Headless Edge Selenium Error: No browser is open

I'm trying to get Edge open Headless but I keep getting the error 'No browser is open'.
Here is the Python code:
from msedge.selenium_tools import EdgeOptions
from msedge.selenium_tools import Edge
def function():
edge_options = EdgeOptions()
edge_options.use_chromium = True
edge_options.add_argument('headless')
edge_options.add_argument('disable-gpu')
driver = Edge(executable_path='C:/Users/ID75143/PycharmProjects/TestProject/venv/Scripts/MicrosoftWebDriver.exe', options=edge_options)
No matter what I put after the last line (I've tried opening a URL and maximising the window), it says it's not possible because "No browser is open". I've tried opening Edge in headed mode and it works perfectly then, but not headless.
Anyone have a clue of what to do?

According to the code you provided, I found that you are using MicrosoftWebDriver. It is used in Legacy Edge, for more details, please check this: What is Microsoft Edge Legacy?
So I have to confirm again, are you using the correct version of Edge browser and Driver? Maybe you should try to upgrade them before testing.
Here is a simple test, and it works fine ( Version 91.0.864.48 ):
from msedge.selenium_tools import Edge, EdgeOptions
options = EdgeOptions()
options.use_chromium = True
options.add_experimental_option("prefs", {
"download.default_directory": r"E:\Downloads" #change the route you need
})
options.add_argument("headless")
options.add_argument("disable-gpu")
driver = Edge(executable_path= #put your edgedriver here
r'C:\Users\Administrator\Desktop\msedgedriver.exe', options=options)
driver.get("https://www.seleniumhq.org/download/");
m = driver.find_element_by_link_text("32 bit Windows IE")
m.click()

Instead of this :
edge_options.add_argument('headless')
do this :
edge_options.add_argument('--headless')

Error in python selenium 3 Edge web driver

I am a complete beginner to selenium and I wrote my first program just to connect to Google.
from selenium import webdriver
path = "C:\\Users\\Home\\Documents\\Python37-32\\Scripts\\Code\\msedgedriver.exe"
driver = webdriver.Edge(path)
driver.get("https://google.com")
print(driver.title)"
My web driver version is 88.0.705.50 (Official build) (64-bit)
I use selenium 3 and I am getting this error while running the code. Also it is opening "data:," for a few seconds then opening Google. Lastly the browser doesn't stay open.

Declare path on a separate line from the import statement
Use raw string in path or double escapes
Code:
from selenium import webdriver
path = r"C:\Users\Home\Documents\Python37-32\Scripts\Code\msedgedriver.exe"
driver = webdriver.Edge(path)
driver.get("https://google.com")
print(driver.title)

What error do you get? It's the default behavior that the browser opens with data:,, then it will direct to the website you want. The browser doesn't stay opened may because the error breaks it.
You can refer to the following steps to automate Edge in python selenium:
Make sure the WebDriver version is the same as the Edge version.
Install the MS Edge Selenium tools using command below:
pip install msedge-selenium-tools selenium==3.141
Sample code:
from msedge.selenium_tools import Edge, EdgeOptions
options = EdgeOptions()
options.use_chromium = True
driver = Edge(executable_path = r"C:\Users\Home\Documents\Python37-32\Scripts\Code\msedgedriver.exe", options = options)
driver.get("https://google.com")
print(driver.title)

How to initiate a Chromium based Vivaldi browser session using Selenium and Python

I am trying to use the vivaldi browser with Selenium. It is a chromium browser that runs very similar to chrome. I have Selenium working with Firefox (geckodriver), and Google Chrome(chromedriver), but I can't seem to find a way with Vivaldi. Any help would be appreciated.

If the vivaldi binary by default is located at C:\Users\levir\AppData\Local\Vivaldi\Application\vivaldi.exe you can use the following solution:
from selenium import webdriver
from selenium.webdriver.chrome.options import Options
options = Options()
options.add_argument("start-maximized")
options.binary_location=r'C:\Users\levir\AppData\Local\Vivaldi\Application\vivaldi.exe'
driver = webdriver.Chrome(executable_path=r'C:\path\to\chromedriver.exe', options=options)
driver.get('http://google.com/')

For future reference:
to make Vivaldi work with selenium you need to make sure of three things :
The correct version of ChromeDriver
Set selenium's driver to use Vivaldi's binary via webdriver.ChromeOptions()
Make sure you're getting the correct url (don't forget "https://")
All of the above is explained step by step with screenshots in this blog post

