Jupyter notebook cannot be saved. Cell execution freezes.

[sataset]

Bug: Notebook Editor, Interactive Window, Editor cells

Happened randomly twice. Same notebook, no major changes both in code and extensions. Lost hours of my work because of this.

Steps to cause the bug to occur

Unknown.

Actual behavior

Notebook cannot be saved (neither with cmd + s nor after closing. it will prompt if I want to save it but it does not work). Cell execution freezes, but other cells could be executed.

Expected behavior

Notebook saved. Cell runs normally.

Thanks for the bug.

The error in your console log should be an intellisense issue and shouldn't affect saving.

The execution getting stuck is also unrelated to the save problem. That would be a pytorch issue (and you'd have to restart the kernel as you've done instead of interrupting it).

However the save problem is rather bad. If you repro again can you include your entire console log? (Help | Toggle Developer Tools, click on the console tab, right click, save as an upload). Thanks.

[sataset]

@rchiodo Thank you for response.

It should not be pytorch issue because previously I have been making simple notebook with only two libs (numpy os) and lost my work with exactly same two issues.

I will save a complete log as soon as I will experience this problem again.

[rchiodo]

Are you saying you lose work whenever the execution hangs? That would likely be this bug here:
https://github.com/microsoft/vscode-python/issues/12514

[sataset]

I cannot be sure if that exact problem causes it but it seems like this. Thank you for reference. I will try to test it with autoSave feature enabled too.

[sataset]

Providing full log after cell freeze.

Confirming that the save issue is not related to this problem (at least on the last version of extension).
