Creating a virtual environment

Windows:

py -3.10 -m venv venv
venv\Scripts\activate

Linux/MacOS:

python3.10 -m venv venv
source venv/bin/activate

Anaconda:

conda create -n so-vits-svc-fork python=3.10 pip
conda activate so-vits-svc-fork

Installing without creating a virtual environment may cause a PermissionError if Python is installed in Program Files, etc.

Hyperparameter Tuning

Most parameters have not been changed from those in VITS and seems to be "empirical" (or left alone).

Changing the train parameter basically will not cause the need to reset the model; changing LR, etc. may improve the training speed. The segment_size parameter is the length of the audio and the tensor to be passed to the decoder, and increasing it may increase the training speed of the decoder, but may not make much difference in terms of increased VRAM usage.

Changing the model parameter may reset some or all of the weights. The current model may be too large for one speaker or may not.

The ssl_dim is the number of input channels, and the correct number of output channels for the officially trained ContentVec model is 768, but after applying final_proj it is 256.

I lack understanding about this model and need to study more basics ....
