问题描述
我在 windows 和 mac 上运行完全相同的代码，使用 python 3.5 64 位.
I am running the exact same code on both windows and mac, with python 3.5 64 bit.
在 Windows 上，它看起来像这样:
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
但是，这段代码在我的 mac 上运行良好.任何人都可以帮助解释原因或为 Windows 上的代码提供解决方案吗?非常感谢！
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!
推荐答案
一旦你的数字大于 sys.maxsize，你就会得到这个错误:
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
您可以通过检查来确认:
You can confirm this by checking:
>>> import sys
>>> sys.maxsize
2147483647
要获取更高精度的数字，请不要传递在后台使用有界 C 整数的 int 类型.使用默认浮点数:
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))
