i'm having this error whenever i run selenim with Chrome:
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.)

We have a new, experimental way of sandboxing users that should allow you to use a more recent version of Chrome. Let us know if you'd like us to enable it for your account.
yes i would like to , thanks
Ok. I have enabled it for your account.
Hi, I have the same issue: 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.)

Ah- okay, I have turned on that virtualization for you. You will have to restart your console/webapps etc for the change to take effect.
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:
glenn

PythonAnywhere staff

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, can you enable chrome for free versions for testing? thank you
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
No problem @zaheer, @outsidedog and @ds4573, I have enabled it for your account.
Hi am new as well can someone teach me how to install?
Could you give more details about what you're trying to do, and what problems you're having?
please enable chrome for me. thank you I have the following error while running my application WebDriverException at /new_search 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.)
OK -- I've switched that on, so if you follow the steps from my previous post then that will get Chrome working for you.
i followed previous post steps but still showing the same error. (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.)
Sorry, it looks like the setting was not actually applied. I have applied it now so it should work. Bear in mind, that if you're running the code in a console, you will need to start a new console for it to be applied and if you're running it in a web app, you will need to reload the web app.
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, ifmeonline
OK -- I've switched that on, so if you follow the steps from my previous post then that will get Chrome working for you.

Hi, can you help me switch to the most recent system? I would like to use Selenium + ChromeDriver too. Thank you.
I'm a new user, and intend to use Selenium and ChromeDriver. Please activate me this
@theansweryang, @darerror Sure, I've switched that on for both of you, so if you follow the steps from my previous post then that will get Chrome working for you.
so. i have done this work (previous steps), but i still have unknown error: Chrome failed to start: crashed (unknown error: unable to discover open pages) (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)
Now i have: Message: session not created from tab crashed
Are you getting emails about processes in your account running of of memory and crashing?
can we use Selenium and ChromeDriver with free acount? If it is possible, please activate me this, else please tell me which paid account I should get.
It is possible, but keep in mind that with a free account, you can only access a whitelist of external sites that are public apis. So it may not work for your use case. If you still want to do that let us know and we will set you up.
Hello, you can also turn on the ChromeDriver for me.

Ok, @Shrik558 and @MutFild, I have enabled it for your accounts.
Hello, could you please turn on this thing for me? Thanks.
Ok. I have enabled it for your account.

OK -- 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.
Hi, I was wondering if you could enable this feature for me as well. I'm having the same issues here.
Sure, I've turned that on for you.
Can I please have this turned on for me as well? I'm currently a free user, and testing Selenium + Chrome with the whitelist websites for now. Will move over to a paid account once I can verify that my code works.
Sure, we've turned that on for you.
Could you please turn the new virtualization on for me as well? so I can be able to run Chrome driver headless. Thank you very much
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.
I tried yesterday, either home or here, is Selenium have a problem???? Is there a tutorial?? Is my security blocking me??? how to check that???
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
Could you please turn the new virtualization on for me as well? so I can be able to run Chrome driver headless. Thank you very much
Your account is still on an old system image. To make it work we would have to update your system image, too. Switching to a new system image may break your code that was working on your old image. You will also need to rebuild any virtual environments you have created.
Ok sir, I have backed up my all resources it's ready to update. You can take action.
No problem. That's done. New consoles will use the new system and your web app will use it once it has been reloaded.
Hi!, please turn on the ChromeDriver for me.Thanks!
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.
Hello, I also wanted to have the new virtualization on for me, I am trying to use Selenium to automate a task. Thanks!
Sure, no problem -- that's done now, and new consoles will be using it. If you follow the steps from my previous post then that will get Chrome working for you.
Hi!, please turn on the ChromeDriver for me.Thanks!
Hi! I'm ready. Please turn on ChromeDriver. Thanks!
Hi, please turn on the ChromeDriver for me.Thanks!
No problem, @archproug and @blackhat0, I have enabled it for your accounts.
I upgraded to payed account. can you turn on the ChromeDriver for me to use selenium? Thank you.
Its enabled for you, @academicpost
HI! I have a free account. Could chrome be enabled for my account too? Thanks!
Sure, no problem -- that's done now, and new consoles will be using it. If you follow the steps from my previous post then that will get Chrome working for you. It's worth noting, though, that from a free account you are still limited to the sites on our whitelist.
Я новый пользователь и собираюсь использовать Selenium и ChromeDriver. Исходя из вышеизложенного, можете ли вы подключить их для моей учетной записи. Спасибо 0310sawbuy0310
0310sawbuy0310 it's done for you.
выдает вот такую ошибку, с чем это может быть связано?
File "/home/0310sawbuy0310/.local/lib/python3.8/site-packages/selenium/webdriver/common/service.py", line 86, in start raise WebDriverException( selenium.common.exceptions.WebDriverException: Message: 'chromedriver' executable may have wrong permissions. Please see https://sites.google.com/a/chromiu m.org/chromedriver/home
You appear to be trying to use a chromedriver executable that is not the one that we have installed and you have not made it executable. Chromedriver is quite sensitive to versioning, so I would suggest not specifying the chromedriver in your code and use the one that is installed by default.
Hi!, please turn on the ChromeDriver for me. Thanks! I want to test just for now, then I will upgrade my account
Sure, no problem -- that's done now, and new consoles will be using it. If you follow the steps from my previous post then that will get Chrome working for you. It's worth noting, though, that from a free account you are still limited to the sites on our whitelist.
I am also stuck on getting the chromedriver up and running. Mind activating mine account too? I'm currently testing and would like to use selenium with chromedriver to scrape Instagram. Is that possible?
hi ! please the same problem here please can you turn on the ChromeDriver for me. thanks in advance.
@Gissa and @kumarraj123, I have enabled it for your accounts.
which chrome version is installed here can u tell me?
Chromium 78.0.3904.70 Built on Ubuntu , running on Ubuntu 16.04
Hello, could you switch on this Chrome support for me?
Thanks!
No problem. I have enabled it for your account.
Hi, is it possible to activate Chrome support for me too? Thanks!
It's done for you.
Hi, could I have it enabled for me aswell? Thanks!
Sure, no problem -- that's done now, and new consoles will be using it. If you follow the steps from my previous post then that will get Chrome working for you. It's worth noting, though, that from a free account you are still limited to the sites on our whitelist.

