Cannot import LabelTimeBoardingsAndRoute

[leoferres]

Hi! Thanks for your software. I was wondering why I cannot import

from gtfspy.routing.node_profile_analyzer_time_and_veh_legs import NodeProfileAnalyzerTimeAndVehLegs

it gives me a

ImportError: cannot import name 'LabelTimeBoardingsAndRoute'

Any idea what I may be doing wrong? The complete traceback is as follows:

Hi and thanks for testing out our code!

I was able to replicate this bug. For some reason I found that the import failed when using Python 3.6, but succeeded when using Python 3.5. So if using Python 3.5 is an option for you, that would probably be a quick fix for this.

I have no clear idea why the import does not work with Python 3.6, and unfortunately can not promise when I would have the time to dwell into this problem.

For the time being, I changed the recommended Python version to Python 3.5 in the package README file (in commit a5e1e0b ).

Great! Meanwhile, I tried it with py3.5 and it worked fine. Thanks!

Great! Let us know if you encounter further problems or something is unclear, as the package has not yet had that many users.
