None of the notebooks work in Jupyter Lab - Kernel never connects

[hgoumner]

Hello,

First I'd like to thank you for making this tutorial. Unfortunately when I try to run any of the notebooks I have a problem. The Julia (1.9.2) kernel never connects.

In the terminal I see a lot of this:

[W 2023-07-19 18:42:15.727 ServerApp] Nudge: attempt 120 on kernel df4c7181-386c-4058-b736-cbca730a176a

followed by:

[E 2023-07-19 18:42:16.046 ServerApp] Uncaught exception GET /api/kernels/df4c7181-386c-4058-b736-cbca730a176a/channels?session_id=04195f4b-a49b-4423-abb3-690ce7f17c80 (::1) HTTPServerRequest(protocol='http', host='localhost:8888', method='GET', uri='/api/kernels/df4c7181-386c-4058-b736-cbca730a176a/channels?session_id=04195f4b-a49b-4423-abb3-690ce7f17c80', version='HTTP/1.1', remote_ip='::1') Traceback (most recent call last): File "/home/hristo/miniconda3/envs/wbs_bootcamp/lib/python3.11/site-packages/tornado/websocket.py", line 944, in _accept_connection await open_result TimeoutError: Timeout

The notebooks from the introductory Julia course work without any issues. I have also installed all dependencies because when I run the code from the notebooks in a Julia REPL, I do not get any errors.

Does anyone have any ideas how to get the notebooks to work?

Thanks in advance.

I removed the toml files like another person suggested and it works now.
