I am trying to implement the algorithm in the paper

https://www.cmu.edu/epp/patents/events/aaai21/aaaicontent/papers/training-integer-valued-neural-networks-with-mixed-integer-programming.pdf

As per equation 16 I need to put a constraint that sum of O^k is 1. The question is how can I implement that constraint?

If I just do self.m.addConstr(sum(O)==1)

I get the error TypeError: 'Var' object is not iterable

  The object was not iterable and hence the error. Problem is resolved.
