Research direction
This issue asks how to export a RecurrentPPO model to ONNX format. The contributor should explore the existing ONNX export utilities in the stable baselines3 codebase (e.g., in sb3.common.onnx or similar) and test if they work with recurrent policies. If not, they may need to extend the export function to handle the recurrent state or propose a fix. Finally, they should update the documentation with a step by step guide.
