Selenium.common.exceptions.WebDriverException:Message:Service Chromium-browser Unexpectedly exited

Python novice. Today in learning python to open Chrome browser using selenium and Webdriver, I encountered two problems

From selenium import webdriver
browser = webdriver.chrome ("Chromium-browser")
browser.get ("http://www.baidu.com")

Then the error is as follows:

Traceback (most recent call last):
File "test.py", line 3, in < module >
Browser = Webdriver. Chrome ("Chromium-browser")
File "/usr/lib/python2.7/selenium/webdriver/chrome/webdriver.py", line, in _ Init_
Self.service.start ()
File "/usr/lib/python2.7/selenium/webdriver/common/service.py", line, in start
Self.assert_process_still_running ()
File "/usr/lib/python2.7/selenium/webdriver/common/service.py", line 109, in assert_process_still_running
% (Self.path, Return_code)
Selenium.common.exceptions.WebDriverException:Message:Service Chromium-browser unexpectedly exited. Status Code was:0

The reason for this mistake is webdriver. Chrome ("Chromium-browser"), the parameters should not be Chrome browser, but should be chromedriver, so download chromedriver can, my system is Ubuntu 14.04, download decompression after the move to/usr/ Bin directory.

A new problem is encountered when you change the following:

From selenium import webdriver
browser = webdriver.chrome ("Chromedriver")
browser.get ("http://www.baidu.com ")

Traceback (most recent call last):
File "test.py", line 4, in < module>
Browser.get (' http://www.baidu.com ')
File "/usr/lib/python2.7/selenium/webdriver/remote/webdriver.py", line 264, in get

Do not know the specific reasons, welcome to know the friend to tell, on Google saw a friend write code, tried, the result of the problem solved, successfully opened the page.

import os from selenium import webdriver chromedriver = "/usr/bin/chromedriver" Webdriver.chrome.driver "] = chromedriver browser = webdriver. Chrome (' Chromedriver ') browser.get (' http://www.baidu.com ')
