================================================

cuda >= 9.0 

cudnn >= 7.0

opencv  https://sourceforge.net/projects/opencvlibrary/

The Arcade Learning Environment (ALE)  https://github.com/mgbellemare/Arcade-Learning-Environment

make

bin/cytonRl --env roms/breakout.bin --mode train --saveModel model/model --showScreen 1

or faster training as,

bin/cytonRl --env roms/breakout.bin --mode train --saveModel model/model --showScreen 0

The second command turn off the game window which makes the program run much faster. The game window can be brought back by creating a empty file "mode/model.screen", or turned off again by deleting that file.

bin/cytonRl --mode test --env roms/breakout.bin --loadModel model/model.100000000 --showScreen 1

or using our trained model as

bin/cytonRl --mode test --env roms/breakout.bin --loadModel model-trained/model --showScreen 1

or faster test as

bin/cytonRl --mode test --env roms/breakout.bin --loadModel model-trained/model --showScreen 0

The game window can be brought back by creating a empty file "mode/model.screen", or turned off again by deleting that file.
