Hello everyone,
Today i tried to install the Jupyter Notebook application to start my data science journey.
I could not connect to Kernel when I launched the the notebook from my CMD line.
The notebook itself launched fine but it was impossible to execute any code since it couldn’t connect.
When I launched the Jupyter notebook online the kernel connects automatically without hesitation.
I have looked at documentation and all the threads on Jupyter that I could find but nothing solved my solution of connecting with the kernel. I tried downgrading tornado, re-installing everything but it did not work. I installed everything via pip installs. I first reinstalled all the different modules to make sure the error was not there. Below is the command message i get when running JN.
I would be very grateful if someone could tell me what i am doing wrong since this is my last resort.
Kind regards
