kaggle fashion-mnist.csv python的问题

Question

本人python小白，在网上东拼西凑弄的代码

 >>> def toInt(array):
    array=mat(array)
    m,n=shape(array)
    newArray=zeros((m,n))
    for i in range(m):
        for j in range(n):
            newArray[i,j]=int(array[i,j])
    return newArray

>>> def nomalizing(array):
    m,n=shape(array)
    for i in range(m):
        for j in range(n):
            if array[i,j]!=0:
                array[i,j]=1
    return array

>>> import csv
>>> def loadTrainData():
    l=[]
    with open('fashion-mnist_train.csv') as file:
        lines=csv.reader(file)
        for line in lines:
            l.append(line)
    l.remove(l[0])
    l=array(l)
    label=l[:,0]
    data=l[:,1:]
    return nomalizing(toInt(data)),toInt(label)

>>> def loadTestData():
    l=[]
    with open('test_data.csv') as file:
        lines=csv.reader(file)
        for line in lines:
            l.append(line)
    l.remove(l[0])
    l=array(l)
    data=l[:,1:]
    return nomalizing(toInt(data))

>>> def loadTestResult():
    l=[]
    with open('sample_submission.csv') as file:
        lines=csv.reader(file)
        for line in lines:
            l.append(line)
    l.remove(l[0])
    label=array(l)
    return toInt(label[:,1])
    >>> def classify0(inX, dataSet, labels, k):
    inX=mat(inX)
    dataSet=mat(dataSet)
    labels=mat(labels)
    dataSetSize = dataSet.shape[0]
    diffMat = tile(inX, (dataSetSize,1)) - dataSet
    sqDiffMat = array(diffMat)**2
    sqDistances = sqDiffMat.sum(axis=1)
    distances = sqDistances**0.5
    sortedDistIndicies = distances.argsort()
    classCount={}
    for i in range(k):
        voteIlabel = labels[0,sortedDistIndicies[i]]
        classCount[voteIlabel] = classCount.get(voteIlabel,0) + 1
    sortedClassCount = sorted(classCount.items(), key=operator.itemgetter(1), reverse=True)
    return sortedClassCount[0][0]
    >>> import KNN
>>> from numpy import *
>>> import operator
>>> def handwritingClassTest():
    trainData,trainLabel=loadTrainData()
    testData=loadTestData()
    testLabel=loadTestResult()
    m,n=shape(testData)
    errorCount=0
    resultList=[]
    for i in range(m):
        classifierResult = classify0(testData[i], trainData, trainLabel, 5)
        resultList.append(classifierResult)
        print ("the classifier came back with: %d, the real answer is: %d") % (classifierResult, testLabel[0,i])
        if (classifierResult != testLabel[0,i]): errorCount += 1.0
    print ("\nthe total number of errors is: %d") % errorCount
    print ("\nthe total error rate is: %f") % (errorCount/float(m))
    saveResult(resultList)
>>> handwritingClassTest()

运行了3个多小时，运行过程中的图片如下

结果如下

result.csv也在桌面上显示了，但是为0字节

求问各位大神，如何修改code呢？是不是再次运行还得3个小时呀、
