How do I fix this error in selenium webdriver?

I am using selenium pyhthon to try and open amazon.com in google chrome, but I keep getting this error message when I run the code.
selenium.common.exceptions.WebDriverException: Message: unknown error: cannot find Chrome binary
I have tried to search up this error on stackoverflow, but all I can find is Selenium gives "selenium.common.exceptions.WebDriverException: Message: unknown error: cannot find Chrome binary" on Mac, which I cannot understand. I am using mac M1 and I have the chrome version 92.0.4515.107. My code is
from selenium import webdriver
chrome_driver_path = "/Users/asznee/selenium/chromedriver"
driver = webdriver.Chrome(chrome_driver_path)
driver.get("https://www.amazon.com")

See your Google chrome is not installed in default location which is
C:\Program Files\Google\Chrome\Application
it is installed :
C:\Users\asznee\Desktop\Downloads\Google Chrome\Application
right ?
so for solving this issue, your chromdriver.exe needs to know where Google chrome is installed :-
You can try the below code :-
options = webdriver.ChromeOptions()
options.binary_location = "/Users/asznee/Desktop/Downloads/Google Chrome/Application/chrome"
chrome_driver_binary = "/Users/asznee/selenium/chromedriver"
driver = webdriver.Chrome(chrome_driver_binary, options = options)

there is no need to specify the path of the chrome driver just keep the chrome driver in the project
just copy and paste in the project
and start initializing the web driver
simply start typing with
WebDriver driver = new ChromeDriver();
and enter the URL of the application
and follow the code

WebDriver driver = new ChromeDriver();
WebDriver is having unimplemented methods
here is chrome driver is implementing these unimplemented methods
chrome driver is just the driver which you're telling the selenium to run the test on the chrome browser.
you can download it on the
https://chromedriver.chromium.org/home
if you want to work with the firefox browser you use the gecko driver.

Selenium driven ChromeDriver can't find Chrome binary

I just uninstalled Chrome because it was acting strange (fixed now) and after this Selenium in Python is not able to identify the Chrome driver binary, which is extremely strange because it should be completely unaffected and it is in a different location and a different version from the chrome I use on my desktop, code is as follows and has worked for years now.
chrome_options = webdriver.ChromeOptions()
chrome_options.add_argument('--load-extension='+exension_path)
driver = webdriver.Chrome(executable_path=chrome_driver_folder,options=chrome_options)
Anyone has any idea what on earth is going on? I get the follow error:
WebDriverException: Message: unknown error: cannot find Chrome binary
(Driver info: chromedriver=2.40.565498 (ea082db3280dd6843ebfb08a625e3eb905c4f5ab),platform=Windows NT 10.0.18362 x86_64)

This error message...
WebDriverException: Message: unknown error: cannot find Chrome binary (Driver info: chromedriver=2.40.565498 (ea082db3280dd6843ebfb08a625e3eb905c4f5ab),platform=Windows NT 10.0.18362 x86_64)
...implies that the ChromeDriver was unable to initiate/spawn a new Browsing Context i.e. Chrome Browser session.
Your main issue is the incompatibility between the version of the binaries you are using as follows:
You are using chromedriver=2.40
Release Notes of chromedriver=2.40 clearly mentions the following :
Supports Chrome v66-68
As you have uninstalled Chrome and reinstalled presumably you are using the latest chrome=85.0
Release Notes of ChromeDriver v85.0 clearly mentions the following :
Supports Chrome version 85
So there is a clear mismatch between ChromeDriver v2.40 and the Chrome Browser v85.0
Solution
Ensure that:
Selenium is upgraded to current released Version 3.141.59.
ChromeDriver is updated to current ChromeDriver v85.0 level.
Chrome is updated to current Chrome Version 85.0 level. (as per ChromeDriver v85.0 release notes)
If your base Web Client version is too old, then uninstall it and install a recent GA and released version of Web Client.
Clean your Project Workspace through your IDE and Rebuild your project with required dependencies only.
Execute your #Test as non-root user.
Always invoke driver.quit() within tearDown(){} method to close & destroy the WebDriver and Web Client instances gracefully.

