The Retro Learning Environment (RLE) -- a learning framework for AI

DEPRECATED

RLE has been succeeded by the wonderful work of the folks at OpenAI under their repository Gym-retro. Since they now support all the consoles and games that we supported and most of our features, there's no reason to maintain this one.

Retro-Learning-Environment

A learning framework based on the Arcade Learning Environment (ALE) and Libretro (Stella for Atari and SNES9X for the Super Nintendo Entertainment System).

The environment provides an interface to training and evaluating AI algorithms against different console games using its screen as input.

The currently supported games can be found in the src/games/supported directory . Some popular games include: Mortal Kombat, Super Mario All Stars, F-Zero, Castle Wolfenstein and Gradius III.

A paper is available for RLE at http://arxiv.org/abs/1611.02205. If you use RLE in your publication, please use the following BibTex entry:

@article{bhonker2016playing,
  title = {Playing SNES in the Retro Learning Environment},
  author = {Bhonker, Nadav and Rozenberg, Shai and Hubara, Itay},
  journal = {arXiv preprint arXiv:1611.02205},
  year = {2016}
}

Quick Start

Install main dependencies:

sudo apt-get install libsdl1.2-dev libsdl-gfx1.2-dev libsdl-image1.2-dev cmake

To install as a Gym environment:
Go to the gym-rle repository and follow the instructions there.

To install the python interface:
Either install via PyPi:

$ pip install rle-python-interface

or by cloning the repository and running the following:

$ pip install .
or
$ pip install --user .

To use the shared_library interface:

$ mkdir build && cd build
$ cmake -DUSE_SDL=ON -DBUILD_EXAMPLES=ON ..
$ make -j4

To install the lua (Torch) interface, the additional alewrap module is required:

luarocks install https://raw.githubusercontent.com/nadavbh12/Retro-Learning-Environment/master/ale-2-0.rockspec
luarocks install https://raw.githubusercontent.com/nadavbh12/alewrap/master/alewrap-0-0.rockspec

DQN Implementations Using RLE

• A fork of @spragunr's DQN implementation in Python.

Acknowledgements

• @mgbellemare for his work on ALE and his useful advice.
• @Alcaro and the @libretro community for their assistance in incorporating their work into our framework.

retro-learning-environment's Issues

deep_q_rl error

After I ran the following command,

$ python run_nips.py --rom mortal_kombat.sfc --core snes

I encountered this error,

[Question] What is the core_file in the python example?

Hi, I've been trying to run the example_python file, and I was stuck with the core_file parameter, I was wondering which core_file is it? And is it a file that I should download from elsewhere? At first i thought it was a file inside the lib itself, but I couldn't get myself to find it.
Also I was considering to use this API in an academic project, so I would like to know if is there any documentation available .
Thanks in advance.

Python3 compatability

Hello,

you are using ctypes, and python2 would use bytestrings, however python3 uses unicode and strings are sent as such. Therefore various errors like ctypes.ArgumentError: argument 2: <class 'TypeError'>: wrong type will occur.

Python quick start

I have troubles using the python interface.
Can you give a more detailed walkthrough of how to get it to work?

After
mkdir build && cd build
it cannot find the CMakeLists.txt file. Should I just build it from the root?

In the python_example.py I need to import the interface like this:
from rle_python_interface.rle_python_interface import RLEInterface
In order to get RLEInterface.

But when I run the file, I get
File "/home/noju/Documents/Retro-Learning-Environment/rle_python_interface/rle_python_interface.py", line 108, in setInt rle_lib.setInt(self.obj, key, value) ctypes.ArgumentError: argument 2: <class 'TypeError'>: wrong type

Snes9X

Hello, i would like to know if there is some way to set the options of the snes9x emulator, such as background removal, filters disabling and fast-foward.

I did rename the rom file to agree with the name in the header file.

Please give me some advices?

In Street Fighter II, rle.game_over() automatically set to true in the middle of the game

Thanks again for the great work. In Street Fighter II. I notice that the game will automatically terminate in the middle of the episode. To be specific: rle.game_over() will automatic turn to true in the middle of the game. I looked at src/games/supported/StreetFighterII.cpp but I didn't aware where the terminal condition is set. Could you please help?

Trouble installing on AWS

Hi Nadav,

Sorry to bother you with this again. I'm now trying to install RLE on AWS EC2. I get the following errors. Do you have any tips? Thanks.

