Reshape 2d to 1d
Webar.reshape(ar.shape[0],-1) That second input to reshape: -1 takes care of the number of elements for the second axis. Thus, for a 2D input case, it does no change. For a 1D input case, it creates a 2D array with all elements being "pushed" to the first axis because of ar.shape[0], which was the total number of elements.
