Ошибка синтаксического анализа при загрузке данных CSV в Zipline с помощью CSVDIR

Я загружаю CSV-файлы, используя пакет CSVDIR в Zipline.Выдает ошибку «ValueError: Ошибка синтаксического анализа строки времени и даты« A.csv »в позиции 0».Как это можно решить?

Когда я загружаю его напрямую с помощью панд, он загружается нормально: 

>>> Acsv = pd.read_csv("D:/work/tmp/hData/bundles/data/NYSE_dat/A.csv", parse_dates=[0], infer_datetime_format=True, index_col=0)
>>> Acsv.head()
             open   high    low  close   volume  dividend  split
date

Вот код ошибки с кодом:
