在python中引导DataFrame

Question

我正在尝试使用bootsrtaping技术重新取样我的数据集但没有成功，我的代码如下：

import pandas as pd
import numpy as np
from openpyxl import Workbook
from pandas import ExcelWriter
import matplotlib.pyplot as plt
import bootstrap as btstrap
#import scikits.bootstrap as sci
from matplotlib import pyplot as plt
import numpy.random as npr
sta_9147="//Users/talhadidi/Private/Desktop/9147.xlsx"
xlsx=pd.ExcelFile(sta_9147)
df1=pd.read_excel(xlsx,'Sheet1')
df1.columns=df1.columns.astype(str)
x_resample = btstrap(['AveOn','AveOff','AveLd','DOOR_OPEN_SEC'], n=10000)
writer=pd.ExcelWriter("/ Users/talhadidi/Private/Desktop/testt5.xlsx")
df2.to_excel(writer,'Sheet1')
writer.save()

我一直得到的错误是： TypeError：'module'对象不可调用， 任何人都可以帮忙，特别感谢提前。
