Why is sphinx automodule not showing any module members?

If your class is imported into __init__.py you may also need :imported-members: like so:

.. automodule:: myproject
   :imported-members:
   :members:
   :undoc-members:
   :show-inheritance:

The main module is in the myproject package. In order to document main, you need the following:

.. automodule:: myproject.main
   :members:
