我尝试在模拟器Webots(7.0.3)中导入numpy ，直到主管恢复模拟几次才成功使用。它出来这些错误信息：

Traceback (most recent call last):
  File "PyController.py", line 39, in <module>
    from numpy import *

    self[k] = dict[k]
   File "C:\Python27\lib\os.py", line 422, in __setitem__
    putenv(key, item)
ValueError: the environment variable is longer than 32767 bytes

revert 函数是监督机器人的原始函数，可以在 Webots 模拟器中调用：

supervisor.simulationRevert()

任何机构都可以帮我解决这个问题吗？谢谢！
