An implementation of DQN algorithm via pytorch to use multiple gpu in a single node. I use DataParallel API for this purpose.
The REINFORCE/Actor-Critic algorithm works only with CartPole.
The general_dqn is a general DQN algorithm for any non-image env, and it is possible to define fully connected layer of any size.
The reinforce_AC_CartPole_torch notebook, includes a naive implementation of REINFORCE, REINFORCE with Reward to Go, AC, and AAC algorithms.
