KeyError visit_node question #103

Closed shunana closed 3 years ago

shunana commented 3 years ago

Hi I have a question. I am using the vrpy to solve a VRP problem, so far I have created a graph as guided, then when I try to solve the problem I get the following error.

keyerror_visit_node

What does that exactly referer to ? As I can see it is connected to other nodes, and sink. Hope that you can help, thanks

Wow that is a funky node name ☺️ Try using a name without any special characters, including ´- ´ and see if that does the trick.
