[Numpy-discussion] Problem with loadtxt

I have a text file called 'blah' that contains only the following line:


I want to load these into a numpy array as unit64's.  The following script
demonstrates my problem:

import numpy as np

with open('blah', 'r') as f:
    x = np.loadtxt(f, delimiter=',', dtype=(np.uint64, np.uint64))

with open('blah', 'r') as f:
    for line in f:
        print line

print x

The output I get is:


[5399354557888517120 5399354557888517120]

Am I doing something wrong?

Thanks for your help,
