无法运行Pybrain教程

Question

我正在尝试运行其中一个教程,这就是我得到的:

$ python rl.py
Traceback (most recent call last):
  File "rl.py", line 22, in <module>
    from pybrain.rl.environments.mazes import Maze, MDPMazeTask
  File "/Library/Python/2.7/site-packages/PyBrain-0.3.1-py2.7.egg/pybrain/rl/environments/mazes/__init__.py", line 3, in <module>
    from pybrain.rl.environments.mazes.tasks.__init__ import *
  File "/Library/Python/2.7/site-packages/PyBrain-0.3.1-py2.7.egg/pybrain/rl/environments/mazes/tasks/__init__.py", line 1, in <module>
    from pybrain.rl.environments.mazes.tiger import TigerTask
ImportError: No module named tiger

它安装成功,不知道为什么它无法加载自己的模块？

您需要更改文件:pybrain/pybrain/rl/environments/mazes/tasks/__init__.pyas:

from pybrain.rl.environments.mazes.tiger import TigerTask

至:

from pybrain.rl.environments.mazes.tasks.tiger import TigerTask
