[Please Help]AssertionError: The observation space must be an image or dictionary observation space

[skgr07]

I cannot run the RL examples in Airsim because of this error.
Is there anyone who had solved or who can help me with this error?
I've googling on this issue for a week, but i can't find the solution.
