How do we use pyfolio with custom data?

I want to use pyfolio with custom data

This is what I have done

import pandas as pd
import pyfolio as pf
import numpy as np

dates = pd.date_range(start='2017-01-01',end='2017-12-31', freq=pd.tseries.offsets.BDay())
data = np.random.rand(260)
df = pd.DataFrame({'dates':dates,'col':data})
df = df.set_index('dates')
pf.create_returns_tear_sheet(df['col'])

the end result is this error

The current behaviour of 'Series.argmin' is deprecated, use 'idxmin' instead. The behavior of 'argmin' will be corrected to return the positional minimum in the future. For now, use 'series.values.argmin' or 'np.argmin(np.array(values))' to get the position of the minimum row.
