Hi sir, I'm getting this error when running the main.py.

Traceback (most recent call last):

    raise error.RPCError(self._error)
msgpackrpc.error.RPCError: rpclib: function 'enableApiControl' (called with 2 arg(s)) threw an exception. The exception contained this information: Vehicle API for 'drone0' is not available. This could either because this is simulation-only API or this vehicle does not exist.

Hoping u can help me out with this.

Hello, Can you please share the content of your config.cfg file?

Hi, I was getting the same error since my Documents folder is inside my OneDrive folder. In main.py, it looks for setting.json in C:\Users\user_name\Documents\Airsim\settings.json directory.

path = os.path.expanduser('~\Documents\Airsim')

So, I changed the above line in main.py like this

path = os.path.expanduser('~\OneDrive\Documents\Airsim')

Now, it is working.

Hi, I was getting the same error since my Documents folder is inside my OneDrive folder. In main.py, it looks for setting.json in C:\Users\user_name\Documents\Airsim\settings.json directory.

path = os.path.expanduser('~\Documents\Airsim')

So, I changed the above line in main.py like this

path = os.path.expanduser('~\OneDrive\Documents\Airsim')

Now, it is working.

hi, it seems like my path setting is correct. still got the same error info

I recommend you to locate the settings.json file which is by default inside Documents\AirSim directory. Normally, after running the main.py, it should look like this

{
    "SettingsVersion": 1.2,
    "LocalHostIp": "127.0.0.5",
    "SimMode": "Multirotor",
    "ClockSpeed": 20,
    "ViewMode": "FlyWithMe",
    "PawnPaths": {
        "DefaultQuadrotor": {
            "PawnBP": " Class'/AirSim/Blueprints/BP_DJIMavic.BP_DJIMavic_C' "
        }
    },
    "Vehicles": {
        "drone0": {
            "VehicleType": "SimpleFlight",
            "X": 0.0,
            "Y": 0.0,
            "Z": 0,
            "Yaw": 0.0
        }
    },
    "CameraDefaults": {
        "CaptureSettings": [
            {
                "ImageType": 0,
                "Width": 320,
                "Height": 180,
                "FOV_Degrees": 80
            },
            {
                "ImageType": 3,
                "Width": 320,
                "Height": 180,
                "FOV_Degrees": 80
            }
        ]
    }
}

If it is not like this for your case, you can copy above lines and paste them into your settings.json file and try again. This may help.

Thank you for your help! I copied your 'settings.json' into mine and ran the main.py. However, after function 'enableApiControl' (called with 2 arg(s)) threw an exception, the file has been rewrite to this automatically: { "SeeDocsAt": "https://github.com/Microsoft/AirSim/blob/master/docs/settings.md", "SettingsVersion": 1.2 } or else the other kind of error is msgpackrpc.error.TimeoutError: Request timed out I checked out the generation_json(cfg) function in main.py separately, it worked just fine. Then I tried to delete the parameter 'name_agent' in enableApiControl function as the error info told me... After removed many 'name_agent' parameter in the whole project, it seemed to run the algorithm without exception thrown... But I doubt that it can be debug this way...because the settings.json still isn't correct.

Hi, I found that the error occurred due to my asian characters in settings.json file path. My user name is asian character, which may not supported by AirSim. After changing that, simulation began in the end.
