Loss during training:

Number of durations per Episode:

Usage:

• To run the project, you need to add your configurations into the folder configs/ as fround here
• sh run.sh
• To run on a GPU, you need to enable cuda in the config file.

Requirements:

• Pytorch: 0.4.0
• torchvision: 0.2.1
• tensorboardX: 0.8

Check requirements.txt.

Future Work:

• Test DQN on a more complex environment such as MS-Pacman
