[](https://github.com/erdos-project/pylot/actions) [](https://pylot.readthedocs.io/en/latest/?badge=latest) Pylot is an autonomous vehicle platform for developing and testing autonomous vehicle components (e.g., perception, prediction, planning) on the CARLA simulator and real-world cars. * [**Setup instructions**](#setup-instructions) * [**Documentation**](https://pylot.readthedocs.io/en/latest/) * [**Pylot components**](#pylot-components) * [**Data collection**](#data-collection) * [**Build Docker image**](#build-your-own-docker-image) * [**CARLA autonomous driving challenge**](#carla-autonomous-driving-challenge) * [**Getting involved**](#getting-involved) # Setup instructions ## Deploy using Docker The easiest way to get Pylot running is to use our Docker image. Please ensure you have `nvidia-docker` on your machine before you start installing Pylot. In case you do not have `nvidia-docker` please run ```./scripts/install-nvidia-docker.sh``` We provide a Docker image with both Pylot and CARLA already setup. ```console docker pull erdosproject/pylot nvidia-docker run -itd --name pylot -p 20022:22 erdosproject/pylot /bin/bash ``` Following, start the simulator in the container: ```console nvidia-docker exec -i -t pylot /home/erdos/workspace/pylot/scripts/run_simulator.sh ``` Finally, start Pylot in the container: ```console nvidia-docker exec -i -t pylot /bin/bash cd ~/workspace/pylot/ python3 pylot.py --flagfile=configs/detection.conf ``` ## Visualizing components In case you desire to visualize outputs of different components (e.g., bounding boxes), you have to forward X from the container. First, add your public ssh key to the `~/.ssh/authorized_keys` in the container: ```console nvidia-docker cp ~/.ssh/id_rsa.pub pylot:/home/erdos/.ssh/authorized_keys nvidia-docker exec -i -t pylot sudo chown erdos /home/erdos/.ssh/authorized_keys nvidia-docker exec -i -t pylot sudo service ssh start ``` Finally, ssh into the container with X forwarding: ```console ssh -p 20022 -X erdos@localhost cd /home/erdos/workspace/pylot/ python3 pylot.py --flagfile=configs/detection.conf --visualize_detected_obstacles ``` If everything worked ok, you should be able to see a visualization like the one below:  ## Manual installation instructions Alternatively, you can install Pylot on your base system by executing the following steps: ```console ./install.sh pip install -e ./ ``` Next, start the simulator: ```console export CARLA_HOME=$PYLOT_HOME/dependencies/CARLA_0.9.10.1/ ./scripts/run_simulator.sh ``` In a different terminal, setup the paths: ```console export CARLA_HOME=$PYLOT_HOME/dependencies/CARLA_0.9.10.1/ cd $PYLOT_HOME/scripts/ source ./set_pythonpath.sh ``` Finally, run Pylot: ```console cd $PYLOT_HOME/ python3 pylot.py --flagfile=configs/detection.conf ``` # Pylot components Pylot comprises of several components: obstacle detection, traffic light detection, lane detection, obstacle tracking, localization, segmentation, fusion, prediction, planners, and control. Each component is implemented using one or more ERDOS operators and can be executed in isolation or with the entire Pylot application. Please read the [**Documentation**](https://pylot.readthedocs.io/en/latest/) for a more in depth description.  Run the following command to see a demo of all the components, and the Pylot driving policy: ```console python3 pylot.py --flagfile=configs/demo.conf ``` The demo will execute: obstacle detection, traffic light detection, segmentation, prediction, planning, and the driving policy. *** You can also run components in isolation: ### Obstacle detection Pylot supports three object detection models: `frcnn_resnet101`, `ssd-mobilenet-fpn-***0` and `ssdlite-mobilenet-v2`. The following command runs a detector in isolation: ```console python3 pylot.py --flagfile=configs/detection.conf ``` In case you want to evaluate the detector (i.e., compute mAP), you can run: ```console python3 pylot.py --flagfile=configs/detection.conf --evaluate_obstacle_detection ``` In case you are not satisfied with the accuracy of our obstacle detector, you can run a perfect version of it: ```console python3 pylot.py --flagfile=configs/perfect_detection.conf ``` If the detector does not run at your desired frequency, or if you want to track obstacles across frames, you can use a mix of detector plus tracker by running: ```console python3 pylot.py --flagfile=configs/tracking.conf ``` ### Traffic light detection Pylot has uses a separate component for traffic light detection and classification. The following command runs the component in isolation: ```console python3 pylot.py --flagfile=configs/traffic_light.conf ``` In case you require higher accuracy, you can run perfect traffic light detection by passing the ```--perfect_traffic_light_detection``` flag. ### Lane detection ```console python3 pylot.py --flagfile=configs/lane_detection.conf ``` ### Obstacle tracking ```console python3 pylot.py --flagfile=configs/tracking.conf ``` ### Segmentation In order to run Pylot's segmentation component in isolation execute the following command: ```console python3 pylot.py --flagfile=configs/segmentation.conf ``` Similarly, pass ```--perfect_segmentation``` if you desire ideal pixel semantic segmentation. ### Prediction Pylot offers a simple linear prediction component: ```console python3 pylot.py --flagfile=configs/prediction.conf ``` ### Planning The planning component provides two planning options, which can be specified using the ```--planning_type``` flag: 1. `waypoint`: a simple planner that follows predefined waypoints. These waypoints can either be either pre-specified or computed using the A-star planner part of the CARLA simulator map. The planner ensures that the ego-vehicle respects traffic lights, stops whenever there are obstacles in its path, but does not implement obstacle avoidance. 