I am running the exact same code on both windows and mac, with python 3.5 64 bit.
On windows, it looks like this:
>>> import numpy as np >>> preds = np.zeros((1, 3), dtype=int) >>> p = [6802256107, 5017549029, 3745804973] >>> preds[0] = p Traceback (most recent call last): File "<pyshell#13>", line 1, in <module> preds[0] = p OverflowError: Python int too large to convert to C long
However, this code works fine on my mac. Could anyone help explain why or give a solution for the code on windows? Thanks so much!

Answer
You’ll get that error once your numbers are greater than sys.maxsize
:
>>> p = [sys.maxsize] >>> preds[0] = p >>> p = [sys.maxsize+1] >>> preds[0] = p Traceback (most recent call last): File "<stdin>", line 1, in <module> OverflowError: Python int too large to convert to C long
You can confirm this by checking:
>>> import sys >>> sys.maxsize 2147483647
To take numbers with larger precision, don’t pass an int type which uses a bounded C integer behind the scenes. Use the default float:
>>> preds = np.zeros((1, 3))
