如何让机器读懂就需要我们人为给每个类别打上标签

完整代码：

import os
import sys

path="H:\\CX\\A\\\\da\\train"
filenames=os.listdir(path) #读取path内所有文件名返回列表
i=0
with open("/HOG_SVM-master/lable\\train.txt", "w") as f:
        for filename in filenames:
                sub_path=path+"/"+filename+"/"
                pic=os.listdir(sub_path)
                print(filename+','+str(i))
                for p in pic:
                        f.write('train/'+filename+'/'+p+' '+str(i)+'\n')
                i=i+1
