Jupyter in vscode run very slow in Macbook air m1

[wybert]

Environment data

• VS Code version: 1.72.0 64bbfbf67ada9953918d72e1df2f4d8e537d340e arm64
• Jupyter Extension version : v2022.9.1002791758
• Python Extension version (available under the Extensions sidebar): v2022.16.0
• OS (Windows | Mac | Linux distro) and version: macOS 12.6 21G115 arm64
• Python and/or Anaconda version: conda 4.12.0
• Type of virtual environment used (N/A | venv | virtualenv | conda | ...): conda
• Jupyter server running: Local

Expected behaviour

Run quickly in seconds

Actual behaviour

Run very slow

Steps to reproduce:

I don't know how to reproduce, it is not always slow but sometimes very slow. When I switch back to Jupyter-lab, it will be very fast. In windows, it never happens:)

I know there are some same open issues like 7069, but they are all closed. Also, when I use Vscode Jupyter by remote ssh (with some Linux servers) through vs code. This also never happened.

Is it running a cell that takes a long time or opening/editing the notebook?
Does it occur often enough that you could capture logs for us? If you can, set the Jupyter: Logging Level to verbose and copy the content of the output window: Jupyter: Show Output when this happens again.

It's running a cell that takes a long time. I will continue to track this problem and get feedback here.

I just caught this bug again.

• Are you connecting to a remote jupyter kernel? I think you are
• Is your workflow as follows:
  • Open a notebook,
  • Select a remote kernel
  • Run cell
  • And you notice a delay.
    If this is the case, then the delay is expected for the first time as we need to first connect to the remote kernel.
    Jupyter is fast as the application is already launched, where as in VS Code, we first need to connect to the jupyter server and then connect to the remote kernel.

Please could you enable logging as follows:

• Open settings & go into Jupyter->Logging
• Change the value to verbose
• Reload VS Code,
• Attempt to repro the issue & then copy the output from the Jupyter output panel.

[wybert]

Actually, my workflow is as follows,

1. open my work path with code
2. open the Jupyter notebook from VS code's sidebar/the explore
3. change the kernel to another kernel
4. work on the notebook and all is good until the bug happens.

I already changed the setting to verbose

and the above is the output from Jupyter output panel. Have I missed something?

[DonJayamanne]

Please could you upload all of the logs, you don't seem to have uploaded everything.

change the kernel to another kernel

Also, are you connecting to a remote kernel or local kernel?

[wybert]

Local kernel.
When I try to investigate a data frame, It takes seconds.

The whole output is too long to put paste here. I put it in a text file below.
Visual Studio Code -Jupyter- Output.txt

Feedback about this issue. After disabling all my extensions except the python extension, it seems that the problem has gone. I want to keep this issue open for a while (maybe one more month) to see if I still got the same problem. I will get my feedback then.

[DonJayamanne]

Its been over 3 weeks, lets close this for now.
@wybert If you run into this again, please feel free to ping here and I'll reopen this issue or please feel free to create a new issue and I'll look into thath

[wybert]

After I disabled all the extensions except the Python extension, it seemed to work well. Cheers!
