FinRL Error encountered when running practical tutorial

Hi,

I was trying to run the following tutorial notebook, but the following error was encountered:

---------------------------------------------------------------------------

AttributeError: 'Timedelta' object has no attribute 'delta'

Is there something wrong with the data query?

Same issue running on colab. Running on local jupyter notebook just gives warning:

data = DP.download_data(start_date = '2021-10-04', end_date = '2021-10-08', ticker_list = ticker_list, time_interval= '1Min')