In order to have a clean code and to stop track the chrome path/version, I recommend to you to use webdriver_manager
Install it
pip install webdriver_manager
and use it like this
from webdriver_manager.chrome import ChromeDriverManager
options = webdriver.ChromeOptions()
chrome_options.add_argument('--load-extension='+exension_path)
driver = webdriver.Chrome(executable_path=ChromeDriverManager().install(), options=options)
but if don't want to use it here is the code for local browser
chrome_options = Options()
chrome_options.add_argument('--load-extension='+exension_path)
chrome_options.binary_location = 'YOUR_PATH'
driver = webdriver.Chrome(executable_path=os.path.abspath(“chromedriver"), chrome_options=chrome_options)
but I totally recommend using the first version.

Python, PhantomJS says I am not using headless?

my code is:
from selenium import webdriver
driver = webdriver.PhantomJS(executable_path='driver/bin/phantomjs.exe')
driver.get("https://www.test.com")
print(driver.current_url)
It seems to run fine but before it runs I always get this error:
UserWarning: Selenium support for PhantomJS has been deprecated, please use headless versions of Chrome or Firefox instead warnings.warn('Selenium support for PhantomJS has been deprecated, please use headless
Why am I getting this error? I thought my PhantomJS was headless as it still works and no browser pops-up is this error save to ignore?

Selenium considers PhantomJS as deprecated, so you need to us either Chrome or Firefox in headless mode.
Here are the steps to use Chrome in headless mode:
download chrome driver from https://sites.google.com/a/chromium.org/chromedriver/getting-started
extract it to a folder
add this folder to your PATH environment variable (if you don't do it, you will have to use webdriver.Chrome('/your/path/to/chromedriver') in the code below instead of webdriver.Chrome())
Then use it like this:
from selenium import webdriver
# prepare the option for the chrome driver
options = webdriver.ChromeOptions()
options.add_argument('headless')
# start chrome browser
browser = webdriver.Chrome(chrome_options=options)
browser.get('http://www.google.com/xhtml')
print(browser.current_url)
browser.quit()
More on how to use ChromeDriver
For the other options: here (also here and here)

In Selenium 3.8.1 PhantomJS marked as deprecated webdriver and recommend us to use either Chrome or Firefox in headless mode.

You could use this:
from selenium import webdriver
browser = webdriver.Chrome('chromedriver_path/chromedriver')
browser.get("https://www.test.com")
print(browser.current_url)
browser.quit()

Found an alternative you can add options.add_argument('headless') to chrome

Selenium-Python with chromium browser (windows)

I am trying to launch chromium browser with selenium python on windows 8.
Added binary_location as chromium binary location which is appdata.
But still chromedriver starts google chrome instead of chromium.
If I uninstall google chrome, then chromedriver by default launches chromium. But with chrome installed it always launches chrome regardless.
Does anyone have an idea on how to start chromium with selenium while chrome installed?
Please do not mark it as duplicate. The other one was about unix and solution provided to selenium java while this one is about windows and python.

Try this:
from selenium.webdriver.chrome.options import Options
options = Options()
options.binary_location = r"D:\.....\chrome.exe"
# This line defines your Chromium exe file location.
driver = webdriver.Chrome(chrome_options=options)
driver.get('https://www.google.com/')
Worked for me.
I installed both Chrome and Chromium.
It starts the specified exe.

To start Chromium browser you can use the following code block :
from selenium import webdriver
from selenium.webdriver.chrome.options import Options
options = Options()
options.binary_location("C:\\path\\to\\chrome.exe") //path to chromium binary
options.add_argument("start-maximized")
options.add_argument("--disable-gpu-vsync") //only for Windows
options.add_argument("--remote-debugging-port=9222") //for MAC & Linux
driver = webdriver.Chrome(executable_path=r'C:\path\to\chromedriver.exe', chrome_options=options)
driver.get('http://google.com/')

Selenium Chromedriver not working in Python, Centos Cpanel Server

I installed selenium and chrome driver.
I then created the below code to run it:
from pyvirtualdisplay import Display
from selenium import webdriver
chromedriver = "/usr/bin/chromedriver"
driver = webdriver.Chrome(chromedriver)
driver.get(url)
html = driver.page_source
driver.quit()
display.stop()
The code yields the following error: "'chromedriver.exe' executable needs to be in PATH. Please see https://sites.google.com/a/chromium.org/chromedriver/home"
The path is correct. I have tried some variations of the code but they all yield the same message. My webhost claims you cant install selenium on a centos server that has cpanel. Is this true or is there something wrong with my code?

you might use OS.environ and chromeoptions
