The following paths are the current contents of the load path. The
following entries are looked up for Python packages. Note that not
all items in this path are folders. Gray and underlined items are
entries pointing to invalid resources or used by custom import hooks
such as the zip importer.

Items with a bright background were expanded for display from a relative
path. If you encounter such paths in the output you might want to check
your setup as relative paths are usually problematic in multithreaded
environments.
