Yahoo Downloader not working

[tanobugelli]

I've been using FINRL for a while and had no issues downloading data from Yahoo before. For some reason I'm getting this error whenever I try to download anything. Is this something from their end?

I faced the same issue, and found a solution

1. upgrade your yfinance package
2. you will find how to change in yahoodownloader.py file. You just need to add auto_adjust=False for yf.download, because YF.download() has changed argument auto_adjust default to True

Sorted! Thanks @HerronYang

I faced one more issue , in.

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

Its return ValueError: Length mismatch: Expected axis has 182 elements, new values have 8 elements.

I check the yahoodownloader.py file, i think the loop for ticker_list return error dataframe format. I add the df.shape to print the information after loop. Its return (94301, 182)
