Hello all, Can an m x n x k matrix be multiplied with n x k matrix? Looking at the Numpy doc page 46 ( https://docs.scipy.org/doc/numpy-1.11.0/numpy-user-1.11.0.pdf), it should work.
It says the following: A (3d array): 15 x 3 x 5 B (2d array): 3 x 5 Result (3d array): 15 x 3 x 5 But, the rule did not work for me. Here's my toy example: >>> a = np.arange(3*4*5).reshape(3,4,5) >>> b = np.arange(4*5).reshape(4,5) >>> np.dot(a, b) Traceback (most recent call last): File "<stdin>", line 1, in <module> ValueError: shapes (3,4,5) and (3,5) not aligned: 5 (dim 2) != 3 (dim 0) Am I miss reading something? Thank you in advance!
