WebDriverException in Selenium using python 3

Question

I am using python 3 on windows, using the Selenium package for web crawling using Chrome. I am running on a new computer, doing everything the same, but get the following error immediately in the first run. I never saw this exception. Anyone is familiar with it and can shed some light? Thanks.

    WebDriverException: session not created exception
    from unknown error: Runtime.executionContextCreated has invalid 'context': {"auxData":{"frameId":"9668.1","isDefault":true},"id":1,"name":"","origin":"://"}
      (Session info: chrome=54.0.2840.71)
      (Driver info: chromedriver=2.22.397933 (1cab651507b88dec79b2b2a22d1943c01833cc1b),platform=Windows NT 6.3.9600 x86_64)

The exception happens immediately at the beginning at the driver call:

    driver = webdriver.Chrome()

UPDATE: after upgrading to chromeDriver2.4, there is a different error which I never saw before:

WebDriverException: unknown error: unable to discover open pages (Driver info: chromedriver=2.4.226107,platform=Windows NT 6.1 SP1 x86_64)

Any ideas?? Thanks...

There is no need, as the chromedriver.exe is in the working directory... I don't think that's the problem — splinter

Make sure to update to the latest driver. I had the same problem--was using using 2.22 and updated to 2.24. Solved the issue.

Forlatest driver see here: (Click latest release) http://chromedriver.storage.googleapis.com/index.html

Thanks @DanielGlasgow. I did that, but now am getting a different error in the driver = webdriver.Chrome() line: WebDriverException: unknown error: unable to discover open pages (Driver info: chromedriver=2.4.226107,platform=Windows NT 6.1 SP1 x86_64)
