Hi, I have the same issue:
selenium.common.exceptions.WebDriverException: Message: unknown error: Chrome failed to start: exited abnormally

Can you help me please?
              
Hello, I have the same error. selenium.common.exceptions.WebDriverException: Message: unknown error: Chrome failed to start: exited abnormally
  (unknown error: DevToolsActivePort file doesn't exist)
  (The process started from chrome location / usr / bin / chromium-browser is no longer running, so ChromeDriver is assuming that Chrome has crashed.)
  (Driver info: chromedriver = 2.42.591071 (0b695ff80972cc1a65a5cd643186d2ae582cd4ac), platform = Linux 4.4.0-1100-aws x86_64)
What is the reason for this?
              
Our system does not support Chrome by default, it's something that we have to switch on for you.  I've done that now, and as a next step, you'll need to upgrade Selenium for your account -- for example, if you're using Python 3.7, run this in Bash:
pip3.7 install --user --upgrade selenium
...and then you can run Selenium with Chrome using code like this:
chrome_options = webdriver.ChromeOptions()
chrome_options.add_argument("--headless")
chrome_options.add_argument("--disable-gpu")
browser = webdriver.Chrome(options=chrome_options)
try:
    browser.get("https://www.google.com")
    print("Page title was '{}'".format(browser.title))
finally:
    browser.quit()
              
I believe I've got a similar problem....
Here's my error:  (The process started from chrome location /usr/bin/chromium-browser is no longer running, so ChromeDriver is assuming that Chrome has crashed.)
  (Driver info: chromedriver=2.42.591071 (0b695ff80972cc1a65a5cd643186d2ae582cd4ac),platform=Linux 4.4.0-1100-aws x86_64)
              
I'm a new user, and intend to use  Selenium and ChromeDriver. Based on the above, can you do the same for my account.
Thanks, ds4573
              
please enable chrome for me. thank you
I have the following error while running my application

Sure! I've switched on the new virtualization system for you, so if you follow the steps from my previous post then that will get Chrome working for you.
Wow! You guys have a lightning fast support, I'm super positively impressed! Thanks a lot
              
@Tsurubaso -- what problems are you seeing?  The feature is switched on for your account, so as long as you've upgraded Selenium (see this post) it should all work fine.
@yall -- no problem!  Glad to help.
              
Your account will also need its system image to be changed in order to support Chromedriver.  Your files and data will be unchanged, but it will change the point releases of Python (eg. 3.7.0 to 3.7.5), which might break any virtualenvs you have -- and if you're not using virtualenvs, the pre-installed Python modules will be upgraded so that might break any code you have that relies on the old installed versions.
If you're happy for us to switch you over despite that, then let us know.

Hi, i have a question, i am gonna use aroud 100-150 processes with multiprocessing,1 process include new initialization with webdriver. It means i'll have 150 processes with 150 different opened windows(webdrivers). How can i use this script on your servers and is it posible? And another question if it would be posible so i'll need to send 150 requests(driver.get("some site")) to only 1 site,how i understand i'll need to use proxies,right? And which driver can u recommended me, firefox or chrome,which work better on your servers with proxies etc. Thanks in advance.
              
A couple things to look out for:
if you are free user, you can only access our whitelisted sites over http/https.
depending on how memory intensive this is, it may run up against memory limits and be killed
see this, the standard recommended solution, which is firefox, but also see this which will require us to switch it on for you, which is Chromium
              
You can see the features that each account has on your account page and you can also use the "Customise your plan" to choose a specific set of features. The features you need will depend on your code.
Each process can use 3G of memory and there is no real way to measure your use except by experimenting to see when your processes get killed. You are much more likely to run into our process limit, which is 128 processes per user per server.

This is the code is in browser.py file
              
@yonataliasu13 we have turned on that virtualization for you- any new consoles you start will be able to run chrome.
@dewey you already have that virtualization turned on. I see that you pasted a lot of code a couple replies up. Could you try doing this, and using this simple code instead to see if it runs?
              
Hello! I have such error : 
    unknown error: Chrome failed to start: crashed
      (unknown error: DevToolsActMessageivePort file doesn't exist)
      (The process started from chrome location /usr/bin/chromium-browser is no longer running, so ChromeDriver is assuming that Chrome has crashed.)

5.4.0-1020-aws x86_64)
I think that possibly chrome was not closed in the previous running. Can you check it for me, please? And how I can check it and fix? Chrome is available for my account
              
At the moment we have an old version of firefox available on the system, and it misbehaves. That's why we recommend chrome and suggest the activation of experimental features required to run it (it's already done for you). As far as I know, nothing (apart from the general flakiness of the installed firefox) prevents you from running both.
              
Hi, I restarted all consoles, verified selenium was upgraded to the latest, and tried the sample code in the post from April 13, 2020 to verify but am still getting the classic error when trying to run chromedriver:
"(unknown error: DevToolsActivePort file doesn't exist)

Is it possible my account wasn't enabled?
              
