Undetected Chrome Driver Idle for 2 mins and start runing again everytime

[harika09]

Hi, I just want to ask about the problem I encounter every time I run the driver and for multiple instances. I have 100 tasks and every time the driver runs it will load the page, login user information, and then quit using the driver. quit ()

It will run smoothly five to eight times, but after that it will idle for 2 to 3 minutes before running again. It will repeat the process, and every time it hits 5, or 8, it will idle again and again. My question is how to stop the idle time? I just want to run the task without the idle of 2 to 3 minutes.

Here is my sample code

import pickle
from multiprocessing import freeze_support
import undetected_chromedriver.v2 as uc
import time
import csv
from selenium.webdriver.common.by import By
from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.support import expected_conditions as EC

from colorama import Fore, Back, Style
colorama.init(autoreset=True)
freeze_support()

time_out = 5000

def undetectedChrome():

        def titanLOgin(Email, Password):
            # options = webdriver.ChromeOptions()
            driver = uc.Chrome(
                            executable_path=r"../HRB 1.0/system/chromedriver.exe")
            try:
                def titan():

                    now = datetime.datetime.now()
                    try:
                        driver.get('https://titan22.com/account/login?return_url=%2Faccount')

• When your login fail your code is recursive, that's really not a good idea.
• You should use a shorter timeout : yours is 5000 second which is more than an hour, so if the page load fails for whatever reason you're stuck with an idle driver that takes a lot of memory. Please use selenium.common.exceptions.TimeoutException instead.
• You don't show how you launch your threads or processes so it's very hard to guess what you're doing wrong.

I'm just running a single thread. I will send the whole folder here. Please check. It will help me a lot.  Thank you You can see that it will run smoothly for the 1st to 4th task but after that it will stop for 2-5 mins and run the task again

I got the same problem

[PePinodemrs]

I think that the problem comes at the moment when it is necessary to leave the driver and it takes time, but also to launch it. The problem is present only when there are a lot of tasks and I think it's when it's going to download the info from google apis chrome, not the time of download but rather a blocking at google api level

[harika09]

it happens after every 6 or 5 tasks. I don't know if the driver or when saving the google login session

[Lanshuns]

same here, im doing a while loop and it stops every 6/5 tasks

[Lanshuns]

@harika09, @henzycuong1 please if any of you guys fixed this issue let me know

[harika09]

@harika09, @henzycuong1 please if any of you guys fixed this issue let me know

Nope still having this issue.

[sebdelsol]

Nobody provide minimum code to reproduce this so called issue, and those comments are moot. At the moment the only actual occurrence of this "bug" is this weird recursive mess you'll find above : it's surprising it even works.

Those kind of "bugs" could be bad configurations, huge Selenium timeouts, drivers not properly disposed, race conditions in multi-thread env, slow proxies, rate limitation or bot behaviors detection from site throwing your script into black holes to prevent naive scrapping attempts... you name it, there are so many things that can go wrong with a complex package like Selenium.

Please try to stick to best practices for bugs reporting, and maybe we'll find out there's something to be fixed that'll benefit the community.

[PePinodemrs]

it's just a simple code like uc.Chrome() but when i start 2-3 chrome in the same time it's okay but more they are stuck sometimes

[sebdelsol]

sure, but how do you "start" several Chromes at the same time ? Please show some code to reproduce the issue, I can't reproduce this on my side hence the suspicion you're doing something weird.

what about @harika09's code? i've downloaded his code and set the timeout to 5 instead and still the same issue, he uses no proxies or anything just simple code as you can see

[PePinodemrs]

bien sûr, mais comment "démarrer" plusieurs Chromes en même temps ? Veuillez montrer du code pour reproduire le problème, je ne peux pas le reproduire de mon côté, d'où le soupçon que vous faites quelque chose de bizarre.

With a simple threading or multiprocessing

[PePinodemrs]

But the famous bug is present for versions 97 to 103 and not from 92 to 96

Bref, sans code je ne peux pas faire grand chose, j'entends bien qu'il y a un potentiel problème, mais comment le résoudre avec aussi peu d'indices ?

[harika09]

@sebdelsol Here is my sample code. I'm just loading the Google login page here. I have 13 tasks on my GOOGLEACCOUNT.csv and after 6 tasks, it will stop and re-run again after a few minutes.

from multiprocessing import Process, freeze_support
import undetected_chromedriver as uc
from selenium.webdriver.chrome.service import Service
import time
import csv
freeze_support()

def googleLogin(email, password):
    options = uc.ChromeOptions()
    driver = uc.Chrome(use_subprocess=True,service=Service("/chromedriver.exe"),options=options)
    driver.get('https://accounts.google.com/ServiceLogin/identifier?service=mail&passive=1209600&osid=1&continue=https%3A%2F%2Fmail.google.com%2Fmail%2Fu%2F0%2F&followup=https%3A%2F%2Fmail.google.com%2Fmail%2Fu%2F0%2F&emr=1&flowName=GlifWebSignIn&flowEntry=ServiceLogin')
    print('Loaded')
    time.sleep(1)
    driver.quit()

file = open("GOOGLEACCOUNT.csv")
reader = csv.reader(file, delimiter=',')
next(reader)

for data in reader:
    googleLogin(data[0], data[1])

if __name__ == "__main__":
    googleLogin() 

