Kernel dies after starting exploration strategy using NNI package

Question

I am following the nni package tutorial of Neural Architecture Search (NAS) https://nni.readthedocs.io/en/latest/tutorials/hello_nas.html.

But my kernel dies every time once I run

exp.run(port=8079)

The output is:

[2023-11-10 10:09:08] Creating experiment, Experiment ID: ...
[2023-11-10 10:09:08] Starting web server...
[2023-11-10 10:09:09] Setting up...

[2023-11-10 10:09:09] Checkpoint saved to .../checkpoint.
[2023-11-10 10:09:09] Experiment initialized successfully. Starting exploration strategy...

Then, the kernel died.

I am using Apple M1 Max if this is relevant. Any suggestions?
