Think Twice before Driving: Towards Scalable Decoders for End-to-End Autonomous Driving

• A SOTA Decoder for End-to-End Autonomous Driving under BEV
• arXiv Paper (CVPR 2023)

Demo Video

Getting Started

• Installation
• Closed-Loop Evaluation in Carla
• Prepare Dataset
• Train Your Own Model
• Calibrations for Different Camera Settings (Optional)

Quick Run in Carla

Install the environment as in Installation, download our checkpoint (GoogleDrive or BaiduYun(提取码 m5di).) (189K frames training set), put it into open_loop_training/ckpt, and run:

## In the ThinkTwice/ directory
CUDA_VISIBLE_DEVICES=0  nohup bash ./leaderboard/scripts/evaluation_town05long.sh 22023 22033 thinktwice_agent  False True open_loop_training/ckpt/thinktwice.pth+open_loop_training/configs/thinktwice.py all_towns_traffic_scenarios_no256 thinktwice_town05long 2>&1 > thinktwice_town05long.log &

Check closed_loop_eval_log/eval_log to see how our model drives in Carla! 🚘

(In case you have a screen to see the interface of Carla simulator, you could remove DISPLAY= in leaderboard/leaderboard/leaderboard_evaluator.py and then you could directly watch with Carla.)

Code Structure

We give the structure of our code. Note that we only introduce those folders/files are commonly used and modified.
