Your system

First: a virtual environment

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

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

pipNeeds Python >=3.10,<4.0

pip install ui-tars
