Fatal Error when starting jupyter notebook

For Windows users that have anaconda installed, try on Windows CMD/Powershell (better if you run it as admin):

(Assuming your environment is named "root")

activate root
jupyter notebook

Hope that helps

I believe you need to open Jupyter notebooks by typing jupyter notebook in the anaconda prompt, not the regular windows command prompt.

In my case, There was one redundant path of python3 added in the environment variable already and I was adding again. I just removed that path and run jupyter notebook through command prompt and it worked perfectly.
