 29 | #### Selenium + Chrome Demo
 30 | 
 31 | `chrome.py`
 32 | 
 33 | ```
 34 | # coding:utf-8
 35 | import time
 36 | from selenium import webdriver
 37 | from pyvirtualdisplay import Display
 38 | 
 39 | display = Display(visible=0, size=(800, 800))
 40 | display.start()
 41 | 
 42 | driver = webdriver.Chrome()
 43 | 
 44 | driver.get('http://www.cnblogs.com/')
 45 | time.sleep(5)
 46 | 
 47 | title = driver.title
 48 | print(title.encode('utf-8'))
 49 | 
 50 | # html=driver.page_source
 51 | # print(html)
 52 | 
 53 | # Release memory
 54 | driver.close()
 55 | driver.quit()
 56 | display.stop()
 57 | ```
 58 | 
 59 | **Something Important**
 60 | 
 61 | If you run the  `chrome.py` file has error:
 62 | 
 63 | ```
 64 | Message: unknown error: Chrome failed to start: crashed
 65 | ```
 66 | 
 67 | And run `chromium-browser` has following error:
 68 | 
 69 | ```
 70 | # chromium-browser
 71 | Failed to move to new namespace: PID namespaces supported, Network namespace supported, but failed: errno = Operation not permitted
 72 | ```
 73 | 
 74 | Then to use the following method to solved it:
 75 | 
 76 | `chrome_fix.py`
 77 | 
 78 | ```
 79 | # coding:utf-8
 80 | import time
 81 | from selenium import webdriver
 82 | from selenium.webdriver.chrome.options import Options
 83 | from pyvirtualdisplay import Display
 84 | 
 85 | display = Display(visible=0, size=(800, 800))
 86 | display.start()
 87 | 
 88 | chrome_options = Options()
 89 | chrome_options.add_argument("--no-sandbox")
 90 | driver = webdriver.Chrome(chrome_options=chrome_options)
 91 | 
 92 | driver.get('http://www.cnblogs.com/')
 93 | time.sleep(5)
 94 | 
 95 | title = driver.title
 96 | print(title.encode('utf-8'))
 97 | 
 98 | # html=driver.page_source
 99 | # print(html)
100 | 
101 | # Release memory
102 | driver.close()
103 | driver.quit()
104 | display.stop()
105 | 
106 | ```
