AttributeError: 'module' object has no attribute 'DefaultRoutingSearchParameters'

Question

I have installed the ortools exactly as mentioned in this link.

After that, I copied vehicle routing problem from the documentation and tried to execute.I am using python 2.7.12 in my system.

I ended up with the below error:

   >>python or_test.py 
      Traceback (most recent call last):
      File "or_test.py", line 120, in <module>
      main()
      File "or_test.py", line 52, in main
     search_parameters = pywrapcp.DefaultRoutingSearchParameters()
   AttributeError: 'module' object has no attribute 
  'DefaultRoutingSearchParameters'

Answer 1

Based on the example from the repo, you can get default parameters like this instead:

 search_parameters = pywrapcp.RoutingModel.DefaultSearchParameters()
