You still would not be able to load a numpy array > 2 Gb. Numpy memory model needs one contiguously addressable chunk of memory for the data, which is limited under the 32 bits archs. This cannot be overcome in any way AFAIK. You may be able to save data > 2 Gb, by appending several chunks < 2 Gb to disk - maybe pytables supports this if it has large file support (which enables to write files > 2Gb on a 32 bits system). cheers, David _______________________________________________ NumPy-Discussion mailing list NumPy-Discussion@scipy.org http://mail.scipy.org/mailman/listinfo/numpy-discussion
