Jupyter notebook doesn't start and returns errors: KeyError: 'cookie_secret' and TypeError: Missing required parameter 'digestmod'.

[gekaklam]

Hi,

I've just cloned this repo on a new anaconda installation, Ubuntu 20.04. I followed the instructions and after the "make pip-tools" finished, I tried to run "jupyter notebook". I'm getting the following error.

I've spent quite some time trying to troubleshoot this with no success. Can someone confirm if they're having the same issues or if it's just me?

(fsdl-text-recognizer-2022) gekaklam@eru:~/projects/fsdl-text-recognizer-2022$ jupyter notebook
Traceback (most recent call last):
  File "/home/gekaklam/anaconda3/envs/fsdl-text-recognizer-2022/lib/python3.8/site-packages/traitlets/traitlets.py", line 537, in get
    value = obj._trait_values[self.name]
KeyError: 'cookie_secret'

During handling of the above exception, another exception occurred:

I'm pretty stuck on this too. Did you manage to fix this?
