This works. A big array of eight bit random numbers is constructed: import numpy as np
spectrumArray = np.random.randint(0,255, (2**20,2**12)).astype(np.uint8) This fails. It eats up all 64GBy of RAM: spectrumArray = np.random.randint(0,255, (2**21,2**12)).astype(np.uint8) The difference is a factor of two, 2**21 rather than 2**20, for the extent of the first axis. -- David P.
