我在ubuntu服务器上运行jupyter笔记本。我正在尝试使用chromedriver运行下面的selenium代码。我得到了下面的错误，但如果我在Ubuntu终端中运行下面的代码行，它会返回下面的输出。有人知道这个问题可能是什么吗？我对ubuntu还是很陌生的。
Ubuntu代码：

chrome_options.add_argument("no-sandbox")
chrome_options.add_argument("--disable-extensions")
chrome_options.add_argument("--headless")出于某种原因，将上面的代码行添加到我的代码中就解决了这个问题。我在下面的帖子中找到了代码。

此错误消息...
WebDriverException: Message: unknown error: Chrome failed to start: exited abnormally
(unknown error: DevToolsActivePort file doesn't exist)
(The process started from chrome location /usr/bin/google-chrome is no longer running, so ChromeDriver is assuming that Chrome has crashed.)
(Driver info: chromedriver=74.0.3729.6 (255758eccf3d244491b8a1317aa76e1ce10d57e9-refs/branch-heads/3729@{#29}),platform=Linux 4.15.0-46-generic x86_64)...implies表示ChromeDriver无法启动/衍生新的WebBrowser，即Chrome Browser会话。
您的主要问题是您正在使用的二进制文件版本之间的incompatibility，如下所示：
- 您正在使用chromedriver=74.0.3729.6
- 发行说明中明确提到了以下内容:
支持Chrome v74
您可能正在使用Chrome浏览器的最新GAed版本，即
因此，ChromeDriver v74.0.3729.6和Chrome浏览器v73.x之间存在明显的不匹配
解决方案
- 将ChromeDriver降级到ChromeDriver v73.0.3683.68级别。
- 将Chrome版本保持在Chrome v73级别。在集成开发环境中调用项目工作区，并使用所需的依赖项在
@Test. - Always中重新生成项目。在
tearDown(){}方法中调用driver.quit()以正常关闭和销毁WebDriver和Web客户端实例。
