AttributeError: 'DataFrame' object has no attribute 'date'

date = self.data.date.unique()[0]

File "E:\Projects\FinRL-Meta\meta\env_stock_trading\env_stocktrading_China_A_shares.py", line 451, in _get_date
if len(self.df.tic.unique()) > 1:

AttributeError: 'DataFrame' object has no attribute 'date'
看调试数据， 只有这些列：
['tic', 'time', 'index', 'open', 'high', 'low', 'close', 'adjusted_close', 'volume', 'macd', 'boll_ub', 'boll_lb', 'rsi_30', 'cci_30', 'dx_30', 'close_30_sma', 'close_60_sma']

Seems time and date messed in files， there is commit to change column name from date to time, but not complete.
env_stocktrading_China_A_shares.py,
tushare.py

It's better to change it by author to make sure completeness and correctness, Thanks!
