i got the same error with you, did you solve it?

[bbitmaster]

I wrote this library over a year ago, and it worked with ALE back then, since then it has been included as part of the official ALE repository.

I'm guessing ALE has changed it's API slightly since then, and this interface is no longer compatible with the latest ALE.

I suggest you either

1. Use the python interface that is included as part of ALE
2. Use an older ALE if you want to use this version of the interface
   or 3. Feel free to fix this error and open a pull request. I'll test and approve it.

Thank you, but when i use python interface i got this:

>>>from ale_python_interface import ALEInterface
>>>ale = ALEInterface()

A.L.E: Arcade Learning Environment (version 0.5.1)

Use -help for help screen.
Warning: couldn't load settings file: ./ale.cfg

[jeremyfix]

You need to copy the ale.cfg file in the directory where you are running your python interpreter ?

This file is provided by the Arcade-Learning-Environment sources.

[zwglory]

i copy the ale.cfg and the game rom file into my project, it worked!
Thank you!

[alexisylchan]

thanks @jeremyfix I copied Arcade_Learning_Environment/ale_python_interface to ale_python_interface/ale_python_interface as well to make the build work
