3. Convert NumPy Matrix to Array Using ravel() Thenumpy.ravel()function is used to create a contiguous flattened array from a given input array. This function returns a flattened one-dimensional array, meaning it collapses the input array into a flat, contiguous sequence. 3.1 Syntax of ravel(...
Convert byte array back to NumPy arrayIn numpy, we can convert a numpy array to bytes using tobytes() function. To convert it back into a numpy array, we use numpy.frombuffer().For this purpose, we will first create a numpy array and convert it into a byte array using tobytes() ...
