Set PYTHONPATH for local Jupyter Notebook in VS Code

Question

I'm using Visual Studio 1.39.2 on Windows 10. I'm very happy that you can run Jupyter Notebook natively through VS Code as of October this year (2019), but one thing I don't get right is how to set my PYTHONPATH prior to booting up a local Jupyter server.

What I want is to be able to import a certain module which is located in another folder (because the module is compiled from C++ code). When I run a normal Python debugging session, I found out that I can set environment variables of the integrated terminal, via the setting terminal.integrated.env.linux. Thus, I set my PYTHNPATH through this option when debugging as normal. But when running a Jupyter Notebook, the local Jupyter server doesn't seem to run in the integrated terminal (at least not from what I can see), so it doesn't have the PYTHONPATH set.

My question is then, how can I automatically have the PYTHONPATH set for my local Jupyter Notebook servers in VS Code?

Answer 1

I'm a developer on this extension. If you have a specific path for module resolution we provide a setting for the Jupyter features called:

Python->Data Science: Run Startup Commands

That setting will run a series of python instructions in any Jupyter session context when starting up. In that setting you could just append that path that you need to sys.path directly and then it will run and add that path every time you start up a notebook or an Interactive Window session.
