# **Reinforce** Agent playing **LunarLanderContinuous-v2**
This is a custom agent. Performance has been measured over 900 episodes.
To try the agent, user needs to import the ParameterisedPolicy class from the Agent_class.py file. </br>
Training progress:
![training](training_graph.jpg)
Numbers on X axis are average over 40 episodes, each lasting for about 500 timesteps on average. So in total the agent was trained over about 5e6 timesteps.
Learning rate decay schedule: <code>torch.optim.lr_scheduler.StepLR(opt, step_size=4000, gamma=0.7)</code>
Minimal code to use the agent:</br>
```
import gym
from agent_class import ParameterisedPolicy
env_name = 'LunarLanderContinuous-v2'
env = gym.make(env_name)
agent = torch.load('best_reinforce_lunar_lander_cont_model_269.402.pt')
render = True
observation = env.reset()
while True:
if render:
env.render()
action = agent.act(observation)
observation, reward, done, info = env.step(action)
if done:
break
env.close()