@jhollier It is enabled for you. How do you configure your webdriver?
That examle code works:
chrome_options = webdriver.ChromeOptions()
chrome_options.add_argument("--headless")
chrome_options.add_argument("--disable-gpu")
browser = webdriver.Chrome(options=chrome_options)
    browser.get("https://www.google.com")
    print("Page title was '{}'".format(browser.title))
finally:
    browser.quit()
You should also upgrade selenium with something like:
pip3.7 install --user --upgrade selenium
              
I have received this error while attempting to use Selenium and chromedriver, could my account by changed for the new virtualization as well?:

I have enabled the following Selenium Webdriver settings for chromedriver:
options = ChromeOptions()
options.add_argument("--disable-gpu")
options.add_argument("--headless")
Thank you for your help.

Hi @rashidanwar0146. We're currently in the process of enabling the new virtualization system for all accounts on PythonAnywhere, which unfortunately may take a week or two to complete. We'll let you know when that has been done for your account; I've made a note to make sure that you're in one of the next batches to be moved over to it.
              
@ageronimo -- you need to update your system image to the most recent one first: https://help.pythonanywhere.com/pages/ChangingSystemImage/.
@reza16, @fabio8178 -- did you update Selenium as advised above?
For example, if you're using Python 3.7, run this in Bash:
pip3.7 install --user --upgrade selenium
...and then you can run Selenium with Chrome using code like this:
chrome_options = webdriver.ChromeOptions()
chrome_options.add_argument("--headless")
chrome_options.add_argument("--disable-gpu")
browser = webdriver.Chrome(options=chrome_options)
try:
    browser.get("https://www.google.com")
    print("Page title was '{}'".format(browser.title))
finally:
    browser.quit()
              
Hi.  I'm trying to get selenium to work, and can't seem to figure it out.  Totally novice question, but when I run a python script that calls chrome, I get this error: 
WebDriverException: Message: 'chromedriver' executable needs to be in PATH. Please see https://sites.google.com/a/chromium.org/chromedriver/home
I can't figure out a) what version of chromedriver I need, and b) where to put it?  I tried putting it where the python file is and a few others areas, and nothing seems to work.  Any ideas?
              
I'm a new user, and intend to use Selenium and ChromeDriver. Based on the above, can you do the same for my account and enable chrome for me
Thanks!
              
I am running glastonury and all packages are installed. when i try the example above I get the following error. Any ideas?

Hi Giles,




    

Can you please turn chrome on for my account. I've already subscribed to the Hacker account. I can't seem to run my .ipynb scripts.
Thank you very much!
Respectfully,
              
Hi Glenn,
Is there a workaround on how to read .xlsx file in .py files. my chromedriver works perfectly fine when running my script in .py but whenever I try to do a pd.read_excel(), it returns an empty dataframe. I already tried adding engine='openpyxl', but the error still persists.
I apologize this post is unrelated to this thread.
Respectfully yours,
              
That doesn't necessarily mean that there is actually anything in the file. Have you checked that the file that you're reading actually has anything in it to import? Also, make sure that you're reading the file that you think you're reading: https://help.pythonanywhere.com/pages/NoSuchFileOrDirectory/
              
Hi, can you enable chrome for me? I am having an issue:
selenium.common.exceptions.WebDriverException: Message: unknown error: Chrome failed to start: crashed.
  (unknown error: DevToolsActivePort file doesn't exist)
  (The process started from chrome location /usr/bin/chromium-browser is no longer running, so ChromeDriver is assuming that Chrome has crashed.)
              
Here's what I've been getting, and nothing from the forums seems to work:

That's the error I got with the minimal example. 
Here's my code
            #Setting up Chromium Settings
            chrome_options = webdriver.ChromeOptions()
            chrome_options.add_argument("--headless")    

            chrome_options.add_argument("--disable-gpu")   
        driver=webdriver.Chrome(options=chrome_options)
          driver.get("https://www.google.com")
          print("Page title was '{}'".format(driver.title))
        finally:
          driver.quit()
Maybe I'm having the wrong package? Is there a specific package I would need for chromium browser?
              
I am having the same error:

What should be done?
              
In fact, it is very time sensitive and I'm facing an issue with the driver despite best attempts:

Hello, please enable ChromeDriver for me too. Thank you.
I have got this error message:

  (The process started from chrome location /usr/bin/chromium is no longer running, so ChromeDriver is assuming that Chrome has crashed.)
What's happening here, something to enable manually?
I'm on latest available image (glastonbury) and can't run the sample code.

Sample code:
 from selenium import webdriver
    chrome_options = webdriver.ChromeOptions()
    chrome_options.add_argument("--no-sandbox")
    chrome_options.add_argument("--headless")
    chrome_options.add_argument("--disable-gpu")

        browser.get("https://www.google.com")
        print("Page title was '{}'".format(browser.title))
    finally:
        browser.quit()
Selenium version(also tried latest):
pip3 list | grep selenium
selenium                         3.141.0
Because python-anywhere limits the amount of processes you can have running at once, if you are scraping numerous sites and using driver.quit() or closing chrome through a bash command, python (as the parent process) will retain some defunct processes for every chrome process that was open.  If you do this enough time you  will have too high a process count and chromedriver will refuse to open.  
Running the 2 lines of code will ignore the default setting of retaining child processes until the parent is closed.  However, if for some reason you need to retain these defunct processes, then this will cause other problems for you.  It works for me, hope it works for you.
              
I'm facing similar issue
