1
Install Stable Baselines3
Run `pip install stable-baselines3` to install the library.
2
Create or Load Environment
Create a Gymnasium environment or load an existing one; VecEnv is used internally for vectorized environments.
3
Initialize Model
Initialize a model, for example: `model = PPO("MlpPolicy", env, verbose=1)`.
4
Train the Model
Train the model using `model.learn(total_timesteps=10000)`.
5
Save and Load Model
Save the trained model with `model.save("path")` and load it later using `model = PPO.load("path")`.
