Hi @neeti306

I'm not getting the picture. Within DeTT&CT we don't have nor use Jupyter notebooks. Can you share some more context on what you are trying to accomplish?

I'm trying to open jupyter notebook in anaconda and while doing that I'm getting the above error message (screenshot attached now).

[rubinatorz]

Which notebook? Because we don't have Jupyter notebooks on our DeTT&CT GitHub.

Did you manage to solve it? I'm having the same issue over here.

[neeti306]

No, I couldn't. However I have created new environment and installed most of the libraries/packages which are present in base package and its working fine.
