CARLA is a very performance demanding software, at the very minimum you would
|

need a computer with a dedicated GPU capable of running Unreal Engine. See

[Unreal Engine's recommended hardware](https://wiki.unrealengine.com/Recommended_Hardware).

However, you will also need to build and install Unreal Engine, which on Linux
|

requires much more disk space as it keeps all the intermediate files,

Yes, you can connect a Python client to a simulator running within Unreal

Editor. Press the "Play" button and wait until the scene is loaded, at that
|

point you can connect as you would with the standalone simulator.

In Linux, the recommended way is to run `make package` in the project folder.

This method makes a packaged version of the project, including the Python API

|

|

Alternatively, it is possible to compile a binary version of CARLA within Unreal
|
||||
Editor, open the CarlaUE4 project, go to the menu "File -> Package Project", and
|
||||
select your platform. This takes a while, but in the end it should generate a
|
||||
packaged version of CARLA to execute without Unreal Editor.
