Sensor2Sensor — precomputed training caches (nuScenes, 850 scenes)

Precomputed frozen-encoder outputs for training the DINOv3-conditioned LiDAR diffusion model in github.com/skr3178/sensor2sensor without downloading the 57 GB raw nuScenes dataset.

Model weights: huggingface.co/sangramrout/sensor2sensor.

Contents

Two matched caches — 34,149 CAM_FRONT + LIDAR_TOP keyframes (all 850 nuScenes v1.0-trainval scenes), joined by the sample_token filename. Each is a tarball of per-token .npz files.

cached_latents_v5_850scenes.tar (3.3 GB)

key shape / dtype role
mu [8,8,256] f32 diffusion target — v5 LiDAR-VAE latent
raymap [6,32,56] f32 conditioning — ray directions
image_latent [4,32,56] f32 legacy SD-1.5 image cond (unused by the DINOv3 model)
sample_token scalar str nuScenes sample token

cached_dinov3_v5_850scenes.tar (7.7 GB)

key shape / dtype role
feat [384,14,24] f16 image conditioning — DINOv3 features (upsampled → 32×56 at train time)
sample_token scalar str nuScenes sample token

You need both: feat + raymap (conditioning) → predict mu (target). The DINOv3 cache has no target; the latents cache has no DINOv3 conditioning.

Provenance (frozen encoders)

  • Image latent (image_latent): SD-1.5 VAE
  • LiDAR latent (mu): v5 LiDAR VAE @ step 3933 (lidar_vae_best.pt, on the model repo)
  • DINOv3 (feat): vit_small_patch16_dinov3.lvd1689m, input 224×384

Built with s2s_min/train/cache_latents.py and s2s_min/train/cache_dinov3.py in the GitHub repo. Subset: np.random.default_rng(0).choice(850, 850, replace=False).

Usage

hf download sangramrout/sensor2sensor-cache --repo-type dataset --local-dir ./cache
tar xf ./cache/cached_latents_v5_850scenes.tar -C s2s_min/out/
tar xf ./cache/cached_dinov3_v5_850scenes.tar -C s2s_min/out/
# then train per the GitHub README
