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.

<p>
|

|
|
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.
