Webload method re-creates the model from scratch and should be called on the Algorithm without instantiating it first, e.g. model = DQN.load ("dqn_lunar", env=env) instead of model = DQN (env=env) followed by model.load ("dqn_lunar"). The latter will not work as load is not an in-place operation. WebSep 21, 2024 · In this article, we will try to understand Open-AI’s Proximal Policy Optimization algorithm for reinforcement learning. After some basic theory, we will be implementing PPO with TensorFlow 2.x. Before you read further, I would recommend you take a look at the Actor-Critic method from here, as we will be modifying the code of that …
