I noticed that this repo hasn't been updated since June 2023, I am getting an error with DataFrame append, this is the code:
from finquant.portfolio import build_portfolio names = ['GOOG', 'AMZN'] start_date = '2020-01-01' end_date = '2021-12-31' pf = build_portfolio(names=names, start_date=start_date, end_date=end_date, data_api='yfinance')
And this is the error I am getting:
