I suppose this due to update in elegantrl-0.3.3.

The implementation of the initialization doesn't seem to finished yet for elegantrl. There are multiple issues still.

1. There is further selection layer needed for concrete implementation of the agents. MODELS = {"ddpg": AgentDDPG.AgentDDPG(), "td3": AgentTD3.AgentTD3(), "sac": AgentSAC.AgentSAC(), "ppo": AgentPPO.AgentPPO()} in finrl.agents.elegantrl..models.py -temporary fix
2. Argument class has no argument agent_class, it has to be changed to agent and will only accept an object with members init, explore_env, ...
3. The gpu_id is not initialized properly
