解决方法

报错全称为：ValueError: data must be a 2 column data.frame, with thefirst column being a set of timestamps, and the second coloumn being numeric values.

这是因为数据格式错了，正确的数据格式应该是：一列是时间格式(datetime格式)，一列是值

报错原因

类似下面的这个demo

from pyculiarity import detect_ts
import pandas as pd
import numpy as np

data = pd.DataFrame(data={
    'time': pd.date_range('2020-01-01', periods=100, freq='D'),
    'data': np.random.randint(0, 20, 100),
})

results = detect_ts(data, max_anoms=0.02, direction='both', only_last='day')
