Error: Timed out waiting to get a heartbeat from kernel process

Issue Type: Bug

Steps taken:

• Created a virtual environment using venv
• Installed a number of packages
• Tried to run my first cell - importing a number of packages
• Received the error: ‘Timed out waiting to get a heartbeat from kernel process. View Jupyter log for further details.’

My log can be found below.

This is an issue that seems to happen intermittently. I previously raised it as #7863, but closed the issue as I thought it was fixed when I moved to VSCode 1.61.0. But I’m experiencing it again.

Following @DonJayamanne’s advice, I’ve tried installing the insiders build and have received the same error there.

[DonJayamanne]

Thanks for the feedback.

I believe the issue is because of the firewall. We spawn a process that’s on a network drive and 5 sockets are opened against that process. I’d consider moving this into a local drive or tweeking the firewall accordingly.

I’m going to close this issue as this is an environmental issue and things work as expected Regen thinking on a local drive.

@DonJayamanne it looks like we might be hitting the ipython_genutils issue with Venvs too 😦
