Jupyter Notebook launch fail from terminal

Question

I am getting the following error message on launching Jupyter Notebook. I did conda update all already, but to no avail.

Traceback (most recent call last):

Would probably need a little mote information on how you're trying to launch it, on what system and what program etc. But assuming you have conda installed and the environment activated via conda activate my_env_path_name , you should be able to launch jupyter notebooks by typing jupyter notebook
