我是用硒来打开一个网站。具体来说。
https://storage.googleapis.com/tfjs-models/demos/posenet/camera.html
但是当它用 无头模式它显示以下错误。

经过大量的搜索，我试过了:
options.add_argument("--disable-user-media-security=true")
options.add_argument('--headless')
options.add_argument("--no-sandbox")
options.add_argument("--use-fake-ui-for-media-stream")
options.add_argument("--disable-gpu")
options.add_argument("--disable-software-rasterizer")
options.add_argument('--disable-gpu')
options.add_argument("--window-size=1280,1024")
options.add_argument('--disable-dev-shm-usage')
options.add_argument('--ignore-gpu-blacklist')
options.add_argument('--use-gl')
options.add_argument("--user-data-dir=C:/Users/user_name/AppData/Local/Google/Chrome/User Data")
driver = webdriver.Chrome(options=options)
driver.maximize_window()
driver.set_window_size(1200, 600)
driver.set_window_size(1280, 1024)
driver.get("https://storage.googleapis.com/tfjs-models/demos/posenet/camera.html")
当然不是一次使用所有的参数，而是在不同的时间使用不同的参数块。不过有一点需要注意的是，当我使用参数 --无沙盒，错误变为

而且还能用。但与非无头模式相比，它是非常非常慢。
而且我不能用速度进行交易。我怎样才能解决这个问题？

...意味着ChromeDriverChrome进程无法移动缓存文件夹。..\Default\GPUCache 到 ../AppData/Local/Google/Chrome/User Data\Default\old_GPUCache_000.
根据该条 无头：使--disable-gpu标志成为不必要的。 很多文章、文档和指南都推荐使用 --disable-gpu 标榜 libosmesa.so 并不存在。有了合并后的 无头。从osmesa切换到SwiftShader 这个标志在Linux或macOS上已不再需要。随着合并后的 始终使用SwiftShader来处理无头Chrome浏览器。 这个标志在Windows上也是不必要的。
作为解决方案，你需要删除以下参数。
--disable-gpu--disable-software-rasterizer你可以在以下文章中找到一些相关的讨论。
此外，当试图访问一个特定的 浏览器简介 不提上面 User Data 目录中，你需要更深入一步，并提到了 资料目录 如 ../User Data/Profile 2 如下。
options.add_argument("--user-data-dir=C:/Users/user_name/AppData/Local/Google/Chrome/User Data/Profile 2")
你可以在以下几个相关讨论中找到。
