Run multiple simulations at a time

[ghost]

I want to run multiple simulations at a time, so I used different local host IPs to do it. I added the following to my AirSim's settings.json file: "LocalHostIp": "127.0.0.x" Then, I passed this same IP to AirSim Multirotor client in python: client = airsim.MultirotorClient(ip="127.0.0.x") The connection was successful but I got error when starting the race:

Code:

>>> import airsimneurips
>>> client = airsimneurips.MultirotorClient(ip="127.0.0.5")
>>> client.simLoadLevel('Qualifier_Tier_1')
True
>>> client.confirmConnection()
Connected!
>>> client.enableApiControl(vehicle_name='drone_1')
>>> client.arm(vehicle_name='drone_1')
True
>>> client.simStartRace(1)

I seems that the problem is only with simStartRace. When I use normal AirSim commands there is no problem, for example: "moveToPositionAsync".
