I installed Jupyter notebook and labs on and EC2 instance and for some reason I get the following error:
ImportError: cannot import name 'filefind' from 'traitlets.utils' (/usr/lib/python3/dist-packages/traitlets/utils/init.py)
Jupyter opens fine in the browser but I can't seem to be able to work in an python notebook.
I disencourage the solution of op. Downloading and overwriting python libraries is not the way of keeping your system stable and clean!
What I found out is that while installing Jupyter notebook it had found four significant errors which resulted from python3 packages that were not installed correctly within that installation itself.
ERROR: ipykernel 6.6.0 has requirement traitlets<6.0,>=5.1.0, but you'll have traitlets 4.3.3 which is incompatible. ERROR: jupyterlab-pygments 0.1.2 has requirement pygments<3,>=2.4.1, but you'll have pygments 2.3.1 which is incompatible. ERROR: nbconvert 6.3.0 has requirement pygments>=2.4.1, but you'll have pygments 2.3.1 which is incompatible. ERROR: nbconvert 6.3.0 has requirement traitlets>=5.0, but you'll have traitlets 4.3.3 which is incompatible.
The solution is to just patch the packages to the newest version with:
pip3 install traitlets==5.1.1
pip3 install pygments==2.4.1
This applies to all similar cases where outdated packages prevent you from your installation
Oke fixed it! It seems like the problem was that the "traitlets/utils/init.py" was empty. So I copy-pasted the code from GitHub and that worked.
https://github.com/ipython/traitlets/blob/main/traitlets/utils/__init__.py
I got this problem twice when I installed two different ec2 instances installing cuda and cudnn. So it might that this has something to do with the origins of this issue.
The proper way to fix this problem is by upgrading/downgrading the library. Check the other answers to this post for guidance.
I faced the same issue. Downgrading the versions of traitlets and pygments alone, as suggested by @luarzou, didn't solved the problem for me. I also downgrade ipykernel and it works now:
pip install ipykernel==6.0
I opened an issue: https://github.com/ipython/ipykernel/issues/857
Edit: actually this error can happen when your venv has versions of ipykernel or its dependencies different than the env running jupyter. I suggest in that case to delete and recreate your venv, and verify that you don't install there packages that will break the communication/compatibility.