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:
@conrad Ок,thanks. And what paid plan are u recommended me for my tasks? And how many memory limit maximum can be use for 1 task so my process won't be kill? And last question,can i mesure how many memory used for only 1 task?
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.
Hi, I am trying to use selenium with chrome driver but it's giving me an error. I suspect it's the chrome not being enabled. Can you enable chrome for me?

can you enable chrome for me please
Sorry how do i enable chrome?
@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
@MrGorsky Are you sure that it is running headless?
It is running not in headless mode. I tried to use it in this way (not headless), and my script worked, but later browser crashed and I saw this error. Can I use it without headless?
You can use it in non-headless mode, though it will run more slowly. How are you running the script -- is it from a console, or inside a website's code, or in a scheduled task?
I use it in scheduled tasks. I killed all running tasks in tab "Tasks", and now chrome works well. Thank you for your concern :)
Glad to hear you got it working!
Hello! I want to run one of my scripts in sheduled tasks using selenuim+chrome and other script using selenium+firefox? Is is possible to activate chromedriver and geckodriver both to my account? Now chrome is available for me.
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, can I also have Chrome enabled?
ok sure, we have enabled that for you.
Hi, can I also have Chrome enabled please? Thanks.
No problem, it's enabled for you @zparkar.
@pafk Hey, can you activate chrome browser in my account please? Thanks a lot!
No problem. I have activated it for your account.
Hey, can you activate chrome browser in my account please? Thanks a lot!
Sure, no problem -- that's done now, and new consoles will be using it. If you follow the steps from my previous post then that will get Chrome working for you.
Hi, can I please have Chrome activated in my account too?
Sure, @henrydh, it's done for you.
Hi, can I please have Chrome activated in my account too? :) :) :)
@freddy57 It's done for you
Hey, could you please configure my account to be able to use Chrome too?
Appreciate it.
It looks like it is already enabled for your account.

Sure, no problem -- that's done now, and new consoles will be using it. If you follow the steps from my previous post then that will get Chrome working for you.
Please configure my account to be able to use Chrome with selenium, please
Hello!! I would like to run chrome webdriver too! Can it be switched on for me?
Hi, can you please enable my account to work with Chrome as well? Thanks!
@renatonm007 @jhollier It's done for both of you
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) (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 5.4.0-1020-aws x86_64)"
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)
try:
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
Interestingly, everything works great now with no changes. Anyway, thanks for the assistance :)
Thanks for letting us know!
can you please enable my account to work with chrome as well?
@devinjcooley -- I see you asked for this in several threads, already replied in another one.
I have received this error while attempting to use Selenium and chromedriver, could my account by changed for the new virtualization as well?:
Error Message: unknown error: Chrome failed to start: exited abnormally

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.

Sure, no problem -- see my previous post for the next steps.
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!
No problem. I have updated your account.
I had a Selenium / chromedriver setup working on my account as you have activated it in the past. Yesterday I have upgraded my account and now receive the same error message as the previous users. Could you please check if upgrading the account has somehow disabled chrome? Thank you!
No, the setting is still enabled on your account.
Can you enable for me?
Since our most recent deploy, we have to pause adding the feature for a while until we can switch everyone across.

Thank you so much for all 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.
@rashidanwar0146 that's done for you now; see my previous post for the next steps.
I'm a new user, and intend to use Selenium and ChromeDriver. Please activate me this
@bory -- I already replied to you in the other thread. If you still have problems, contact support@pythonanywhere.com providing us with more details.
I'm beginner, please enable chromedriver on my account
I'm beginner, please enable chromedriver on my account as well.
Hello, please enable ChromeDriver for me too. Thank you.
@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()
@pafk I've updated system image to fishnchips and everything's working now. thank you!
@ageronimo -- excellent, thanks for confirming!
@giles @pafk Hello, can you enable please Chromedriver for me? Thanks!
It is already enabled by default for all accounts
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?
@tonysmall75 -- we already provide chromedriver executable with version matching installed Chrome, which is on PATH, so you don't need to specify that.
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!
VikP
It's enabled for all new accounts.
Hi there, can you activate my chrome as well please?
It's activated for all accounts now.
I am running glastonury and all packages are installed. when i try the example above I get the following error. Any ideas?

How does your code look like? From the traceback, it looks like it's not identical to the one above.
Here is the code. Line 27 is browser = webdriver....................

return result
It works now!! Not sure what changed but thanks.

That looks like it should work fine. Have you tried running that in a newly created console?

Don't pass 'chromedriver' as the first argument when you;re creating the webdriver. The first argument to webdriver.Chrome is the path to chromedriver, which is already on the path and, if you specify it incorrectly, like you did, then it will not work.
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,
Jaca
Chrome is already enabled for your accounts, but it will not work well in notebooks.
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,
Jaca
Have you checked that there is actually data in the Excel file that you're trying to read with read_excel?
Yes Glenn, I downloaded it from my directories.
Yes Glenn, I downloaded it from my directory.
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 I also intend to use Selenium python and ChromeDriver. Based on the above, can you do the same for my account and enable chrome/ change needed settings for me? Thanks!
In fact, it is very time sensitive and I'm facing an issue with the driver despite best attempts:

The most likely cause of that is that the page changed in some way that is causing Chrome to crash.
Ignore this post, just realized I already have this.

Where are you running that code -- is it in a console, a website's code, in a notebook, or an always-on or scheduled task?
Hi giles,
I'm running it from console (ssh).
Ah, that explains it -- Selenium unfortunately doesn't work in SSH or in Jupyter notebooks right now. We're planning to change that in the future, but for now you'll need to run it in one of our in-browser consoles, in a scheduled or always-on task, or inside a website's code.
Thank you for information. From browser console it works.
Excellent, thanks for confirming!
Hey support, I got the same error too, please enable chromedriver or virtualization (whatever it takes) for my account as well plz, thank you
It's already enabled for all accounts. Which error exactly do you have? Where are you running your selenium code on PythonAnywhere? Also -- is the sample code from this help page working for you?
I fixed my issue by adding:
import signal
signal.signal(signal.SIGCHLD, signal.SIG_IGN)
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.
Glad to hear that you made it work!
can I please also have the chrome driver enabled for me? I need it to run selenium tests. Thanks.
It is already enabled for all accounts.

@NikNak92 We added some capacity to our task infrastructure. Let us know if it is not fixed during your next task run.
@fjl perfekt the program is now also working in the task. Thank you.
Can you also turn on chromedriver for me?
It's available for everyone now. If something is not working for you, see this help page.
hi, can you enable chrome for me ?
@mzr2q It's available for everyone now. If something is not working for you, see this help page.
Can I please have this turned on for me as well? I'm currently a free user, and testing Selenium + Chrome with the whitelist websites for now.

Make sure you follow the set up mentioned in this help page and not start multiple browsers at a time.
I have the same setup mentioned in the help page, what do you mean by not starting multiple browsers at a time.
This is the issue that is happening :
