python中的sqrt和浮点数据

Question

我的代码中有一些问题 其结果错误“AttributeError:“Series”对象没有属性“float”

我需要解决这个问题的办法

我的代码

def calculateED (pdX, pdY):
arg = (((pdX['NormalTemp']-pdY[0])**2)+
    ((pdX['NormalHumidity']-pdY[1])**2)+
    ((pdX['NormalOutlook']-pdY[2])**2)+
    ((pdX['NormalWindy']-pdY[3])**2)).float()
pdX['ED']= math.sqrt(arg1)
return pdX

dataTest = [64.0,65.0,1.0,1.0]
ngitung = calculateED(dataset, dataTest)
ngitung.sort_values(by=['ED'])

但是在运行这个代码之后，我遇到了一些问题

---------------------------------------------------------------------------

根据这项{a1}：

numpy functions require float type argument explicity

例如：

import numpy as np
your_array = your_array.float()
output = np.exp(your_array)

就你而言：

def calculateED (pdX, pdY):

    argument = ((pdX['NormalTemp']-pdY[0])**2)+
    ((pdX['NormalHumidity']-pdY[1])**2)+
    ((pdX['NormalOutlook']-pdY[2])**2)+
    ((pdX['NormalWindy']-pdY[3])**2).float()

    pdX['ED']= np.sqrt(argument)

    return pdX
