The OpenAI Gym can be paralleled by the bathEnv.py, which makes the training faster.

You can use the following command to choose which DQN to use:

python main.py --is_double 1 --is_duel 1 --is_per 1 --is_distributional 1 --is_noisy 1 --num_step 3

The output looks like:

Number_of_frame    mean_max_Q    average_reward    variance_reward

DQN, Double DQN, and Duel DQN parts are implemented by Ben and me. https://github.com/bparr/10703

The best and most concise implement of Distributional RL loss function in Tensorflow by far in the world!!! Better and faster than all others' implements that I can find.
