  1. @jcasman and I are translating the documentation to help us practice using github fork and pull requests
  2. we’re using pydoc to convert the Python docstrings into html for pytheta.py. I’m still thinking of how to have both the Japanese and English in the same document.
  3. I’ve installed Ubuntu 16.04 on a separate SSD and have replicated your environment. I am still getting errors. I will test this more
  4. I am using pip and pipenv to create a Pipfile of the specific Python version and module used
  5. I installed the same version of gphoto2 as you did by compiling from source

I’m going to test the module functions individually next.
