Sphinx autodoc fails to import module

Question

I'm trying to document a project using Sphinx, and am running into an issue where only some modules are being imported from a folder. My project structure looks like this:

Project
|
|--Main
|    |--Scripts
|          __init__.py
|          libsmop.py
|          conv_table.py
|          f_discrim.py
|          recipes.py
|          ...

When I try to run make html, libsmop and recipes are imported without any issue, however conv_table and f_discrim get the following error:

WARNING: autodoc: failed to import module u'conv_table' from module u'Scripts'; the following exception was raised:No module named conv_table

I don't think it's my config file because it's finding all of the files when I run sphinx-apidoc -o _rst Main/Scripts and I've confirmed that they appear in the resulting Scripts.rst file.

Why is autodoc finding some modules but not others?

Edit: conv_table.py is of this form:

import re
import numpy as np

"""
conv_table dictionary at the bottom of this file maps from matlab functions
to their python equivalents.
"""

def get_args(line,separator=",", open_char='(', close_char=')'):
    """Returns the arguments of line

    >>> get_args('ones(3,1,length(arr))')

...
< a bunch of function definitions>
...

conv_table = {... < a very big dictionary > ...}

Answer 1

Since your autodoc is picking up some of the modules, it may be because the dependencies of the failed modules are either 1) not imported correctly or 2) not installed under your python environment. You will want to check if all the import statements work within your failed modules.
