docker run --gpus all -it -v ${PWD}\training:/tmp/xtts_ft/run/training athomasson2/fine_tune_xtts:latest

Is how the docker image is used on windows

That'll make it so that the training docker image folder points to your local folder on your computer named "training", then all the models generated in the program will be saved in that training folder on your computer.

this zip folder should be unzipped into that local folder you havae named training, cause it holds the original needed models and such
