I made my Environment (reset and step functions) but I want to use Genetic algorithm for NN tuning instead of gradient descent. How to do this?

Hello,

Evolutionary RL is not provided out of the box as of now. To use it you would have to implement a custom training loop (see here for an example).

I made custom training loop. I see that actorNetwork has several layers (including FullyConnected) but their Weights are [ ]. Where are weights of actorNetwork?

Please refer to this page on how to extract the weights of actors/critics.
