pywintypes.error: (50, 'GetFileSecurity', 'The request is not supported.') while using Jupyter Notebook on network drive

问题

I am currently trying to use a combination of miniconda + jupyter (installed with pip) on a network drive and I get the following error:

pywintypes.error: (50, 'GetFileSecurity', 'The request is not supported.')

I am currently working in a corporate set-up, so we are working with some limitations regarding access rights. Unfortunately, I can only try jupyter on network drives, changes to the local hard drive requires admin rights which I don't have.

The full error output:

ywintypes.error: (50, 'GetFileSecurity', 'The request is not supported.')

Any ideas or experience with this type of error?

回答1:

For anybody having this issue, it seems to be due to updating jupyter notebook, or any other package that can update it.

The steps to fix the issue are the following,

pip install jupyter pip install jupyter-client==5.3.1 python -m ipykernel install --user
