This speeds up trajectory collection because extract_info_at_index() in t2t/.../trjaectory.py now index numpy.array instead of DeviceArray and it's about 10000x times faster. I've benchmarked using command: python trax/rl_trainer.py --config_file=trax/rl/configs/ppo_acrobot.gin --train_batch_size=32 --output_dir=/tmp/ppo_acrobot --alsologtostderr Epoch time goes down from 84s to 9s per iteration.
