Python numpy ValueError: operands could not be broadcast together with shapes

3.1K Asked by Aryangupta in Python , Asked on Apr 10, 2021

In numpy, I have two "arrays", X is (m,n) and y is a vector (n,1)

using

X*y

I am getting the error

ValueError: operands could not be broadcast together with shapes (97,2) (2,1)
When (97,2)x(2,1) is clearly a legal matrix operation and should give me a (97,1) vector

Answered by Aryan gupta

While getting error operands could not be broadcast together with shapes Use the below mentioned code to get rid of the error:-

import numpy 

numpy.dot(numpy.ones([97, 2]), numpy.ones([2, 1])).shape

Note: operands could not be broadcast together exception means that the arrays have incompatible shapes.
