I am working in an environment where writing to the disk space with a folder name like .ipynb_checkpoints
is disallowed.
Unfortunately, this is Jupyter Noteb
Not exactly an answer to your question, but perhaps close enough.
The path of the checkpoints folder is configurable so you could rename it to something allowed such as "_ipynb_checkpoints", or you could move it to a completely different folder.
You simply have to add
c.FileCheckpoints.checkpoint_dir = '_ipynb_checkpoints'
to jupyter_notebook_config.py
