Dataset for the [1X World Model Challenge](https://github.com/1x-technologies/1xgpt).
Download with:
```
huggingface-cli download 1x-technologies/worldmodel --repo-type dataset --local-dir data
```
Changes from v1.1:
- New train and val dataset of 100 hours, replacing the v1.1 datasets
- Blur applied to faces
- Shared a new raw video dataset under CC-BY-NC-SA 4.0: https://huggingface.co./datasets/1x-technologies/worldmodel_raw_data
Contents of train/val_v2.0:
The training dataset is shareded into 100 independent shards. The definitions are as follows:
- **video_{shard}.bin**: 8x8x8 image patches at 30hz, with 17 frame temporal window, encoded using [NVIDIA Cosmos Tokenizer](https://github.com/NVIDIA/Cosmos-Tokenizer) "Cosmos-Tokenizer-DV8x8x8".
- **segment_idx_{shard}.bin** - Maps each frame `i` to its corresponding segment index. You may want to use this to separate non-contiguous frames from different videos (transitions).
- **states_{shard}.bin** - States arrays (defined below in `Index-to-State Mapping`) stored in `np.float32` format. For frame `i`, the corresponding state is represented by `states_{shard}[i]`.
- **metadata** - The `metadata.json` file provides high-level information about the entire dataset, while `metadata_{shard}.json` files contain specific details for each shard.

Previous version: v1.1
- **magvit2.ckpt** - weights for [MAGVIT2](https://github.com/TencentARC/Open-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.
