hi! Thanks for open sourcing your work! I am not sure if you are were, VRPy does not seem to work on M1.

when I attempt 

from vrpy import VehicleRoutingProblem

On MacOs Monetrey with M1 processor I get

Traceback (most recent call last):
  File "/Users/piotrzakrzewski/code/vrp/main.py", line 2, in <module>

Seems to be caused by cspy?

Just uploaded a wheel for Python 3.10. Sorry, there is an issue with the build actions (it is mentioned here)
