I don't know how to fix this without changing __mul__ to pointwise mult which would break things. I'm submitting a patch for the sparse.multiply 'inconsistent shapes' bug that you noted. so it should work now. WebBasic operations on numpy arrays (addition, etc.) are elementwise This works on arrays of the same size. Nevertheless, It’s also possible to do operations on arrays of different sizes if NumPy can transform these arrays so that they all have the same size: this conversion is called broadcasting. The image below gives an example of broadcasting: tripp lite 18u rack
