ValueError: There is not enough capacity to cover update_horizon and stack_size.

Hello,

I got an un-explainable issue related to `dopamine`

My current setup for infrastructure is `T4` - 70GB memory with minimizing configurations (Less than 10 for almost every parameter).

Here is an issue:

```
ValueError: There is not enough capacity to cover update_horizon and stack_size.
In call to configurable 'WrappedPrioritizedReplayBuffer' ()
In call to configurable 'DQNAgent' ()
In call to configurable 'RainbowAgent' ()
In call to configurable 'create_agent' ()
In call to configurable 'Runner' ()
In call to configurable 'create_runner' ()
```

What I understand is that there isn't enough memory. I test this hypothesis by a simple starting experiment. Nonetheless, it still yields the same error.

Any comment would be very helpful. Thanks
