如何处理python selenium chrome webdriver加载时卡住的问题

Question

总之，我正在分析我的instagram追随者，为了做到这一点，我在python中使用了selenium。 我使用下面的代码只是为了滚动窗口，当我点击“追随者”。（这个窗口在技术上是怎么称呼的？对话框？） 代码工作得很完美，正如你在我所附的屏幕截图中看到的那样，chrome卡住了，窗口不再允许向下滚动。在

代码：

    num_current_users_found = 0
    individual_user_class_when_scrolling  = 'NroHT'
    time.sleep(5)
    while (num_current_users_found / tot_actual_num_of_users *100) < 99:
        try:            
            visible_individual_users = driver.find_elements_by_class_name(individual_user_class_when_scrolling)
            print("scrolling to the bottom...    len(visible_individual_users) = ",str(len(visible_individual_users)), "  vs. expected total users = ", str(tot_actual_num_of_users))
            pre_scroll_num_of_visible_users = len(visible_individual_users)         
            last_visible_user_elem = visible_individual_users[-1]
            actions = ActionChains(driver)
            actions.move_to_element(last_visible_user_elem)
            actions.perform()
            random_sleep(0,2)
            last_visible_user_elem.location_once_scrolled_into_view
            visible_individual_users = driver.find_elements_by_class_name(individual_user_class_when_scrolling)
            num_current_users_found = len(visible_individual_users)

            if num_current_users_found == pre_scroll_num_of_visible_users:
                time.sleep(1)
        except:
            print("can't scroll anymore")

我如何处理chrome，而不关闭窗口与所有我的追随者，并把滚动一直推到底部？在
