 This repository contains the [Meta-World](https://arxiv.org/abs/1910.10897) datasets as used in [Learning to Modulate Pre-trained Models in RL](https://arxiv.org/abs/2306.14884): 
-- Trajectories for every task are stored as separate `.npz` files. 
-- Every `.npz` file contains 2M transitions.
+- The `2M` folder contains trajectories (2M transitions) for every task are stored as separate `.npz`.
+- The `2M_separate` folder contains the same data, but every trajectory is stored as a separate `.hdf5` file and every task is stored as a `.tar.gz` file.
