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 -p ~/ffsubsync
cd ~/ffsubsync
python3 -m venv .venv
source .venv/bin/activate

Smaller install: torchNeeds Python 3

Only the parts for torch.

pip install ffsubsync[torch]
