我试图上传图片在谷歌教学机使用 selenium 在Python中，因为有太多的我手动完成。
当NoSuchElementException明显存在时，我总是得到它。

driver.find_element(By.CSS_SELECTOR, ".add-classes").click()

现在它发生在：因为我已经加了密码。
iframe=驱动程序。查找元素（按.标签名称，“HTML集合[]”）Web驱动程序等待（驱动程序，10）.直到（错误代码.框架将可用并切换到它（（按.名称，iframe）））Web驱动程序等待（驱动程序，20）.直到（错误代码.元素将可单击（（按.CSS选择器，“.添加类”）））.单击（）
我怎样才能让它工作呢？

我试过切换到iframe。

document.getElementsByTagName("iframe")

在页面的控制台中运行这个命令会得到一个可疑的答案：HTMLCollection []。我试着切换到它，你可以看到下面的完整代码：iframe=驱动程序.find_element（通过.标签名称，“HTML集合[]”）
我也试过等待页面加载：

WebDriverWait(driver, 10).until(EC.frame_to_be_available_and_switch_to_it((By.NAME,iframe)))
WebDriverWait(driver, 20).until(EC.element_to_be_clickable((By.CSS_SELECTOR, ".add-classes"))).click()
