cycarla-backend 0.1.5

Backend for Cycarla

cycarla-backend is a Python Flask server that serves as the backend to CYCARLA

The three components of Cycarla are:

1. CARLA - An open-source simulator for autonomous driving research.
2. cycarla_backend - This Python Flask server which links the frontend to CARLA.
3. cycarla_frontend - A Javascript (Next.js) front-end which presents a web-based interface from your browser.

Installation

Supported platforms: Windows 10, Ubuntu 22.04. Other versions can work if you install Python 3.10 and pipx.

Windows 10-specific Prerequisites

If you are on Ubuntu 22.04, skip ahead to the next section. Windows needs a couple of things to be set up beforehand.

1. Install Python 3.10

Scroll to the bottom and download the 'Windows Installer (64-bit)'.

At the installer, make sure to enable the bottom option "Add python.exe to PATH"

2. Install Scoop

Install using pipx

cycarla-backend is a CLI package that is developed with poetry and published on pypi.

We'll use pipx to run it in an isolated python environment.

Install pipx

Follow relevant instructions for your platform

Install cycarla-backend using pipx

pipx install cycarla-backend

Note the dash (minus) sign.

Run App

In your terminal (Ubuntu) or Powershell (Windows):

cycarla_backend

Note the underscore.

On Windows, Allow firewall permissions when prompted.r Cycoutput including:

 * Running on http://127.0.0.1:9000

This app will receive web requests from the CYCARLA Frontend which should run at localhost port 3000, and communicate with the Python API of a local CARLA simulator whose default port is 2000.

You should start the CARLA and frontend applications next, if they haven't been started already.

See CYCARLA top-level project README for more information

Compatibility

• Currently, Windows 10 and Ubuntu 22.04 are the officially supported OSes for the CYCARLA project. Mac is not supported because CARLA can't run on it.
• It is possible to run CARLA and this backend on two different computers, but it is very slow (~5 FPS).
