@rarts Never heard of it before. I did a quick test adding dependencies to my project and fired up jupyterlab and everything worked without hassle. Thanks for your recommendation, I will probably use it for now.

I mainly use GNU Guix but I have to use some packages that are still unpackageable there.

And then I tried #pdm. The packages are downloaded and the environment is set up, but when I launch Jupyter Notebook/Lab it tries to write jupyter files to /usr (??).

I spent the last hour trying to reproduce a Python environment to run my own code, for which I generated a environment.yml from conda a while ago. But conda gets lost trying to import it.

Guess I'll have to try Poetry again, until I find a dependency or package manager that works among the many others there are.
