Error in Demo_MultiCrypto_Trading.ipynb

I opened the file in Google Collab thinking that it should be straightforward to run once the libraries are installed. All libraries got installed but when I run the train method below, I get the error of _TypeError: __init__() missing 3 required positional arguments: 'start_date', 'end_date', and 'time_interval'_

train(start_date=TRAIN_START_DATE,
end_date=TRAIN_END_DATE,
