TypeError in run_ensemble_strategy method due to missing arguments

I followed the instructions from [this tutorial/notebook](https://github.com/AI4Finance-Foundation/FinRL-Tutorials/blob/master/2-Advance/FinRL_Ensemble_StockTrading_ICAIF_2020.ipynb) and expected the method to work as shown.

`df_summary = ensemble_agent.run_ensemble_strategy(A2C_model_kwargs,
PPO_model_kwargs,
DDPG_model_kwargs,
timesteps_dict)`

**And the code above was working before, but now it keeps throwing back the error below.**
