[f5-ansible]

run my code as doc write, nothing happen in win or mac:

import pandas as pd
import matplotlib.pyplot as plt
import numpy as np
from adtk.data import validate_series
from adtk.visualization import plot
from adtk.transformer import RollingAggregate
from adtk.transformer import DoubleRollingAggregate
from adtk.detector import ThresholdAD
#dt1 = pd.date_range(start="20190101", end="20190831", freq="D")
dt2 = pd.date_range(start="20190101", periods=10, freq="10D")
df2 = pd.DataFrame(np.arange(20).reshape((10, 2)), index=dt2,columns=['A','B'])
print(df2)
#print(df2.index)
df2 = validate_series(df2)
plot(df2)

I encountered the same problem, and I reported an error. How to solve this problem temporarily?

My question link: ValueError: Multi-dimensional indexing (e.g. obj[:, None]) is no longer supported. Convert to a numpy array before indexing instead.

In the file of https://github.com/arundo/adtk/blob/v0.6.2/tests/test_visualization.ipynb, The example does not use df, does it mean it does not support df?
