China_A_share_market_tushare AttributeError

[zhilee2023]

When I run China_A_share_market_tushare.ipynb, the following error came accross. It seems the dataframe has no attribute date.

I want to ask this question too, do you find the answer?

[zhilee2023]

I changed the codes to df['time'] or df['date']. It works for me.

just rename the col name works train = train.rename(columns={'time': 'date'})
