$PYTHONPATH for jupyter notebook (and jupyter notebook within jupyter lab)

[Eric Gayer]

Hi guys, 

I am struggling to understand how to permanently set the path to my own modules directory for any jupyter notebook (and/or any jupyter notebook in jupyter lab).

In spyder, the PYTHONPATH manager helps adding paths pointing  modules.

Using jupyter notebook, all I found is to add this piece of code each time we start/create a notebook

import sys
sys.path.append("path to my modules dir")
import mymodule as mm

How to permanently add a path to modules so every new jupyter notebook understand it ?

Thanks for your help

Eric

You could include this in a startup script.

But I don't think you should do this. It'd be more transparent and transferable (e.g., if you had to email a notebook to a colleague) to create a setup.py file for your module and install it as a proper library.

You can add environment variables to the kernelspecs.

thank you guys for your answers, however with my rather low "technical skills" I am still doubtful on the easiness of how to do it properly...

would it be possible to point me to a documentation that explains kernelspecs ?

thanks
