• CVPR 2024 Autonomous Driving Challenge - Driving with Language

🔥 The first embodied language model for understanding the long-horizon driving scenarios in space and time.

🌟 ELM expands a wide spectrum of new tasks to fully leverage the capability of large language models in an embodiment setting and achieves significant improvements in various applications.

🏆 Interpretable driving model, on the basis of language prompting, will be a main track in the CVPR 2024 Autonomous Driving Challenge. Please stay tuned for further details!

• 🔥 Interpretable driving model is launched. Please refer to the link for more details.
• [2024/03] ELM paper released.
• [2024/03] ELM code and data initially released.

1. (Optional) Creating conda environment

conda create -n elm python=3.8
conda activate elm

2. install from PyPI

pip install salesforce-lavis

3. Or, for development, you may build from source

git clone https://github.com/OpenDriveLab/ELM.git
cd ELM
pip install -e .

Pre-training data. We collect driving videos from YouTube, nuScenes, Waymo, and Ego4D. Here we provide a sample of 🔗 YouTube video list we used. For privacy considerations, we are temporarily keeping the full-set data labels private. Part of pre-training data and reference checkpoints can be found in 💾 google drive.

Fine-tuning data. The full set of question and answer pairs for the benchmark can be obtained through this 🔗data link. You may need to download the corresponding image data from the official nuScenes and Ego4D channels. For a quick verification of the pipeline, we recommend downloading the subset dataset of DriveLM and organizing the data in line with the format.

Please make sure to soft link nuScenes and ego4d datasets under data/xx folder. You may need to run tools/video_clip_processor.py to pre-process data first. Besides, we provide some script used during auto-labeling, you may use these as a reference if you want to customize data.

# you can modify the lavis/projects/blip2/train/advqa_t5_elm.yaml
bash scripts/train.sh

Modify the advqa_t5_elm.yaml to enable the evaluate as True.

bash scripts/train.sh

For the evaluation of generated answers, please use the script in scripts/qa_eval.py.

python scripts/qa_eval.py <data_root> <log_name>
