Index needs to be passed for training

When executing the following cell: df_summary = ensemble_agent.run_ensemble_strategy(A2C_model_kwargs, PPO_model_kwargs, DDPG_model_kwargs, timesteps_dict)

The following error is occurring: `--------------------------------------------------------------------------- ValueError Traceback (most recent call last) in <cell line: 1>() ----> 1 df_summary = ensemble_agent.run_ensemble_strategy(A2C_model_kwargs, 2 PPO_model_kwargs, 3 DDPG_model_kwargs, 4 timesteps_dict)

I'm also having the same issue
