# AutoMoT PDM-Lite TransFuser Indexes

This dataset repo stores the public JSONL indexes used by the AutoMoT PDM-Lite fast-reasoning training path.

The files are distributed as `.jsonl.zst` to keep downloads small. Decompress them into `PDM_JSONL_DIR` before training.

This repo does not include the full PDM-Lite sensor data or TransFuser++ feature tensors. Each JSONL row points to a precomputed TransFuser++ feature file via `transfuser_feature` and frame id via `transfuser_feature_frame`.

## Files

- `pdm_lite_2hz_2tp_train_transfuser.jsonl.zst`
- `pdm_lite_2hz_2tp_val_transfuser.jsonl.zst`

After decompression, AutoMoT expects:

- `pdm_lite_2hz_2tp_train_transfuser.jsonl`
- `pdm_lite_2hz_2tp_val_transfuser.jsonl`

## Expected Row Fields

Each row keeps the conversation/training metadata and includes:

- `transfuser_feature`: relative path to `transfuser_feature/route_features.pt`
- `transfuser_feature_frame`: frame id inside the route feature file

The prompt uses `<trans>` for the TransFuser++ BEV feature token. Front camera images are not fed directly into MoT in this training path.

## Download

```bash
huggingface-cli download HqH1111/AutoMoT-PDM-Lite-TransFuser-Indexes   pdm_lite_2hz_2tp_train_transfuser.jsonl.zst   pdm_lite_2hz_2tp_val_transfuser.jsonl.zst   --repo-type dataset   --local-dir "$PDM_JSONL_DIR"

unzstd -f "$PDM_JSONL_DIR/pdm_lite_2hz_2tp_train_transfuser.jsonl.zst"
unzstd -f "$PDM_JSONL_DIR/pdm_lite_2hz_2tp_val_transfuser.jsonl.zst"
```

## Use With AutoMoT

```bash
cd Automot
source configs/env.sh
CUDA_VISIBLE_DEVICES=0 TOTAL_STEPS=1 DO_EVAL=False NUM_WORKERS=0   bash scripts/train/train_pdm_lite_reasoning.sh
```

The training loader expects the PDM-Lite data root and precomputed TransFuser++ features to be available locally through `PDM_DATA_DIR`.
