Restart Jupyter Kernel Without Losing Variables

A cool Jupyter hack.

While working in a Jupyter Notebook, you may want to restart the kernel due to several reasons. Instead of dumping the variables to disk before restarting Jupyter and reading them back, use the store magic command.

It allows you to store and retrieve a variable back even if you restart the kernel. This avoids the hassle of dumping the object to disk.

Would you like to have a free 1-on-1 call with me?

On Monday (15th May 2023), I will personally reach out to five readers with some of the best reviews and set up a free 1-on-1 meeting with them.

👉 What if you don’t make it to the top five reviewers?

No worries, I understand that you may have shared your experience because you really need my help.

Thus, I will still contact you over LinkedIn/Twitter/Email and provide personal support over chat.

In other words, you will definitely hear from me in any case, and that’s a promise.
