Hi Pablo,
I understand that you want to multiply two matrices without getting any error.
To perform element wise multiplication on any given two matrices, their indexes must be same or be compatible. For more information on the compatibility of the matrices, refer to the following documentation:
In your case, the sizes of the matrix ‘y’ and ‘z’ are (1x192016) and (1x8) respectively making the sizes incompatible. To avoid the error, make sure that the array sizes are same or compatible as mentioned in the above documentation.
