Shapes 20 and 1 not aligned: 20 dim 0 1 dim 0
WebbYou don't really need a dot product for that, numpy can find its way with a simple multiplication: halved = val_by_constants * .5. Finally, you want to apply a tanh function … For matrix multiplication (which is what the @ operator does), you need the inner dimensions of the matrices in question to match. That is, you can multiply a 20 x 1 matrix by a 1 x 2 matrix, but not by a 2 x 1 matrix. This is not a numpy specific thing, it's just a basic fact of matrix arithmetic.

WebbThey can be summarised as follows: When a ray of light hits the boundary between two transparent materials, it is divided into a reflected and a refracted ray. The law of reflection says that the reflected ray lies in the plane of incidence, and the angle of reflection equals the angle of incidence.
