Can we use global marimo with a custom venv?

I'm really interested in that question as well!

yep! Quite magical things are happening with uv right now! These are 3 other useful ones:

uvx --with anywidget jupyter lab

uvx --with anywidget jupyter lab

uvx --with solara  jupyter lab

uvx --with solara  jupyter lab

uvx marimo edit hi.py --sandbox

uvx marimo edit hi.py --sandbox

Finally, I can also run marimo in a project with uv like this:

uv init (this will create a pyproject.toml file)
uv add marimo  (this will add "marimo>=0.9.9" to dependencies in pyproject.toml)
uv run marimo edit hi.py

uv init (this will create a pyproject.toml file)
uv add marimo  (this will add "marimo>=0.9.9" to dependencies in pyproject.toml)
uv run marimo edit hi.py

Awesome! Figuring out all this packaging stuff is like walking through fog, exploring and never knowing if you will reach the destiny. But on the path I think I figured out some best practices that I'll use now when working with marimo, that I'll share right here. 1. I'll have a global version of marimo installed via uv tool install marimo or with a specific python version using UV_PYTHON=python3.11 uv tool install marimo (this will overwrite the previous global installation) Furthermore, the global version of marimo can be updated via uv tool install marimo --upgrade. When I run a script with the global marimo version, I'll do that via marimo edit hi.py --sandbox When I run a script that already ran once with a --sandbox flag, I can simply omit this flag and run marimo edit hi.py The CLI tell me "This notebook has inlined package dependencies. Run in a sandboxed venv containing this notebook's dependencies? [Y/n]" and I'll press "Enter" to continue Now, when I don't want to use the global marimo, but a temporary marimo version instead, I'll run uvx marimo edit --sandbox hi.py this line is 100% identical to uv tool run marimo edit --sandbox hi.py because "uvx" is an alias to "uv tool run". I can also specify a python version here, like this uvx --python 3.13 marimo edit hi.py The thing about uvx marimo is the following: It's not installed, it's just cached. Runing uv cache clean will remove all artifacts from my system that were cached with uvx before. Another option is to work with a virtual environment using uv:

uv venv
uv pip install marimo
uv run marimo edit hi.py

uv venv
uv pip install marimo
uv run marimo edit hi.py

this venv can also be activated via source .venv/bin/activate and then marimo can be started via marimo edit hi.py . And always, if I'm not sure what marimo installation I'm currently using, I can run which marimo and it will show me the file path.

Awesome! But that I can also do with uvx --python 3.13 marimo edit hi.py , wich is maybe a bit cleaner. But is

uvx --python 3.13  marimo edit hi.py
and
UV_PYTHON=python3.13 uvx marimo edit hi.py

uvx --python 3.13  marimo edit hi.py
and
UV_PYTHON=python3.13 uvx marimo edit hi.py

100% identical?

I see! So in theory, the --python 3.11 flag could be called as well in that context?

just pasting the screenshot for documentation reasons, so that other members/LLMS can see the whole process.
