TypeError: float() argument must be a string or a number, not 'DataFrame'

[emanuellabat]

When I run a test code:

from empyrial import empyrial, Engine

portfolio = Engine( start_date = "2018-08-01", portfolio = ["BABA", "PDD", "KO", "AMD","^IXIC"], weights = [0.2, 0.2, 0.2, 0.2, 0.2], # equal weighting is set by default benchmark = ["SPY"] # SPY is set by default )

empyrial(portfolio)

give me a following error:

TypeError: float() argument must be a string or a number, not 'DataFrame'

Could anyone to help me with this issue?

Thanks

pip install --upgrade matplotlib
pip install --upgrade quantstats

This fixed it for me. Idk if both need to be updated or just one of them.
