Numpy Array To Bytes

Numpy Array To Bytes. Howto make python list from numpy.array?. This function creates another copy of the initial array with the specified data type, float in this case, and we can then assign this copy to a specific identifier, which is convertedarray.

The bytearray is coming out of a udp socket so first i convert two consecutive bytes into an int16 using struct.unpack, and then convert it a numpy array using np.asarray. The data produced by this method can be recovered using the function fromfile ().
