Can't run multiple instances

[Mikayel0]

Can not run more than one browser

import undetected_chromedriver as uc
import os
from concurrent import futures

def browser(thread):
    uc.Chrome()
    print(thread)
    input()

def main():
    os.system('cls')
    threads = input("How much threads you want: ")
    with futures.ThreadPoolExecutor() as executor: 
        future_test_results = [ executor.submit(browser, i)  
        for i in range(int(threads)) ]
        for future_test_result in future_test_results: 
            try:        
                test_result = future_test_result.result()          
            except Exception as exc:
                print('thread generated an exception: {:0}'.format(exc))

if __name__ == "__main__":
    main()

When second browser is opening

FileExistsError: [WinError 183] Cannot create a file when that file already exists:

Have the same issue. I use this configuration: def init_driver(): chrome_options = uc.ChromeOptions() chrome_options.add_argument("--incognito") chrome_options.add_argument('--headless') chrome_options.add_argument("--log-level=3") chrome_options.add_argument("--start-maximized") driver = uc.Chrome(options=chrome_options, use_subprocess=True) driver.wait = WebDriverWait(driver, 2) return driver

driver = init_driver()

When i use only 1 browser is ok. But when i try to open another

driver_2_example = init_driver()

i get this exception:

  File "C:\Users\Dragur\AppData\Local\Programs\Python\Python39\lib\site-packages\undetected_chromedriver\__init__.py", line 374, in __init__
    if self.patcher.version_main < 108:
TypeError: '<' not supported between instances of 'NoneType' and 'int'

This happens since V110 of Chrome I'm using

undetected-chromedriver   3.4.4
selenium                  4.8.0

(Yes i'm the same who posted the --headless issue) sorry to bother you so much, I really appreciate your job @ultrafunkamsterdam

[ultrafunkamsterdam]

i really shouldnt be doing this.... here we go:

pip install -U https://github.com/ultrafunkamsterdam/undetected-chromedriver@fix-multiple-instance

please check if it is really installed, or just run this twice. report back appreciated..

When i tried to start few browsers they started well, after first time i was getting same exception

[tomslarkin]

I have the same issue, any solution would be appreciated!

[tomslarkin]

I may have figured out a workaround just now. in the "patcher.py" file I added "import secrets" at the top and then changed: from: prefix = 'undetected'

to: prefix = secrets.token_hex(8)

I figured this out by looking back at version 3.2.1 of undetected-chromedriver, and that's how it was working before.

[vsuyvkpzica46088]

do this: chrome_driver = uc.Chrome(version_main=CHROME_VERSION, options=chrome_options)

will fix the issue

[labodj]

No, it doesn't

Anyway... I just retested the code updated to 57a2bd3f436832ffe8b127efa1d358a64f32be6f and it seems to be working again using chrome 110.

You can try it like so

python -m pip uninstall undetected-chromedriver
python -m pip install git+https://github.com/ultrafunkamsterdam/undetected-chromedriver@fix-multiple-instance
python -m pip install --upgrade selenium

Thaaaaaaaank you. it's worked for me.

[antooro]

My two browsers are opening but I see this issue: Only the first one is making the requests and what i have programmed. The second one stays only in the initial chrome screen.

I'm using different profiles in each driver!!!! So i set --profile-directory and --user-data-dir

selenium.common.exceptions.WebDriverException: Message: unknown error: cannot connect to chrome at 127.0.0.1:51381

FIXED=

Split your profile data under diferent folders, dont use same one, one per eaceh

Everything is updated

[MaverickAlonso]

Hi antooro, did you fix the issue mentioned? are you able to manage every single instance correctly?

[PatrickVdWillik]

I tried running this branch with Chrome 111 and Incapsula will trip on it. When I switch back to the regular version it works just fine.

