This corresponds to the lightweight branch of rvc_tts_pipeline. Despite its name, it includes all of the pth files needed to run rvc so it's a decently large file.
I have uploaded it on HuggingFace due to git size limitations and can be downloaded directly here: https://huggingface.co/Jmica/rvc/resolve/main/rvc.7z
Or you can download the lightweight one that DOES NOT include the pretrained models: https://huggingface.co/Jmica/rvc/resolve/main/rvc_lightweight.7z
Or you can check the files on the HuggingFace Repo: https://huggingface.co/Jmica/rvc/tree/main