The key executable_path will be deprecated in the upcoming releases of Selenium.
This post has the solution. I'm posting a copy of said solution with the path to Vivaldi, where the username is fetched by the script so you don't have to hard code it.
from selenium import webdriver
from selenium.webdriver.chrome.service import Service
import os
current_user = os.getlogin()
s = Service(rf"C:\Users\{current_user}\AppData\Local\Vivaldi\Application\vivaldi.exe")
driver = webdriver.Chrome(service=s)
driver.get("http://duckduckgo.com") # or your website of choice

You can use ChromeOptions and supply binary.
from selenium.webdriver.chrome.options import Options
opt = Options()
opt.binary_location = chromium_path//path to chromium binary
driver = webdriver.Chrome(options=opt, executable_path="path_to_chromedriver")

set "user-data-dir" in selenium python for chrome driver in Ubuntu [duplicate]

I'd like to launch Chrome with its default profile using Python's webdriver so that cookies and site preferences persist across sessions.
How can I do that?

This is what finally got it working for me.
from selenium import webdriver
options = webdriver.ChromeOptions()
options.add_argument("user-data-dir=C:\\Path") #Path to your chrome profile
w = webdriver.Chrome(executable_path="C:\\Users\\chromedriver.exe", chrome_options=options)
To find path to your chrome profile data you need to type chrome://version/ into address bar . For ex. mine is displayed as C:\Users\pc\AppData\Local\Google\Chrome\User Data\Default, to use it in the script I had to exclude \Default\ so we end up with only C:\Users\pc\AppData\Local\Google\Chrome\User Data.
Also if you want to have separate profile just for selenium: replace the path with any other path and if it doesn't exist on start up chrome will create new profile and directory for it.

This solved my problem. (remove Default at the end)
from selenium import webdriver
options = webdriver.ChromeOptions()
options.add_argument("--user-data-dir=/home/username/.config/google-chrome")
cls.driver = webdriver.Chrome(options=options,
executable_path="./../ext/chromedriver")
Chrome_Options ist deprecated. Use options instead

I solved my problem with answer of "Yoannes Geissler".
In my case My profile was named "Profile 2"
My Code :
options = webdriver.ChromeOptions()
options.add_argument('--user-data-dir=C:/Users/GOD/AppData/Local/Google/Chrome/User Data')
options.add_argument('--profile-directory=Profile 2')
wd = webdriver.Chrome(options=options)
The below line solved my problem:
options.add_argument('--profile-directory=Profile 2')

Just to share what worked for me. Using default's profile was complicated, chrome keeps crashing.
from pathlib import Path
from selenium import webdriver
driver_path = Path("{}/driver/chromedriver75.exe".format(PATH_TO_FOLDER))
user_data_dir = Path("{}/driver/User Data".format(PATH_TO_FOLDER))
options = webdriver.ChromeOptions()
# TELL WHERE IS THE DATA DIR
options.add_argument("--user-data-dir={}".format(user_data_dir))
# USE THIS IF YOU NEED TO HAVE MULTIPLE PROFILES
options.add_argument('--profile-directory=Default')
driver = webdriver.Chrome(executable_path=driver_path, options=options)
driver.get("https://google.com/")
By doing this Chrome will create the folder User Data and keep all the data in it where I want and it's easy to just move your project to another machine.

This answer is pretty simple and self-explained.
from selenium import webdriver
from selenium.webdriver.chrome.options import Options
exec_path_chrome = "path/to/Google Chrome" #Do not use this path that is extracted from "chrome://version/"
exec_path_driver = "path/to/chromedriver"
ch_options = Options() #Chrome Options
ch_options.add_argument("user-data-dir = /path/to/Chrome Profile") #Extract this path from "chrome://version/"
driver = webdriver.Chrome(executable_path = exec_path_driver, options = ch_options) #Chrome_Options is deprecated. So we use options instead.
driver.get("https://stackoverflow.com/a/57894065/4061346")
As #MadRabbit said type chrome://version/ into the address bar to find the path to your chrome profile data.
It appears like this in Windows C:\Users\pc\AppData\Local\Google\Chrome\User Data\Default
It appears like this in Mac /Users/user/Library/Application Support/Google/Chrome/Default
So all you have to do is to erase the last portion Default from the profile path.
Note: Make sure you don't run more than one session at the same time to avoid problems.

