我正在使用Selenium WebDriver(v2.5.0).当我使用driver.click(...)"命令时,我收到此错误

Element is not currently visible and so may not be interacted with Build info: version: '2.5.0', revision: '13516', time: '2011-08-23 18:30:44' System info: os.name: 'Linux', os.arch: 'amd64', os.version: '2.6.38-10-generic', java.version: '1.6.0_26' Driver info: driver.version: RemoteWebDriver

在鼠标悬停在元素上的浏览器中,单击的元素变为可见.有没有办法检查某些东西是否可见？

我已经尝试过这个页面的方法： 在 Python 中使用 Selenium 上传文件

代码：

file_button = browser.find_element_by_id('fileUploadProxy')
file_button.send_keys('/Users/home/Downloads/1-Students-and-Parent-Email.csv')

但我收到以下错误：
