WitrynaFor convenience we will reshape images of shape (32, 32, 3) into numpy array of shape (3072, 1). By using '-1' we say that number of column is unknown, but number of rows is known. By using '.T' we're transposing each image and making their data arranged in columns. Consider following part of the code: (related file: Logistic_Regression.py) Witrynanumpy.reshape(a, newshape, order='C') [source] #. Gives a new shape to an array without changing its data. Parameters: aarray_like. Array to be reshaped. newshapeint or tuple of ints. The new shape should be compatible with the original shape. If an integer, then the result will be a 1-D array of that length. One shape dimension can be -1.
