How do I troubleshoot Jupyter kernel issues?

I'm having trouble with my Jupyter notebook kernel. It keeps crashing. What should I do?

First, try restarting the kernel. You can do this from the menu: Kernel > Restart. If that doesn't work, check for any error messages.

I restarted it, but it still crashes. What else can I check?

Make sure your packages are up to date. You can update them using pip or conda. Also, check if your notebook is using too much memory.

How can I check the memory usage?

You can use the command !free -m in a code cell to see memory usage. Alternatively, check your system's task manager.

Thanks! What if I still can't resolve the issue?

If the problem persists, consider reinstalling Jupyter or creating a new virtual environment to isolate the issue.
