# 1.打开首页
driver.get('https://www.geetest.com/adaptive-captcha-demo')

# 2.点击【文字点选验证】
tag = WebDriverWait(driver, 30, 0.5).until(lambda dv: dv.find_element(
    By.XPATH,
    '//*[@id="gt-showZh-mobile"]/div/section/div/div[2]/div[1]/div[2]/div[3]/div[4]'

# 3.点击开始验证

# 识别图片
bg_tag = driver.find_element(

time.sleep(2000)
driver.close()

2.目标识别

截图每个字符，并基于ddddocr识别。

3.背景坐标识别

识别背景中的文字，并获得字体的坐标（后续需按照顺序点击）

3.1 ddddocr

能识别，但是发现默认识别率有点低，想要提升识别率，可以搭建Pytorch环境对模型进行训练，参考：https://github.com/sml2h3/dddd_trainer

4.坐标点击

根据坐标，在验证码上进行点击。

ActionChains(driver).move_to_element_with_offset(标签对象, xoffset=x, yoffset=y).click().perform()
