planning on it, stay tuned! :)

Great, Can I ask how you do tuning and finding the optimal hyperparameters? By grid search?

for the configs we've been releasing with dopamine we use the published settings. however, for DQN and C51 we used some of the settings from Rainbow when it was published (although we do provide configs with the settings used when each of those agents was published).

Thanks.

@GoingMyWay how'd you decide on Dopamine for distributional RL? What are your thoughts on DeepMind's acme?

@GoingMyWay how'd you decide on Dopamine for distributional RL? What are your thoughts on DeepMind's acme?

Hi, Dopamine has implemented C51, IQN, Rainbow and it is stable now, you can easily implement other Q-based distributional RL. For ACME, I did not use it before, it is very new, so maybe not stable and has some unfound bugs.

There are many mature frameworks like ACME, for example, ray.io, it also provides RL APIs for fast RL algorithm implementation.

coming back to the original question on this thread, we now have a JAX implementation of QR-DQN: https://github.com/google/dopamine/blob/master/dopamine/jax/agents/quantile/quantile_agent.py

Great, @RylanSchaeffer You can try Dopamine.
