Yahoo Downloader Not working

[Astroyimin]

Describe the bug
Yahoo Downloader is not working in Stock_NeurIPS2018_1_Data.ipynb.

I face the problem in that notebook. When i run

df_raw = YahooDownloader(start_date = TRAIN_START_DATE, end_date = TRADE_END_DATE, ticker_list = config_tickers.DOW_30_TICKER).fetch_data()

It's return error like ValueError: Length mismatch: Expected axis has 182 elements, new values have 8 elements. Then i check the yahoodownloader.py file, and add the df.shape at line 63 to print the information of dataframe after loop of stocks tick. The output is (94301, 182).

I don't know how to change that and i think it's due to the version of yfinance. Does anyone face the same error? Do you have some solution ?