[simplexx]

I noticed this issue as well. Latest changes added prevent running multiple instances of the driver at the same time because the naming was changed from random 8 numbers to fixed string "undetected". The result of this is that only 1 file can exist and an error is thrown if a second file is created. I did not dig further into the code, but do we even need multiple executable at all? If not then it looks like detection if the executable already exists is broken, which would make this a bug.

[ultrafunkamsterdam]

Instead of making it yourselves hard, mind you there is a branch for this ....

[simplexx]

EDIT: Please ignore below. Seems like I f'ed up something during testing (probably used unmodified driver in the test by mistake). Currently trying to run it on my server (ARM architecture on AWS). But it seems like ARM is not supported at the moment. Driver won't start throwing a wrong executable type error :(

Now I am sure it's a bug, because it happened on my win 10 machine, but when i tried it on ubuntu 20 on the server there was no such issue. So windows (10?) specific bug. In both cases I run selenium headless btw. In any case nice project! Thanks for maintaining it!

[simplexx]

So I have created a new server with a supported architecture, and these are the results: New branch: Does not work, throws the following error: /usr/bin/chromium-browser: 12: xdg-settings: not found /usr/bin/chromium-browser: 12: xdg-settings: not found [9126:9300:0326/154912.698727:ERROR:object_proxy.cc(623)] Failed to call method: org.freedesktop.DBus.ListActivatableNames: object_path= /org/freedesktop/DBus: org.freedesktop.DBus.Error.AccessDenied: An AppArmor policy prevents this sender from sending this message to this recipient; type="method_call", sender=":1.43" (uid=1000 pid=9126 comm="/snap/chromium/2406/usr/lib/chromium-browser/chrom" label="snap.chromium.chromium (enforce)") interface="org.freedesktop.DBus" member="ListActivatableNames" error name="(unset)" requested_reply="0" destination="org.freedesktop.DBus" (bus) [9126:9126:0326/154912.705819:ERROR:process_singleton_posix.cc(334)] Failed to create /home/ubuntu/.local/share/undetected_chromedriver/tmpwymqvrgk/SingletonLock: Permission denied (13) [9120:9308:0326/154912.724564:ERROR:object_proxy.cc(623)] Failed to call method: org.freedesktop.DBus.ListActivatableNames: object_path= /org/freedesktop/DBus: org.freedesktop.DBus.Error.AccessDenied: An AppArmor policy prevents this sender from sending this message to this recipient; type="method_call", sender=":1.44" (uid=1000 pid=9120 comm="/snap/chromium/2406/usr/lib/chromium-browser/chrom" label="snap.chromium.chromium (enforce)") interface="org.freedesktop.DBus" member="ListActivatableNames" error name="(unset)" requested_reply="0" destination="org.freedesktop.DBus" (bus) [9120:9120:0326/154912.747078:ERROR:process_singleton_posix.cc(334)] Failed to create /home/ubuntu/.local/share/undetected_chromedriver/tmp5d0tx2fo/SingletonLock: Permission denied (13) [9325:9325:0326/154912.760216:ERROR:broker_posix.cc(43)] Invalid node channel message [9324:9324:0100/000000.761303:ERROR:broker_posix.cc(43)] Invalid node channel message [9341:9341:0100/000000.797590:ERROR:broker_posix.cc(43)] Invalid node channel message [9354:9354:0326/154912.812891:ERROR:broker_posix.cc(43)] Invalid node channel message

First of all, find location of site-packages folder, you can find it with python -m site After that in site-packages folder you need to see the undetected-chromedriver folder.

If you still get errors after this solution, you need to set your chrome version in the version_main variable in __init__.py where patcher.py is located. You can do this by using the @vsuyvkpzica46088 method or by giving your Google version to the version_main variable in the __init__.py file manually. As it says in the documentation, you need to give the value ignoring the imperfection (etc: 77.13.0 = 77). The second method works for me.

@antooro I'm running into a similar issue. Could you provide the code you are using for splitting the profile data under different folders? Are you creating a new folder as you are creating a new instance of the driver?
