写python爬虫的过程中，碰到一个 一直报platform_sensor_reader_win.cc(242)] NOT IMPLEMENTED的问题，虽然程序可以执行，但是一直报，不方便调试等。

命令行报错如下：

>main.py

在国内外的网站上根据报错platform_sensor_reader_win.cc(242) 或者 NOT IMPLEMENTED查找解决办法，试了好多方式都不能解决，像给Chromedriver加参数：

    options.add_argument('--disable-gpu')

    options.add_argument('--ignore-certificate-errors')

    options.add_argument('--ignore-ssl-errors')

    options.add_experimental_option("excludeSwitches", ["ignore-certificate-errors", "safebrowsing-disable-download-protection", "safebrowsing-disable-auto-update", "disable-client-side-phishing-detection"])

    options.add_argument('--silent')

以上方式，经尝试，均不行

最终从 DevTools listening on 着手

于 http://www.javaear.com/question/47392423.html 找到限制报错等级的方法：

    options.add_argument('--log-level=3')

记录一下，方便以后查找
