numpy row to column
You can use np.flatten on your array: >>> x array([[1], [2], [3], [4], [5]]) >>> x.flatten() array([1, 2, 3, 4, 5]). ,The easier way is vector1 = matrix1[:,0:1]. For the reason, let me refer you to another answer of mine: When you write something like a[4] , that's accessing the ... ,(To change between column and row vectors, first cast the 1-D array into a matrix object.)
