Jupyter Notebook Won't Execute: Stuck on [*]: Kernel buffering and restarting before timeout #431

Open rsq215 opened 5 years ago

rsq215 commented 5 years ago

I've read everything I can get my hands on in github and stackoverflow and cannot solve my problem. Running Windows 10 64bit, installed anaconda, and trying to run jupyter notebook. Launches fine, I can create a new Python3 file and it shows that I have a kernel. I try to run a simple command in the notebook and execute the cell and it just gets stuck on [*] and never executes. See screenshots below. I've updated conda, ipykernel, and jupyter notebook and all are current. I installed ipykernel with --user tag. I'm stuck on what else to try. I greatly appreciate any help available. Really need to get this to work for project I'm on. Thank you all.

My first guess, given that this is Windows, is that there is a firewall or av software filtering localhost traffic. Sometimes this can be fixed by using either:

jupyter notebook --ip=localhost

or 

jupyter notebook --ip=127.0.0.1

Often exactly one of those works and not the other, and it will depend on the environment which one is the happy one.
