Hello there,

I’ve been trying to run the tuned examples on DQN.

> <https://github.com/ray-project/ray/blob/master/rllib/tuned_examples/dqn/atari-duel-ddqn.yaml>

The only thing I’ve changed is the replay buffer size to 150k samples.

The results for Breakout aren’t anything near the scores provided by the results page.  
Any pointers to what could be going wrong?

Sorry for now answering this earlier. Let’s keep the discussion in [Trouble reproducing results with DQN](https://discuss.ray.io/t/trouble-reproducing-results-with-dqn/9443).
