Hello,
The error you're encountering is due to a mismatch between the observation names used in your environment's observation specification ‘stateSpec.Name’ and the names of the input layers in your deep neural network. The names must match exactly.
Here’s how you can resolve this issue:
- Ensure that the ‘Name’ property of the ‘featureInputLayer’ in your actor and critic networks matches the Name property of ‘stateSpec’.
- Verify that the ‘stateSpec.Name’ is correctly defined and matches the names used in your neural network.
- Try adding a check to ensure that ‘stateName’ is a string. If ‘stateName’ is a cell array, it extracts the first element. This should ensure that the ‘Name’ property of the ‘featureInputLayer’ matches the Name property of ‘stateSpec’.
% Ensure stateName is a string
if iscell(stateName)
stateName = stateName{1};
end
Although, ‘rlDeterministicActorRepresentation’ is not recommended anymore since R2022a, you can use ‘rlContinuousDeterministicActor’ instead.

Hope it helps!
