FeaturesDict
episode_metadata FeaturesDict
episode_metadata/file_path Text string Path to the original data file.
episode_metadata/input_point_cloud Tensor (10000, 3) float16 Point cloud (geometry only) of the object at the beginning of the episode (world frame) as a numpy array (10000,3).
steps Dataset
steps/action Tensor (6,) float32 Robot action, consists of [end-effector velocity (v_x,v_y,v_z,omega_x,omega_y,omega_z) in world frame
steps/discount Scalar float32 Discount if provided, default to 1.
steps/is_first Tensor bool
steps/is_last Tensor bool
steps/is_terminal Tensor bool
steps/language_embedding Tensor (512,) float32 Kona language embedding. See https://tfhub.dev/google/universal-sentence-encoder-large/5
steps/language_instruction Text string Language Instruction.
steps/observation FeaturesDict
steps/observation/image Image (64, 64, 3) uint8 Main camera RGB observation. Not available for this dataset, will be set to np.zeros.
steps/observation/input_point_cloud Tensor (10000, 3) float16 Point cloud (geometry only) of the object at the beginning of the episode (world frame) as a numpy array (10000,3).
steps/observation/state Tensor (8,) float32 State, consists of [end-effector pose (x,y,z,yaw,pitch,roll) in world frame, 1x gripper open/close, 1x door opening angle].
steps/reward Scalar float32 Reward if provided, 1 on final step for demos.
