Environment data

• VS Code version: 1.35.0-insider (snap)
• Extension version (available under the Extensions sidebar): 2019.4.12954
• OS and version: Arch Linux
• Python version (& distribution if applicable, e.g. Anaconda): Anaconda
• Type of virtual environment used (N/A | venv | virtualenv | conda | …): conda
• Relevant/affected Python packages and their versions: jupyter 1.0.0

Expected behaviour

Interactive Python should work as described in Readme.md of vscode-dev-container example of Python 3 Anaconda. https://github.com/microsoft/vscode-dev-containers/tree/master/containers/python-3-anaconda

Actual behaviour

Debugging in container works but the Interactive Python does not. VSCode keeps trying to start the jupyter-server.

BTW, when I change the blocking line to

const knownDark = true;

and let it continue, Python extension do connect to Jupyter server and it seems to get cell executed. However, no output is still displayed in “Python Interactive” tab.

If you go to ‘Help | Toggle Developer Tools’, open the console, right click and save as, I can help diagnose the problem.
