msgpackrpc.error.RPCError: rpclib: server could not find function 'simStartRace' with argument count 1. about airsim-neurips2019-drone-racing

@hany606 that API is released with the latest environment binary. If you are using an older release, simStartRace, simResetRace, simGetObjectScale, and simSetObjectScale, will not be available. You can find the latest linux release here.

Make sure you have the right settings configuration by running generate_settings_file.py. Your errors are because baseline_racer expects a specific configuration for the simulation.

@msb336 Yeah it works with the newest release, I didn't see the new release, thank you.
But when I run it, it was weird to get some errors like that:

msgpackrpc.error.RPCError: rpclib: function 'enableApiControl' (called with 2 arg(s)) threw an exception. The exception contained this information: Vehicle API for 'drone_1' is not available. This could either because this is simulation-only API or this vehicle does not exist.

then I removed the argument vehicle_name=self.drone_name from all the functions and it worked.

And also got

msgpackrpc.error.RPCError: rpclib: function 'simGetImages' (called with 2 arg(s)) threw an exception. The exception contained this information: invalid map<K, T> key.

and it is solved by exchange "fpv_cam" argument with 0 in request = [airsim.ImageRequest("fpv_cam", airsim.ImageType.Scene, False, False)] and it worked without any errors.

Everything work now, thank you.

Note: My setup is: the API is running on Linux and the simulator on different machine on windows.
