The system crashes when running the “Hello NAS” example code with GPU

Author: miwimisawiCreated Feb 21, 2024Updated Jul 30, 2024

The crash occurs in three environments: colab, Windows11 system using conda, and Windows11 system without using conda.
In all three environments, I tried to downgrade pytorch to version 13.0, but it still crashes.
And it crashes when running in both .py and .ipynb modes.

My steps

colab: use pip to install nni and lightning, then run the “Hello NAS” example code.
Windows11: install pytorch (using the official installation instructions, which also installs torchvision), nni, lightning, ipykernel, jupyterlab

I cleared my environment beforehand, there are no extra package conflicts

The details of one of the errors

(Env: Windows11, using conda, pytorch2.2.0) Before the crash, I saw a lot of python.exe in the task manager I recorded the error at that time:
