What happened?

Hi bros,

I got a issue, steps to reproduce as below:

• Install jupyterlab as tutorial https://research.google.com/colaboratory/local-runtimes.html#:~:text=In Colaboratory%2C click the "Connect,connected to your local runtime.
• Copy uri after starting jupyter server (http://localhost:8888/?token=a96d38b9077b2c7cfd05d4e255286febcb4bbaf0c5f86f27)
• Install Jupyter extension on vscode
• Connect colab runtime to local jupyter server:
  • Click connect https://gyazo.com/dcd8e4636361213a24dc56e1481efacf
  • Paste uri link that copied https://gyazo.com/53c9edd93f92abbb48fcc39847f21016
• Connect vscode to local jupyter server:
  • Open vscode -> Ctrl + Shift + P -> Jupyter: Specify Jupyter Server for Connections -> Existing -> paste uri link that copied
  • URL (http://localhost:8888/?token=a96d38b9077b2c7cfd05d4e255286febcb4bbaf0c5f86f27)

Result: Colab connect runtime to local jupyter server successfully. Vscode can’t connect local jupyter server.

Thanks in advanced for your help!

Running Jupyter locally or remotely?

Local

[rchiodo]

#10435 should address this problem.

The general problem of ‘local’ vs ‘remote’ not being clear is something on our radar though. Some ideas are here: https://github.com/microsoft/vscode-jupyter/issues/10363 https://github.com/microsoft/vscode-jupyter/issues/10435
