Install with a package manager

First: a virtual environment

Python's own advice: install into a fresh environment, in its own folder (~/ffsubsync), so it can't clash with other tools.

mkdir "$HOME\ffsubsync" -Force | Out-Null
cd "$HOME\ffsubsync"
python -m venv .venv
.venv\Scripts\Activate.ps1

Smaller install: torchNeeds Python 3

Only the parts for torch.

pip install ffsubsync[torch]