This is what I did.
import chromedriver_binary
chrome_options = Options()
chrome_options.add_experimental_option("detach", True)
chrome_options.add_argument(r"--user-data-dir=User Data Directory")
chrome_options.add_argument(r"--profile-directory=Profile name")
chrome_options.add_experimental_option("useAutomationExtension", False)
chrome_options.add_experimental_option("excludeSwitches",["enable
logging"])
chrome_options.add_experimental_option("excludeSwitches", ["enable
automation"])
chrome_options.add_argument("start-maximized")
self.driver = webdriver.Chrome(chrome_options=chrome_options)
self.wait = WebDriverWait(self.driver, 20)
Here we do not need to give the chrome driver path.

Getting Chrome to launch via Selenium

I am having issues getting an instance of a Chrome browser from selenium in python. I'm using Windows 8. I have downloaded the chromedriver binary and added it to my path but I get the following error in Python:
selenium.common.exceptions.WebDriverException: Message: 'ChromeDriver executable needs to be available in the path.
This error occurs for the following line:
driver = webdriver.Chrome(executable_path='path\to\chromedriver_win32_2.0')

Two ways to set it, you somehow mixed up.
Put the chromedriver.exe's path into PATH (on Windows), so your PATH setting is correct, but you need to call the default constructor.
driver = webdriver.Chrome()
Specify the path in webdriver.Chrome(executable_path='some path'). Here you need the full path to the executable, not the directory.
webdriver.Chrome(executable_path=r'C:\Users\HaranKumar\Downloads\chromedriver_win32_2.0\chromedriver.exe')
Choose either one you want.

Assuming that your path is correct, make sure that you include the chromedriver itself: chromedriver.exe

I used the following and it worked! Thanks!
driver = webdriver.Chrome(executable_path=r'C:\chromedriver.exe')
#put your own path between the ''

Even if you have chromedriver.exe in the PATH, its necessary to have chromedriver.exe in the folder where your executable scripts are present(atleast so is the case when it comes to python scripts)

for python(selenium) you will need:
from selenium import webdriver
from selenium.webdriver import Chrome
from selenium.webdriver.chrome.options import Options
then put your chromedriver.exe path in. the "r" is just to prevent it from detecting the \ and causing errors in python
PATH = r"C:\Program Files (x86)\chromedriver.exe"
driver = webdriver.Chrome(PATH)
options = webdriver.ChromeOptions()
you can now order the driver to get websites
driver.get('http://www.google.com')

Update 2021
For Python
I got Selenium to open my default Chrome browser with my profile using this:
options.add_argument("--user-data-dir=C:\\Users\\Sams\\AppData\\Local\\Google\\Chrome\\User Data")
options.add_argument('--profile-directory=Default')
Go to: chrome://version/
Look for your "Profile Path"
profile path image
Copy your Profile Path and replace "options.add_argument("--user-data-dir={YOUR PROFILE PATH}")"
The second argument may also look different. Mine so happens to be "Default". For other it may be "Profile 1" or "Profile X" X being an incrementing number.
Close all your Chrome browsers before running. Because the Chrome Driver cannot run an automated browser alongside the rest of your other tabs.
Here is my entire Selenium Config. Hopefully it helps someone.
from selenium import webdriver
from selenium.webdriver.chrome.options import Options
from selenium.webdriver.common.by import By
from selenium.webdriver.support import expected_conditions as EC
from selenium.webdriver.support.ui import WebDriverWait
from webdriver_manager.chrome import ChromeDriverManager
from selenium.webdriver.remote.webdriver import WebDriver
options = Options()
options.add_argument("--window-size=1920,1080")
options.add_argument("--log-level=3")
options.add_experimental_option('excludeSwitches', ['enable-logging'])
# The 2 arguments below will use your main browser.
options.add_argument("--user-data-dir=C:\\Users\\Sams\\AppData\\Local\\Google\\Chrome\\User Data") # profile path (C)
options.add_argument('--profile-directory=Default')
options.headless = False # To show Chrome or not to show?
PATH = (r"C:\Users\Sams\AppData\Local\Programs\Python\Python37-32\Lib\site-packages\selenium\webdriver\chrome\chromedriver.exe")
CHROMEDRIVER_PATH = PATH
driver = webdriver.Chrome(CHROMEDRIVER_PATH, options=options)

I recently ran into this error and I found three main solutions for this chromedriver not in path error
download a library that does it - webdriver_manager or chromedriver_autoinstaller both work
add it to path in your program
add chromedriver executable to your system PATH

Update 2016
The following solution works for me, with WebDriver 3.0.1, Chrome Driver 2.25.426923, Window 7
System.setProperty("webdriver.chrome.driver","D:\\workspace\\chromedriver.exe");
WebDriver driver;
driver = new ChromeDriver();
*Note:
Chrome Driver
