Hi. I tried running jupyter notebook recently and faced with the following issue. I run local jupyter server, try to open any notebook from filesystem and I get 500 : Internal Server Error.
Here are logs from jupyter server.
[E 22:47:46.040 NotebookApp] Uncaught exception GET /notebooks/sem_tasks/05_data_files2/TOBD_sem_05_data_files2_v2_blank.ipynb (127.0.0.1)

I installed jupyter with the following steps.
sudo pip3 install virtualenv
virtualenv env
source ./env/bin/activate
pip3 install jupyter
When faced issue for first time tried to google it. Found a recommendation to update pygments to >=2.4.1. Did pip3 install --upgrade pygments. Didn't help. Also tried to update nbconvert. Didn't help as well.
Here is the list of packages in pip3:
