Hi,
I have a text file called 'blah' that contains only the following line:
5399354557888517312,5399354557888517312
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:
5399354557888517312,5399354557888517312
[5399354557888517120 5399354557888517120]
Am I doing something wrong?
Thanks for your help,
Scott
