【解决方案1】：

错误说明了一切WebDriverException: unknown error: cannot get automation extension

根据您的Error Stack Trace，您正在使用：

chromedriver=2.29
chrome=62.0

chromedriver=2.29 的发行说明清楚地提到了以下内容：

Supports Chrome v56-58

chromedriver=2.33 的发行说明清楚地提到了以下内容：

Supports Chrome v60-62

解决办法：

解决方案是将 chromedriver 二进制文件升级到 v2.33 级别或将您的 Chrome Browser 二进制文件降级到 v56-58
