Relative path in source/MulensModel/data

[jenniferyee]

L51-55 of init.py are
"""
path_1 = path.join(MODULE_PATH, 'data')
if path.isdir(path_1):
DATA_PATH = path_1
else:
DATA_PATH = path.join(path.dirname(file), 'data')
"""

This points to source/MulensModel/data

That file points to ../../data

This is a relative path, which is generally bad practice, and it seems the reason is that it doesn't always work. For instance, when MulensModel is installed via Google Colab, it can't find interpolation_table_b0b1_v3.dat.

Why is DATA_PATH set up this way? Why can't we set it up without the relative paths?

This if statement is there because of different paths for pip install and PYTHONPATH installations. I'm guessing Google Colab uses pip install or similar.
Right now I don't know how to set it up without path.dirname().

@jenniferyee Ok, a quick fix for the user would be to download a release from github, move the data directory, change path in __init__.py and run installation based on local files.
