我正试图在带有selenium和python的Linux Centos 7服务器上使用无头chrome。我在尝试激活驱动程序时遇到以下错误：
Traceback (most recent call last):

selenium.common.exceptions.SessionNotCreatedException: Message: session not created
from disconnected: unable to connect to renderer
(Session info: headless chrome=80.0.3987.116)
我的版本：
- Chromedriver版本80.0.3987.106
- 谷歌铬80.0.3987.116
有人能帮我吗？
此错误消息。。。
selenium.common.exceptions.SessionNotCreatedException: Message: session not created
from disconnected: unable to connect to renderer
(Session info: headless chrome=80.0.3987.116)
意味着ChromeDriverv80.0无法启动/生成新的浏览上下文，即Chrome浏览器会话。
根据讨论，WebDriver 80.0.3987.16无法在Linux上打开Chrome。@triciac更新了这一点，ChromeDriver v80.0的实现按以下顺序查找Chrome：
- locations->push_back(base:：FilePath("/usr/local/sbin"((
- locations->push_back(base:：FilePath("/usr/local/bin"((
- locations->push_back(base:：FilePath("/usr/sbin"((
- locations->push_back(base:：FilePath("/usr/bin"((
- locations->push_back(base:：FilePath("/sbin"((
- locations->push_back(base:：FilePath("/bin"((
- locations->push_back(base:：FilePath("/opt/google/chrome"((；//最后一次尝试使用默认安装位置
@johnchen证实，Linux上的二进制搜索顺序被r708243意外更改，这是为了更容易配置Chrome二进制文件的名称，但也意外更改了搜索顺序。
ChromeDriver团队已更新ChromeDriver，以通过此次修订/提交解决此问题。
解决方案
上述解决方案可用于：
- ChromeDriver v80.0.3987.106
- ChromeDriver v81.0.4044.20
临时解决方案
一个临时解决方案是使用binary_location属性，您可以在Selenium:WebDriverException中找到详细的讨论：Chrome无法启动：由于谷歌Chrome不再运行而崩溃，因此ChromeDriver假设Chrome已崩溃
