Vpython安装后奇怪的未来警告错误

Question

首先我安装了Python 2.7.6（Windows，32位版本），然后安装了numpy 1.9.1，然后安装了VPython 6.10。在那之后，我收到了这个错误：

Python 2.7.6 (default, Nov 10 2013, 19:24:18) [MSC v.1500 32 bit (Intel)] on win32
Type "copyright", "credits" or "license()" for more information.
>>> import visual

Warning (from warnings module):
  File "C:\Python27\Lib\site-packages\visual_common\materials.py", line 70
    self.__setattr__(key, value)
FutureWarning: comparison to `None` will result in an elementwise object comparison in the future.

>>> ================================ RESTART ================================
>>>

出了什么问题？

Answer 1

快速Google for＆＃34; FutureWarning：与None的比较将导致将来进行元素对象比较。＆＃34;
