Environment Setup

[!IMPORTANT] We recommend Ubuntu >= 22.04 + Python >= 3.10 + CUDA >= 12.3. You can create a mamba (or conda) environment before proceeding.

1. Install ROS2 Humble on your machine
2. Clone this repo and cd to the folder

    git clone git@github.com:LeCAR-Lab/anycar.git
    cd anycar
3. Create a new mamba environment and activate it

    
```bash
    mamba create -n anycar python=3.10
    mamba activate anycar
    

1. Install python dependencies

    pip install -r requirements.txt
    

1. Add the path of this project folder to your environment path CAR_PATH

    export CAR_PATH=$(pwd)
    

1. Add Python Path and Interpreter for ROS2 Compatibility

   • get python path: which python
   • get python path to packages: python -c "import site; print(site.getsitepackages()[0])"

    export PYTHON_EXECUTABLE=PATH-OF-PYTHON
    export PYTHONPATH=PATH-OF-PYTHON-SITE-PACKAGES:$PYTHONPATH
    

1. Build the project

    colcon build
    

1. Source the environment

    source install/setup.bash 
    

1. Download Foxglove Studio and import the visualization config from misc/anycar-vis.json

Quick Start

1. run foxglove node:

ros2 launch foxglove_bridge foxglove_bridge_launch.xml

1. run car_sim node:

XLA_PYTHON_CLIENT_MEM_FRACTION=0.3 ros2 launch car_ros2 car_sim.launch.py

1. Check the visualization in Foxglove Studio localhost:8765
