VScode cannot read or use the 'PYTHONPATH' variable in the 'env' in kernel.json

[lester1027]

Environment data

• VS Code version: 1.77.3
• Jupyter Extension version (available under the Extensions sidebar): v2023.3.1201040234
• Python Extension version (available under the Extensions sidebar): v2023.6.1
• OS (Windows | Mac | Linux distro) and version: Windows 11 WSL 2
• Python and/or Anaconda version: Python 3.10.5, Anaconda 4.12.0
• Type of virtual environment used (N/A | venv | virtualenv | conda | ...): conda
• Jupyter server running: Local | Remote |: local

Expected behaviour

I added a kernel.json file under ~/.local/share/jupyter/kernels.

{ "argv": [ "/home/lester/anaconda3/envs/mne/bin/python", "-m", "ipykernel", "-f", "{connection_file}" ], "display_name": "Python 3 - MNE", "language": "python3", "env": { "PYTHONPATH": "/mnt/c/Users/leste/OneDrive/Frutta/MindAmp/git/eeg_device" } } The Jupyter kernel should be able the append the path(s) in the PYTHONPATH automatically.

Actual behaviour

Only the browser jupyter can do that. Vscode notebook fails in doing so. sys.path does not show the PYTHONPATH added

Thanks for filing this issue, I will have a look at this. For now, you can create a .env file in your workspace folder and add PYTHONPATH=... into that and the kernel will use that.

@lester1027 I have tested this and it works as expected. Please let me know if this problem still persists.

I'm seeing the same issue as raised by @lester1027, specifically when starting a kernel through a remote tunnel.
