ARoboCarController

Controller for ARoboCar simulator

Setup notes

Please set OS environment variable called DATA_DIR to a directory where the controller will write the training and model hdf5 files. It needs to be fully qualified and not a relative path as h5py isn't able to deal with relative paths on Mac.

Running it on Windows

Install Unreal engine if you haven't.
Install Cygwin (Cygwin.com) - default installation worked for me. We need this for some code to work.
Install Visual Studio 2017 if you haven't. (This is the environment I tried with and you need it to rebuild the project)
Clone git repos - ARoboCar and ARoboCarController (you will need git) - https://github.com/eastbayML/
Open ARoboCar directory in file explorer, choose ARoboCar.uproject and open with a text editor. Under plugins, set UnrealEnginePython plugin to false. Now, select ARoboCar.uproject, click right mouse button and you should see the option to generate Visual Studio Project files.
Open the Visual studio solution file and build the solution. It also shows the path to python interactive environment. You should note that in case you have to install hdpy.
Install UnrealEnginePython from https://github.com/20tab/UnrealEnginePython/. Just place the directory under Plugins directory of your project.
Now open Epic Games, launch the Unreal Engine and open the project just to make sure you can. Re-enable UnrealEnginePython plugin and quit the engine.
Now go to a Cygwin terminal and set the required python environment e.g. "source activate root"
Open the project from commandline.
"$PATH_TO_ENGINE/UE4Editor.exe path_to_uproject_file_in_windows_convention"
Unreal engine doesn't seem to understand cygwin version of path so just use windows path
Next set your DATA_DIR environment variable, open your favorite python editor from commandline (in the cygwin environment). This is important for the communication to work between the two processes.
