This would happen when, e.g, you try to multiply a 20x20 value with a 20x10 value (how your nodes end up with something like this I do not know...) The shape of each axis must be equal, or else one can be equal to 1.

What does the error message 'arguments from operator * have incompatible shapes while getting result' mean? (last edited 2007-02-21 02:29:34 by TonyWillis)
