Memory error during training

Am getting this:

MemoryError: In call to configurable 'WrappedPrioritizedReplayBuffer' (<function WrappedPrioritizedReplayBuffer.__init__ at 0x7f07a046dd90>) In call to configurable 'DQNAgent' (<function DQNAgent.__init__ at 0x7f07a046c598>) In call to configurable 'RainbowAgent' (<function RainbowAgent.__init__ at 0x7f07a046d400>) In call to configurable 'create_agent' (<function create_agent at 0x7f07a0483d08>) In call to configurable 'Runner' (<function Runner.__init__ at 0x7f07a0484268>) In call to configurable 'create_runner' (<function create_runner at 0x7f07a04840d0>)

have tried adding ```
–gin_bindings=WrappedReplayBuffer.replay_capacity=1000


ubuntu VM has 7.5Gb RAM with TeslaT4 GPU

Any help much appreciated
