selenium 无法启动chrome

我名骷髅

selenium是 3.4.2        chrome是57.0    也下载了chromedriver 2.29  但是就是打不开chrome，打开火狐也是莫名其妙的错误，这是不是python版本的


问题

>>> browser = webdriver.Chrome()
Traceback (most recent call last):
  File "<pyshell#12>", line 1, in <module>
    browser = webdriver.Chrome()
  File "E:\python\lib\site-packages\selenium-2.25.0-py3.6.egg\selenium\webdriver\chrome\webdriver.py", line 62, in __init__
