gather_sources_and_dependencies fails in notebooks with ipykernel 6.21.0 #909
Description
Jupyter released 6.21.0 on the 31st of Jan.
It includes ipython/ipykernel#1078 which adds a file variable. Sadly, that file doesn't actually exist....
Reproduce in a notebook with
pip install ipykernel==6.21.0
from sacred.dependencies import gather_sources_and_dependencies
gather_sources_and_dependencies(globals(), save_git_info=True)
