chrome driver install with selenium

I have properly install selenium and chromedriver and wanted to execute this below code at python
import selenium
from selenium import webdriver
driver = webdriver.Chrome(executable_path=r"C:\Users\SM.Nibir\Desktop\Python\chromedriver_win32\chromedriver.exe")
but I am getting these errors on my output panel
During handling of the above exception, another exception occurred:
Traceback (most recent call last):
File "c:/Users/SM. Nibir/Desktop/Python/import os.py", line 3, in <module>
driver = webdriver.Chrome()
File "C:\python\lib\site-packages\selenium\webdriver\chrome\webdriver.py", line 73, in __init__
self.service.start()
File "C:\python\lib\site-packages\selenium\webdriver\common\service.py", line 81, in start
raise WebDriverException(
selenium.common.exceptions.WebDriverException: Message: 'chromedriver' executable needs to be in PATH. Please see https://sites.google.com/a/chromium.org/chromedriver/home
Who can I solve this problem and make this code work properly?

first of all, your first mistake is that you wrote "import selenium from.."
so the order has to be that way:
from selenium import webdriver
driver=webdriver.Chrome(executable_path=r"C:\Users\...chromedriver.exe")
ofcourse that you need to change the path for the correct location of your chromedriver.exe file.
let me know if it helps.

How to run selenium webdriver with Python in CentOS 6.10 with Firefox

I'm trying to run a Python script in a CentOS server. However, I've been unable to install Google Chrome (I've read it is no longer supported by CentOS) so I decided to try with Firefox. However, I get the following error when trying to run it with Firefox.
Traceback (most recent call last):
File "/home/uscomplianceserv/public_html/scrapdata/FMCSAScraper.py", line 73, in <module>
init_selenium()
File "/home/uscomplianceserv/public_html/scrapdata/FMCSAScraper.py", line 40, in init_selenium
webdriver.Firefox(firefox_options = options, executable_path='/home/uscomplianceserv/public_html/scrapdata/geckodriver')
File "/usr/local/lib/python2.7/site-packages/selenium/webdriver/firefox/webdriver.py", line 133, in __init__
if options.binary is not None:
AttributeError: 'Options' object has no attribute 'binary'
This is what I'm using:
Centos 6.10
Python 2.7
Selenium 3.14.0
Firefox 45
Geckodriver v0.21.0
This is the selenium webdriver initialization function:
def init_selenium():
global driver, page
options = Options()
options.add_argument("-headless")
driver = webdriver.Firefox(firefox_options = options, executable_path='/home/uscomplianceserv/public_html/scrapdata/geckodriver')
driver.get(url)

Import Error Symbol not found: __PySlice_AdjustIndices

I am doing some beginner Selenium to automate a task in the browser. I have installed Selenium using pip install selenium and I know it installed successfully because I saw the following message: Successfully installed selenium-3.9.0.
Okay so that's clear Selenium is up and working.
I want to run this python file:
from selenium import webdriver
browser = webdriver.Firefox()
type(browser)
browser.get('http://inventwithpython.com')
However, when I run this using the terminal, I get the following error:
mustafas-mbp:PlayDivya mustafahoda$ python playDivya.py
Traceback (most recent call last):

Any help would be super helpful. This is a very simple script and I have no idea why this is happening!
Thanks in advance!

The error says it all :
Traceback (most recent call last):
File "playDivya.py", line 4, in <module>
from selenium import webdriver
.
ImportError: dlopen(/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/lib-dynload/array.so, 2): Symbol not found: __PySlice_AdjustIndices
Reasons and Solution
This issue can arise when you install a new version of python. In those cases you may need to run hash -r python to tell bash to reset the cached location to the python executable.
If hash -r python says too many args then you can use rehash command.
As per the discussion Symbol not found: __PyCodecInfo_GetIncrementalDecoder the issue occurs when Python is updated from Python 2.7.10 to 2.7.11.
If you are using conda package you need to run conda install python=2.7.10 which will solve this problem.
Even downgrading Python to 2.7.10 will also work.
The best solution would be Re-Installing Selenium.

Running Selenium on AWS Ubuntu - Error: Could not find firefox in your system PATH

I am running python 2.7.12 with selenium version 2.53.6 and firefox 46.0.1 on an AWS Ubuntu Server 16.04 LTS instance. I've installed pyvirtualdisplay.
When I run this code:
from pyvirtualdisplay import Display
from selenium import webdriver
display = Display(visible=0, size=(1024, 768))
display.start()
driver = webdriver.Firefox()
I get this error:
Traceback (most recent call last):
File "<stdin>", line 1, in <module>

I've tried to add a link to my bash profile
echo export 'PATH="$PATH:/home/firefox"' >> ~/.bashrc
But have not been successful. Any help would be greatly appreciated.

Splinter: DriverNotFoundError for zope.testbrowser

I am using Python Splinter to automate a website and to scrape data from it. When I use the default browser mode which is keeping blank in Browser() it opens firefox and completes the written task but, when I use the headless browser 'zope.testbrowser', I get the following error. What should I need to do here?
Traceback (most recent call last):
File "pysplinter.py", line 4, in <module>
browser = Browser('zope.testbrowser')
File "/usr/local/lib/python2.7/dist-packages/splinter/browser.py", line 62, in Browser
raise DriverNotFoundError("No driver for %s" % driver_name)
splinter.exceptions.DriverNotFoundError: No driver for zope.testbrowser

I don't know if this is still relevant, but will post anyway for the benefit of others.
I faced the same issue and my problem was that mechanize module was not installed.
Fix:
pip install mechanize
However, I faced another issue after this.
Explanation
That's the line of code that is failing in browser.py of splinter, but due to except: pass, it is being silently ignored. If executed manually, the root of the problem can be observed:
>>> from splinter.driver.zopetestbrowser import ZopeTestBrowser
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "/Users/rustam/.virtualenvs/python2/lib/python2.7/site-packages/splinter/driver/zopetestbrowser.py", line 19, in <module>
import mechanize
ImportError: No module named mechanize
