About Carla Apollo Bridge

Carla Apollo Bridge aims to provide a data and control bridge for the communication between the latest version of Carla and Apollo. It was tested with Carla 0.9.13 and Apollo master branch (newer than v7.0.0)

Getting Started

Prerequisites

We will run Carla and Apollo in docker. Furthermore, NVIDIA Container Toolkit is needed. You can refer to the following link to install NVIDIA Container Toolkit:

• https://docs.nvidia.com/datacenter/cloud-native/container-toolkit/install-guide.html

Alternatively, simply perform the following steps：

• docker

  sudo apt-get install docker.io

• NVIDIA Container Toolkit

  curl https://get.docker.com | sh \
  && sudo systemctl --now enable docker

  distribution=$(. /etc/os-release;echo $ID$VERSION_ID) \
      && curl -fsSL https://nvidia.github.io/libnvidia-container/gpgkey | sudo gpg --dearmor -o /usr/share/keyrings/nvidia-container-toolkit-keyring.gpg \
      && curl -s -L https://nvidia.github.io/libnvidia-container/$distribution/libnvidia-container.list | \
            sed 's#deb https://#deb [signed-by=/usr/share/keyrings/nvidia-container-toolkit-keyring.gpg] https://#g' | \
            sudo tee /etc/apt/sources.list.d/nvidia-container-toolkit.list

  sudo apt-get update

  sudo apt-get install -y nvidia-docker2

  sudo systemctl restart docker

Build And Run Apollo

• Refer to this link：
  https://github.com/ApolloAuto/apollo/blob/master/docs/quickstart/apollo_software_installation_guide.md

1. Clone the Apollo repo, please use guardstrike/apollo_carla_bridge branch

   # Using SSH
   git clone --branch guardstrike/apollo_carla_bridge [email protected]:guardstrikelab/apollo.git
   
   #Using HTTPS
   git clone --branch guardstrike/apollo_carla_bridge https://github.com/guardstrikelab/apollo.git

2. Build Apollo

   cd apollo
   echo "export APOLLO_ROOT_DIR=$(pwd)" >> ~/.bashrc  && source ~/.bashrc

   Then, run:

   bash docker/scripts/dev_start.sh

   to start Apollo development Docker container.
   If you encountered an error, try:

   sudo rm -rf /apollo/.cache
   bash docker/scripts/dev_start.sh

   After the execution is successful, there will be the following output

   [ OK ] Congratulations! You have successfully finished setting up Apollo Dev Environment.
   [ OK ] To login into the newly created apollo_dev_lei container, please run the following command:
   [ OK ]   bash docker/scripts/dev_into.sh
   [ OK ] Enjoy!

   Run the command and enter the container:

   bash docker/scripts/dev_into.sh

   Make the GPU version:

   ./apollo.sh build_gpu

   After successful compilation, the following will be printed:

   ==============================================
   [ OK ] Done building apollo. Enjoy!
   ==============================================

   Run the command in the container:

   ./scripts/bootstrap.sh

   Finnaly, open the link in your browser:

Run Carla

• Clone apollo_carla_bridge project:

  # Using SSH
  git clone [email protected]:guardstrikelab/apollo_carla_bridge.git
  
  #Using HTTPS
  git clone https://github.com/guardstrikelab/apollo_carla_bridge.git

• Install docker-compose

  sudo apt-get install docker-compose

• Pull carla image and run

  cd apollo_carla_bridge/scripts
  ./docker_run_carla.sh

Run apollo_carla_bridge

1. Run and enter docker

   cd apollo_carla_bridge/docker
   ./build_docker.sh
   ./run_docker.sh
   docker exec -ti carla_cyber_0.9.13 bash

2. Compile

   Run the following command in the container:

   ./apollo.sh build_cyber opt

   The following information is displayed after the compilation is successful:

   [INFO] Skipping revision recording
   ============================
   [ OK ] Build passed!
   [INFO] Took 61 seconds

3. Run

   Run the following command in the container.

   cd /apollo/cyber/carla_bridge
   python carla_cyber_bridge/bridge.py

   Start a new terminal and run:

   docker exec -ti carla_cyber_0.9.13 bash
   cd /apollo/cyber/carla_bridge
   python carla_spawn_objects/carla_spawn_objects.py
