> The article shows some advantages compared to plain virtual environments
No; they are plain virtual environments. There is no special kind of virtual environment. Uv simply offers its own command structure for managing those environments. In particular, `uv run` just ensures a venv in a specific location, then uses it.
There is no requirement to activate virtual environments in order to use them (unless you have some other tooling that specifically depends on the environment variables being set). You can, similarly, "just do"
.venv/bin/python myscript.py
> This command automatically picks up the correct virtual environment for you
Some people dislike such magic, especially since it involves uv having an opinion about where the virtual environment is located.
Sorry, you're right I should have said "plain venv", as in the program.
`uv run` will also sync the environment to be sure it exists and meets the correct specifications.
But yes, it's optional. You can also just do `uv sync` to sync the environment and then activate it like normal.
Or use `uv venv`, `uv pip` commands and just take the speed advantage.
