TypeError: ‘tuple‘ object is not callable

复现机器学习KNN出现的错误。

def createDataset():
    group = array([[1.0, 1.1],[1.0, 1.0], [0, 0], [0, 0.1]])
    labels = ['A','A','B','B']
    return group, labels

def classify0(inX, dataSet, labels, k):
    dataSetSize = dataSet.shape(0)
    diffMat = tile(inX, (dataSetSize, 1))- dataSet
    sqdiffMat = diffMat**2
    sqDistances = sqdiffMat.sum(axis=1)
    distances = sqDistances**0.5
    sortedDistIndicies = distances.argsort()
    classCount={}
    for i in range(k):
        voteIlabel = labels[sortedDistIndicies[i]]
        classCount[voteIlabel] = classCount.get(voteIlabel, 0) + 1
    sortedClassCount = sorted(classCount.iteritems(),key = operator.itemgetter(1),reverse=True
    )
    return sortedClassCount[0][0]在这里插入代码片

第一个错误
TypeError: ‘tuple’ object is not callable
将下列代码

   dataSetSize = dataSet.shape(0)

改成`

   dataSetSize = dataSet.shape[0]

对于数据特征的引用一般都用[]

data.feature[index]

第二个错误：
AttributeError: ‘dict’ object has no attribute ‘iteritems’

 sortedClassCount = sorted(classCount.items(),key = operator.itemgetter(1),reverse=True

中iteritems改成items
