Web1 Answer Sorted by: 23 If X and beta do not have the same shape as the second term in the rhs of your last line (i.e. nsample ), then you will get this type of error. To add an array to a tuple of arrays, they all must be the same shape. I would recommend looking at the numpy broadcasting rules. Share Improve this answer Follow WebYou can add that extra dimension as follows: a = np.array (a) a = np.expand_dims (a, axis=-1) # Add an extra dimension in the last axis. A = np.array (A) G = a + A Upon doing this and broadcasting, a will practically become [ [0 0 0 0 0 0] [1 1 1 1 1 1] [2 2 2 2 2 2] [3 3 3 3 3 3]]
