问题麻烦老师帮忙看看呢，这个和selenium版本有关系吗？
from selenium import webdriver
from selenium.webdriver import ActionChains
from selenium.webdriver.common.by import By
class TestAction:
def setup(self):
option = webdriver.ChromeOptions()
option.add_experimental_option('w3c',False)
self.driver = webdriver.Chrome(options=option)
self.driver.get("https://www.baidu.com/s?wd=%E9%93%B8%E7%89%A2%E4%B8%AD%E5%8D%8E%E6%B0%91%E6%97%8F%E5%85%B1%E5%90%8C%E4%BD%93%E6%84%8F%E8%AF%86&sa=fyb_n_homepage&rsv_dl=fyb_n_homepage&from=super&cl=3&tn=baidutop10&fr=top1000&rsv_idx=2&hisfilter=1")
self.driver.implicitly_wait(5)
def test_roll(self):
# 创建一个ActionChains对象
actions = ActionChains(self.driver)
# 将鼠标移动到需要滑动的位置（例如页面顶部）
actions.move_to_element_with_offset(self.driver.find_element(By.XPATH, '//*[@id="su"]'), xoffset=0, yoffset=0)
# 按住鼠标左键
actions.click_and_hold()
# 设置滑动距离和方向（例如向下滑动1000像素）
actions.move_by_offset(0, -1000)
# 释放鼠标左键
actions.release()
# 执行滑动操作
actions.perform()
