Apparently, a[0][0] is not a ShortestNull because otherwise, the .__mul__ would have the positional argument, > 'other' equal to a[0][0]. > > What am I missing? > a=np.array([[ShortestNull,ShortestPath(12)],[ShortestPath( 12),ShortestNull()]],dtype=object) You didn't instantiate ShortestNull but passed the class object instead. -- Robert Kern
