Was trying to download a string of tickers when i ran into this problem. pip install -U yfinance pandas fixed it.

Answer 2

After upgrading to yfinance version 0.1.70, the problem has gone. My version of pandas is 1.4.1. use pip install -U yfinance pandas to update.

For reference, my version of yfinance was 0.1.63 and pandas was 1.4.1.
