Solution :

The issue is because the 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

Please confirm this by checking:

>>> import sys >>> sys.maxsize 

To resolve the issue use the default float:

>>> preds = np.zeros((1, 3))
