could anyone on 32bit system with fresh numpy (1.7.1) test following:
> wget -nc http://www.onerussian.com/tmp/data.npy ; python -c 'import numpy as
> np; data1 = np.load("/tmp/data.npy"); print np.sum(data1[1,:,0,1]) -
> np.sum(data1, axis=1)[1,0,1]'
0.0
because unfortunately it seems on fresh ubuntu raring (in 32bit build only,
seems ok in 64 bit... also never ran into it on older numpy releases):
> python -c 'import numpy as np; data1 = np.load("/tmp/data.npy"); print
> np.sum(data1[1,:,0,1]) - np.sum(data1, axis=1)[1,0,1]'
