Installed Eggs

System Path

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.
