I have followed each step as suggested by the readme. However, I encounter the problem as follow:

WARNING:tornado.general:Connect error on fd 336: WSAECONNREFUSED WARNING:tornado.general:Connect error on fd 336: WSAECONNREFUSED WARNING:tornado.general:Connect error on fd 336: WSAECONNREFUSED WARNING:tornado.general:Connect error on fd 336: WSAECONNREFUSED WARNING:tornado.general:Connect error on fd 336: WSAECONNREFUSED Traceback (most recent call last): File "policy_run.py", line 14, in env = DummyVecEnv([lambda: Monitor( File "E:\Anaconda\envs\PPO_drone\lib\site-packages\stable_baselines3\common\vec_env\dummy_vec_env.py", line 25, in init self.envs = [fn() for fn in env_fns] File "E:\Anaconda\envs\PPO_drone\lib\site-packages\stable_baselines3\common\vec_env\dummy_vec_env.py", line 25, in self.envs = [fn() for fn in env_fns] File "policy_run.py", line 15, in gym.make( File "E:\Anaconda\envs\PPO_drone\lib\site-packages\gym\envs\registration.py", line 235, in make return registry.make(id, kwargs) File "E:\Anaconda\envs\PPO_drone\lib\site-packages\gym\envs\registration.py", line 129, in make env = spec.make(kwargs) File "E:\Anaconda\envs\PPO_drone\lib\site-packages\gym\envs\registration.py", line 90, in make env = cls(**_kwargs) File "E:\Project\PPO_based_ANfQ\PPO-based-Autonomous-Navigation-for-Quadcopters\scripts\airsim_env.py", line 169, in init super(TestEnv, self).init(ip_address, image_shape, env_config) File "E:\Project\PPO_based_ANfQ\PPO-based-Autonomous-Navigation-for-Quadcopters\scripts\airsim_env.py", line 19, in init self.setup_flight() File "E:\Project\PPO_based_ANfQ\PPO-based-Autonomous-Navigation-for-Quadcopters\scripts\airsim_env.py", line 174, in setup_flight super(TestEnv, self).setup_flight() File "E:\Project\PPO_based_ANfQ\PPO-based-Autonomous-Navigation-for-Quadcopters\scripts\airsim_env.py", line 36, in setup_flight self.drone.reset() File "E:\Project\PPO_based_ANfQ\PPO-based-Autonomous-Navigation-for-Quadcopters\scripts\airsim\client.py", line 26, in reset self.client.call('reset') File "E:\Anaconda\envs\PPO_drone\lib\site-packages\msgpackrpc\session.py", line 41, in call return self.send_request(method, args).get() File "E:\Anaconda\envs\PPO_drone\lib\site-packages\msgpackrpc\future.py", line 43, in get raise self._error msgpackrpc.error.TransportError: Retry connection over the limit

I would be grateful if anyone could tell me how to fix this.

Hi,

It seems like the Unreal environment was not opened up. Prior to running the script, you should download the environment from releases and extract it. Then, open up the .exe file in that folder. This will open up an Unreal environment. Finally, you can run the script.
