TypeError: __hash__method should return an integer in self.children[action] = ActionNode(self,action)

[jtsere]

I get this error when I run the code. Any suggestions?

Can you elaborate a bit on what exactly you tried and give the full stack trace etc.

I tried to run the mcts on the top of the simple maze example ([3,3]) as described in the ReadMe file. The error occurs when executing this line of code : root = StateNode(parent=None, state=MazeState([0, 0]))

__hash__'s return should be int type.

Casting it before return works for me.

...
    def __hash__(self):
        return int(10 * self.pos[0] + self.pos[1])

...
    def __hash__(self):
        return int(10*self.move[0] + self.move[1])
