这是什么错啦？求解

Question

def trainNB0(trainMatrix, trainCategory):   

    numTrainDocs = len(trainMatrix)   

numWords = len(trainMatrix[0])    

    pAbusive = sum(trainCategory) / float(numTrainDocs)  

    p0Num = zeros(numWords); p1Num = zeros(numWords)   

    p0Denom = 0.0; p1Denom = 0.0 

    for i in range(numTrainDocs):   

        if trainCategory[i] == 1:   

            p1Num += trainMatrix[i]    

            p1Denom += sum(trainMatrix[i])   

        else:    

            p0Num += trainMatrix[i]    

            p0Denom += sum(trainMatrix[i])   

    p1Vect = p1Num / p1Denom

    p0Vect = p0Num / p0Denom 

    return p0Vect, p1Vect, pAbusive

Answer 1

要先import bayes，才能reload(bayes)吧
