在csv文件写入时,遇到隔一行输入的情况

当没有newline ='',时,隔一行插入一行,解决方式就是加上newline ='':

with open(os.path.join(self.root, filename), mode='w', newline='') as f:  # newline=''的作用是防止每一行数据后面都自动增加了一个空行。
    writer = csv.writer(f)
    for img in images:  # 'pokemon\\bulbasaur\\000000.png'
        name = img.split(os.sep)[-2]  # 用os.sep切割具有通用性,自动识别路径分隔符windows 和  linus
        label = self.name2label[name]
        writer.writerow([img, label])
    print('write into csv file:', filename)
