为什么没有定义显示驱动程序

Question

我试图让我的脚本的这一部分从文件夹“zip code pics”上传图像，该文件夹包含由可选邮政编码命名的子文件夹

当我到达图片上传页面时，它告诉我错误驱动程序未定义..

我在这里缺少什么？

def picturetime():
    zipcode = get_zipcode()
    while True:
          try:
            pics = []
            for each in os.listdir(os.path.join(os.curdir, 'ZIP CODE PICS', zipcode[0])):
                name = os.path.splitext(each)
                picture_name = os.path.join(os.curdir, 'ZIP CODE PICS',zipcode[0] , each)
                picture_name = os.path.abspath(picture_name)
                pics.append(picture_name)
            if pics:
                picture_name = random.choice(pics)
                driver.find_element_by_id('plupload').send_keys(picture_name)
                print('[zip code image] clicking on save_link after picture')
                sleep(10)