2. `frenet_optimal_trajectory`: a Frenet Optimal Trajectory planner. 3. `rrt_star`: a Rapidly-explory Random Tree planner. 4. `hybrid_astar`: a Hybrid A* planner. ```console # To run the Frenet Optimal Trajectory planner. python3 pylot.py --flagfile=configs/frenet_optimal_trajectory_planner.conf # To run the RRT* planner. python3 pylot.py --flagfile=configs/rrt_star_planner.conf # To run the Hybrid A* planner. python3 pylot.py --flagfile=configs/hybrid_astar_planner.conf ``` ### Control Pylot supports three controllers, which can be specified using the ```control``` flag: 1. `pid`: follows the waypoints computed by the planning component using a PID controller. 2. `mpc`: uses model predictive control for speed and waypoint following. 3. `simulator_auto_pilot`: uses the simulator auto pilot to drive on predefined routes. This controller drives independent of the output of the other components. You can run all the components, together with one of the two policies by executing: ```console # Runs all components using the algorithms we implemented and the models we trained: python3 pylot.py --flagfile=configs/e2e.conf # Runs the MPC python3 pylot.py --flagfile=configs/mpc.conf # Runs the simulator auto pilot. python3 pylot.py --control=simulator_auto_pilot ``` ### Debug logs In case you want to debug the application, you can active additional logging by passing: `--log_file_name=pylot.log --v=1` to your command. # Data collection Pylot also provides a script for collecting CARLA data such as: RGB images, segmented images, obstacle 2D bounding boxes, depth frames, point clouds, traffic lights, obstacle trajectories, and data in Chauffeur format. Run ```python3 data_gatherer.py --help``` to see what data you can collect. Alternatively, you can inspect this [configuration](https://github.com/erdos-project/pylot/blob/master/configs/data_gatherer.conf) for an example of a data collection setup. # Build your own Docker image In case you want to build your own images from the latest code, you can execute: ```console cd docker ./build_images.sh ``` The script creates two Docker images: one that contains the CARLA simulator and another one that contains ERDOS and Pylot. # CARLA autonomous driving challenge Pylot can also be used as a baseline for executing on the CARLA [**Leaderboard**](https://leaderboard.carla.org/) routes. We provide an agent that offers reference implementations for perception (i.e., detection, tracking), localization (Extended Kalman filter), prediction, planning (e.g., waypoint follower, Frenet optimal trajectory, RRT*, Hybrid A*), and control. To test this agent you can pull our image which has all the necessary software already installed. ```console docker pull erdosproject/pylot-carla-challenge nvidia-docker run -itd --name pylot-challenge -p 20022:22 erdosproject/pylot-carla-challenge /bin/bash ``` Alternatively, you can manually install the dependencies on your machine by following the instructions provided below: ```console mkdir challenge export CHALLENGE_ROOT=`pwd` # Clone the challenge leaderboard repository. git clone -b stable --single-branch https://github.com/carla-simulator/leaderboard.git export LEADERBOARD_ROOT=${CHALLENGE_ROOT}/leaderboard/ cd ${LEADERBOARD_ROOT} ; pip3 install -r requirements.txt ; cd ${CHALLENGE_ROOT} # Clone the CARLA scenario runner repository. This is used by the leaderboard. git clone -b leaderboard --single-branch https://github.com/carla-simulator/scenario_runner.git export SCENARIO_RUNNER_ROOT=${CHALLENGE_ROOT}/scenario_runner/ cd ${SCENARIO_RUNNER_ROOT} ; pip3 install -r requirements.txt ; cd ${CHALLENGE_ROOT} # Checkout the CARLA challenge branch. cd ${PYLOT_HOME} ; git checkout -b challenge origin/challenge export CARLA_ROOT=Path to CARLA 0.9.10.1. cd ${CHALLENGE_ROOT} export TEAM_CODE_ROOT=${PYLOT_HOME} ; ${LEADERBOARD_ROOT}/scripts/make_docker.sh ``` ## Notes on the Pylot CARLA challenge agent Similar to regular Pylot, the [Challenge agent](https://github.com/erdos-project/pylot/blob/master/pylot/simulation/challenge/ERDOSAgent.py) not only connects different reference implementation, but also provides the option of testing them in different configurations (e.g., test prediction, planning and control with perfect perception). This can be done by changing the flags in the [challenge configuration](https://github.com/erdos-project/pylot/blob/master/pylot/simulation/challenge/challenge.conf) according to the specification from the Pylot documentation. # More Information To read more about the ideas behind Pylot, refer to our paper, *Pylot: A Modular Platform for Exploring Latency-Accuracy Tradeoffs in Autonomous Vehicles* ([IEEE](https://ieeexplore.ieee.org/document/9561747/)) ([arXiv](https://arxiv.org/abs/2104.07830)).
