I've implemented a DDPG algorithm in Pytorch and I can't figure out why my implementation isn't able to solve MountainCar. I'm using all the same hyperparameters from the DDPG paper and have tried running it up to 500 episodes with no luck. When I try out the learned policy, the car doesn't move at all. calypso system 前立腺
