   I'm not familiar with your package, so I'm sure others will be able to
help give more details on why this is set up this way. But, let me tell you
what an __init__.py file is. Also, I can show you how to get started in the
short term.

    A module in python is almost like a directory (on your python path). For
example, lets say we have a directory like this:


Now, it'd be very "cool" if I could do this:

from my_cool_module.my_cool_file1.py import my_cool_function

(okay forgive my bad naming and overuse of the word 'cool' :)

This won't work without a __init__.py file inside:


You can almost think of it as a "directory" of your module files. Now, the
file doesn't have to have any python code it it (but it can if you really
want to do some special things). It only has to exist.

With all that said, I'm not sure what your __init__.py.in file contains. It
may be an empty file. However, to use any module, you need to have an
__init__.py file.

So, it may be as simple as:

cp __init__.py.in __init__.py

Or, if there's nothing in the file, simply creating a blank one will let you
move on:

touch __init__.py

This doesn't get you totally out of the weeds. But, hopefully it helps a

Warmest Regards,

Glen Jarvis
