download additional features

./assets/pretrained_v2
