Restarting kernel for one and only one .ipynb document in jupyter

Question

I have a process running in one of .ipynb document in jupyter for many hours using Python3 kernel. I don't need it to die. I was working in the other document in parallel using the same Python3 kernel and the process got stuck.

I wonder if I can restart kernel for one document only? Or at least to stop the process for this document. Interrupt the kernel button doesn't work.

Answer 1

Jupyter typically starts a new kernel for each notebook you open. So even if you have two Python 3 notebooks running, the kernels are not the same.
