Hi, I just want to know why we should specifically use the function
X_flatten = X.reshape(X.shape[0], -1).T
as the solution for the problem. For example when I use
(1)
train_set_x_flatten = train_set_x_orig.reshape(num_pxnum_px3,m_train)
where previously:
m_train = train_set_x_orig.shape[0]
num_px = train_set_x_orig.shape[1]
instead of
(2)
train_set_x_flatten = train_set_x_orig.reshape(train_set_x_orig.shape[0], -1).T
to reshape the matrix. Both functions will reshape the matrix into the size of (12288, 209) however the first few elements are different when looked using train_set_x_flatten[0:10,1] command.
The function (1) when I type will result in
array([31, 34, 79, 46, 33, 69, 36, 20, 67, 31], dtype=uint8)
But the function (2) will result in
array([196, 192, 190, 193, 186, 182, 188, 179, 174, 213], dtype=uint8)
Does anyone know the difference between both functions? Please let me know. Thank you
