OpenEMMA: Open-Source Multimodal Model for End-to-End Autonomous Driving

OpenEMMA is an open-source implementation of Waymo's End-to-End Multimodal Model for Autonomous Driving (EMMA), offering an end-to-end framework for motion planning in autonomous vehicles. OpenEMMA leverages the pretrained world knowledge of Vision Language Models (VLMs), such as GPT-4 and LLaVA, to integrate text and front-view camera inputs, enabling precise predictions of future ego waypoints and providing decision rationales. Our goal is to provide accessible tools for researchers and developers to advance autonomous driving research and applications.

Installation

To get started with OpenEMMA, follow these steps to set up your environment and dependencies.

1. Environment Setup
   Set up a Conda environment for OpenEMMA with Python 3.8:

   conda create -n openemma python=3.8
   conda activate openemma
   

2. Install OpenEMMA
   You can now install OpenEMMA with a single command using PyPI:

   pip install openemma
   

   Alternatively, follow these steps:

   • Clone OpenEMMA Repository
     Clone the OpenEMMA repository and navigate to the root directory:

     git clone git@github.com:taco-group/OpenEMMA.git
     cd OpenEMMA
     

   • Install Dependencies
     Ensure you have cudatoolkit installed. If not, use the following command:

     conda install nvidia/label/cuda-12.4.0::cuda-toolkit
     

     To install the core packages required for OpenEMMA, run the following command:

     pip install -r requirements.txt
     

     This will install all dependencies, including those for YOLO-3D, an external tool used for critical object detection. The weights needed to run YOLO-3D will be automatically downloaded during the first execution.

3. Set up GPT-4 API Access
   To enable GPT-4’s reasoning capabilities, obtain an API key from OpenAI. You can add your API key directly in the code where prompted or set it up as an environment variable:

   export OPENAI_API_KEY="your_openai_api_key"
   

   This allows OpenEMMA to access GPT-4 for generating future waypoints and decision rationales.

Usage

After setting up the environment, you can start using OpenEMMA with the following instructions:

1. Prepare Input Data
   Download and extract the nuScenes dataset

2. Run OpenEMMA
   Use the following command to execute OpenEMMA's main script:

   • PyPI:

   openemma \
       --model-path qwen \
       --dataroot [dir-of-nuScenes-dataset] \
       --version [version-of-nuScenes-dataset] \
       --method openemma
   

   • Github Repo:

   python main.py \
       --model-path qwen \
       --dataroot [dir-of-nuscnse-dataset] \
       --version [version-of-nuscnse-dataset] \
       --method openemma
   

   Currently, we support the following models: GPT-4o, LLaVA-1.6-Mistral-7B, Llama-3.2-11B-Vision-Instruct, and Qwen2-VL-7B-Instruct. To use a specific model, simply pass gpt, llava, llama, and qwenas the argument to --model-path.

3. Output Interpretation
   After running the model, OpenEMMA generates the following output in the ./qwen-results location:

   • Waypoints: A list of future waypoints predicting the ego vehicle’s trajectory.

   • Decision Rationales: Text explanations of the model’s reasoning, including scene context, critical objects, and behavior decisions.

   • Annotated Images: Visualizations of the planned trajectory and detected critical objects overlaid on the original images.

   • Compiled Video: A video (e.g., output_video.mp4) created from the annotated images, showing the predicted path over time.
