ImportError: No module named glass

Installing in py2.7 from pip in Azure notebooks environment gives an error at first base:

!pip2 install opticspy
from opticspy.ray_tracing import *

returns:

Please check again. It may fixed

Thanks, seems to work for me now in py 2.7

However, I get an error even quicker in py3.6, which the update to the repo README suggests should work?

!pip3.6 install --upgrade git+https://github.com/Sterncat/opticspy.git
from opticspy.ray_tracing import *

returns:

In Py2.7 I also get an error later on in the http://sterncat.github.io/files/Real_Ray_Tracing.html demo script:

Check if the glass folder in the code and in your opticspy folder. Maybe need add manually.

Ah, it's not copied into the py package folder.

Looking at https://github.com/Sterncat/opticspy/blob/master/setup.py there was some history of installing the package explicitly? Whatever the case, it doesn't seem to be being installed in my Py2.7 environment.

Should the files be installed as - and referenced as - data files? https://docs.python.org/2.7/distutils/setupscript.html#installing-additional-files (I'm not v. familiar with python package setup scripts...)

I think just download it from github and drag it into the folder. I will try to check it later. Thank you for finding this!
