Chapter 8 - run_algorithm() got an unexpected keyword argument 'custom_loader' in backtest with zipline

Hi,
During running ./08_ml4t_workflow/04_ml4t_workflow_with_zipline/02_backtesting_with_zipline.ipynb
I got the error below:
TypeError: run_algorithm() got an unexpected keyword argument ‘custom_loader’

How can I add custom loader in run_algorithm? Should I modify run_algorithm and how?

Thanks,
