Yfinance suddenly raises SSLError

Question

I have code that suddenly started raising errors while running it. Some time ago worked fine and still works on the PC i was using ~6 months ago (for the same code).

Tracked the problem to yfinance package that raises the error with just:

import yfinance as yf

#Test code w. Apple as ticker

tickerData = yf.Ticker('AAPL')

tickerData.info

The error I am getting is:::

Any idea how to fix (and any idea why the sudden change?) Thanks A

Answer 1

For me it is working, I think it might be the issue with the version . Please install the latest version by

pip install finance

Then your code will work

import yfinance as yf
tickerData = yf.Ticker('AAPL')
print(tickerData.info)