How to run python example on Linux

Hi, I've got some troubles with the given example in:

~/doc/examples

I try to run:

python_example.py path_to_game_rom

But it fails with issues wrt argv[2], where I should provide some core_file (*.so)

I try again:

python_example.py path_to_game_rom path_to_librle_c.so

But it fails again with this error:

Failed to load symbol 'retro_init'': ../../rle_python_interface/librle_c.so: undefined symbol: retro_init

It seems to that there should be some corrections wrt symbols
(it can be linux specific as previous commit to setup.py from my buddy)

fix setup.py

Please change
cmake_args = ' -DBUILD_EXAMPLES=OFF -DBUILD_PYTHON=ON'
to
cmake_args = ' -DBUILD_EXAMPLES=OFF -DBUILD_PYTHON=ON -DUSE_SDL=ON'
and make the world a better place. Great Work BTW!

trying to launch python example, get an error ImportError: cannot import name 'RLEInterface'

Can not get SDL display to work with python example.

Hi, I'm having issues getting the SDL display to work for the python implementation. I feel I've followed steps correctly by looking at the original docs as well as a few solved solutions but I'm still not having any luck. Here is what I have done:

1. Running Ubuntu 16.04
2. sudo apt-get install libsdl1.2-dev libsdl-gfx1.2-dev libsdl-image1.2-dev cmake
3. added -DUSE_SDL=ON to the cmake args in setup.py
4. ran "pip install ."
5. changed "USE_SDL = False" to "USE_SDL = True" in python_example.py
6. python doc/examples/python_example.py roms/classic_kong.smc snes
7. Output:

It runs just fine, however, there is no graphical display.

python_interface gives wrong game screen dimensions

• Ubuntu 16.04
• using python interface to work with RLE.
• I used the option "-DUSE_SDL=ON" in setup.py to see actual game screen
• I run "sonic_the_hedgehog"

I tried to get grayscale game screen by calling the following method of the python interface:
def getScreenGrayscale(self, screen_data=None)
, and there was two problems (, which is actually coming from one source)

It gave me an array of grayscale pixel data, however, the screen was totally distorted.
I played with it for a while, I noticed that it's because the method initializes screen_data variable with wrong number of pixels in a row and col when I did not pass screen_data variable.
I could guess right width (640 px), and able to get clean data by passing screen_data with right dimensions.

Also, I noticed another problem: Even though I pass screen_data variable initialized in right size, the screen_data array is not fully filled, but have many zeros in the tail.

When getScreenGrayscale is called in the python interface, it calls
void getScreenGrayscale(RLEInterface *rle, unsigned char *output_buffer) in rle_c_wrapper.cpp which calls :
size_t w = rle->getScreen().width();
size_t h = rle->getScreen().height();

The cause of the problem is that the last two methods gives wrong values.
I could pass screen_data numpy matrix to the python interface method, but when c method received the matrix, the matrix is viewed as an one dimensional pointer variable, which does not have dimensional information, and the right dimension that even explicitly specified in python-side could not passed to c-side.

For the same reason, the following methods in rle_c_wrapper.h also does not work properly.
int getScreenWidth(RLEInterface *rle){return rle->getScreen().width();}
int getScreenHeight(RLEInterface *rle){return rle->getScreen().height();}
, which is being used in following methods in rle_python_interface.py
def getScreenRGB(self, screen_data=none)
def getScreenGrayscale(self, screen_data=none)

I made a method
void getScreenGrayscaleWithDims(RLEInterface*, unsigned char*, size_t width, size_t height)
and used it instead of
void getScreenGrayscale(RLEInterface *rle, unsigned char *output_buffer)
in order to specify dimensions explicitly
, and it works fine.
I could get screen_data in undistorted and right size with fully filled pixel data.

Though ultimately Screen.width(), height() methods need to be fixed, let me send a pull request if it is looking good.

Install RLE on CentOS Linux release 7.2.1511

I am trying to install rle on centos with
pip install rle-python-interface,

but always failed because of
/tmp/pip-build-mm00sro_/rle-python-interface/src/environment/RetroAgent.cpp:10:28: fatal error: alsa/asoundlib.h: No such file or directory #include <alsa/asoundlib.h>

I have done a few research on installing libasound2 on centos, but with no luck. The install log is attached here install.txt, any idea how to overcome this?

game_over() set to True when Mario gets a Mushroom in Super Mario World

Whenever Mario hits a mushroom (and possibly any other item) the game returns True to game_over().

Help Needed, Resulted Trained agent?

1. how to add new game?
2. where is final result of trained agent?
3. How to switch dqn with ddqn d-ddqn?

I am all new in this So your help will be highly appreciated. Thanks, Looking forward.

Can't find documentation about DQN in this environment

I run environment through python interface from doc/example like
$ python python_example.py path_to_rom path_to_core
I modified the code set episode to 2000 and the training was running for 1 day but the agent is not learning.
I searched the code but couldn't find the module for DQN.
Please kindly Help.
