Python selenium webdriver "Session not created" exception when opening Chrome

Question

Here's my code for opening Chrome:

from selenium import webdriver 
driver=webdriver.Chrome('C:\\Users\\Imran\\AppData\\Local\\Programs\\Python\\Python36\\selenium\\chromedriver.exe')

Error when running program:

Traceback (most recent call last):
  File "C:/Users/Imran/PycharmProjects/webscraping/WF Item.py", line 6, in <module>
    driver = webdriver.Chrome('C:\\Users\\Imran\\AppData\\Local\\Programs\\Python\\Python36\\selenium\\chromedriver.exe')
  File "C:\Users\Imran\AppData\Local\Programs\Python\Python36\lib\site-packages\selenium\webdriver\chrome\webdriver.py", line 69, in __init__

    raise exception_class(message, screen, stacktrace)

Getting the following exception:

selenium.common.exceptions.WebDriverException: Message: session not created exception

@Romain Jouin Please download update version of chromedriver — Imran Rafiq, Aug 08 '19 at 05:42

Update your chromedriver to 2.24 version from the given url:

http://chromedriver.storage.googleapis.com/index.html?path=2.24/

That worked for me.

I can't really understand how do we update chromedriver ? I have a [chromedriver] in [ ~/anaconda/bin ] => should I download, unzip and replace the [chromedriver] file with the newly unzipped [chromedriver] file ? – Romain Jouin Nov 04 '16 at 15:05
I'm using apt-get way for installing/updating on my linux sysyem – Erez Weinstein Nov 17 '16 at 10:05

Setting LANG=en_US.UTF-8 before executing my script works for me. See this: https://bugs.chromium.org/p/chromedriver/issues/detail?id=1552#c43

In Python:

import os
os.environ["LANG"] = "en_US.UTF-8"

To install the chromedriver on windows, download and unzip the chromedriver_win32.zip and add the path to the folder containing the chromedriver.exe in the environment variables setting [System properties - Advanced system settings - Environment variables].
