Dataset for the 1X World Model Challenge.

Current version: v1.1

• magvit2.ckpt - weights for MAGVIT2 image tokenizer we used. We provide the encoder (tokenizer) and decoder (de-tokenizer) weights.

Contents of train/val_v1.1:

• video.bin - 16x16 image patches at 30hz, each patch is vector-quantized into 2^18 possible integer values. These can be decoded into 256x256 RGB images using the provided magvig2.ckpt weights.
• segment_ids.bin - for each frame segment_ids[i] uniquely points to the segment index that frame i came from. You may want to use this to separate non-contiguous frames from different videos (transitions).
• actions/ - a folder of action arrays stored in np.float32 format. For frame i, the corresponding action is given by joint_pos[i], driving_command[i], neck_desired[i], and so on. The shapes and definitions of the arrays are as follows (N is the number of frames):
  • joint_pos (N, 21): Joint positions. See Index-to-Joint Mapping below.
  • driving_command (N, 2): Linear and angular velocities.
  • neck_desired (N, 1): Desired neck pitch.
  • l_hand_closure (N, 1): Left hand closure state (0 = open, 1 = closed).
  • r_hand_closure (N, 1): Right hand closure state (0 = open, 1 = closed).

We also provide a small val_v1.1 data split containing held-out examples not seen in the training set, in case you want to try evaluating your model on held-out frames.