[PePinodemrs]

from threading import Thread from selenium.webdriver.support.ui import WebDriverWait from selenium.webdriver.common.by import By def name(): while True: options = ChromeOptions() options.add_argument('--load-extension=C:/adblock') driver = uc.Chrome(version_main=101, browser_executable_path = my_path, options = options) driver.get('https://www.ecoledirecte.com/login') wait = WebDriverWait(driver, 5) el = wait.until(expected_conditions.element_to_be_clickable((By.XPATH, '//*[@id="username"]'))) el.click()

   ..........other things but not interesting

   driver.close()
   driver.quit()

if name == 'main': for i in range(10): Thread(target=name, args=()).start()

My problem is that when I launch the 10 drivers in an infinite loop after three rounds of the loop so only three I start to have problems on half of the drivers but each time they are not all concerned in each round but only about half. And what happens is that the driver launches, it loads the page and it stops in front of the login where it must click and it waits for a long time (0 to a few minutes) before skipping it without making any error and moving on to the rest of the code and yet it works very well on the versions 92 to 96 but from 97 to 103 the problem is present

[Lanshuns]

@sebdelsol or please tell us what chrome version you use or your undetected-chromedriver configuration

[sebdelsol]

Always the last one, why bother ?

[harika09]

Always the last one, why bother ?

Did you already check this sir? https://github.com/ultrafunkamsterdam/undetected-chromedriver/issues/632#issuecomment-1152825337

[PePinodemrs]

Always the last one, why bother ?

Did you already check this sir? #632 (comment)

i have a little problem like that it the time that undetected-chromedriver download the driver from the source i think and also while leaving the driver when there is a lot of task

[PePinodemrs]

Always the last one, why bother ? it's to have a lot of version to change user agent and not being detected because if i change manualy it's easier detected

[sebdelsol]

I've tried @PePinodemrs code...

• It works like a charm, I use the lastest Chrome version which is 102 at this moment. I can't reproduce your "delays".
• Please provide working code... I had to fix it.
• Please learn how to format code on Github, check here.

Some notes:

• Don't use user agents.
• Having several chrome versions requesting stuff on a site from the same IP is quite suspicious.
• You don't need to close AND quit the driver, quit() is enough.
• You should have a try, except, clause to handle timeouts (or other possible errors) and finally properly quit the driver... that's a possible explanation for those "delays".
• You have nothing to properly break your infinite loops and join your threads when you stop your script, you'll certainly end up clogging your system... then... having "delays".
• I don't understand why you need to quit and recreate a driver each iteration, a driver can easily be reused...

i have to quit and reload driver because i have to clear the cache

[sebdelsol]

Are you sure deleting cookies is not enough ? driver.delete_all_cookies()

[PePinodemrs]

i will retry but i think it's not

[harika09]

Are you sure deleting cookies is not enough ? driver.delete_all_cookies()

tried this but still same problem

[henzycuong1]

everyone here used multithread the uc on the hdd disk, didn't it?

[sebdelsol]

Now I've tried @harika09 code...

• It works like a charm too, there's no "delays"
• Your code is broken too... I had to fix it.

Some notes:

• Don't use use_subprocess=True but protect your main entry point instead, please check here.
• freeze_support() is supposed to be used behind your protected main entry point. Please check here. Anyway I don't see why you need it.
• Why do you create a Selenium Service ? This won't be used since extra **kwargs are disposed when the chromedriver is initialized !
• I don't understand why you need to quit and recreate a driver each iteration, a driver can easily be reused...

undetected chrome driver won't open if I don't add use_subprocess=True when compiled using Pyinstaller

I need to close and re-open the driver to save google account session using pickle

can you share your code with us so we can compare?

I tried your code but still stop when hits task 6 and waits for 2-3 mins. got this message: selenium.common.exceptions.WebDriverException: Message: chrome not reachable (Session info: chrome=102.0.5005.115)

hey sorry for bothering again, but what did you meant by driver can easily be reused i didn't really get it can you explain this point? thanks

[sebdelsol]

@Stainpy : you don't quit() it but get() another url, since quitting and recreating a driver is quite costly.

[Lanshuns]

@harika09 hey, try use driver.close() instead of driver.quit()

[sebdelsol]

@Stainpy : that's really not a good idea, if you only close your driver you'll end up with its process still running, you should quit it if you want everything to be cleaned up.

[Lanshuns]

@Stainpy : that's really not a good idea, if you only close your driver you'll end up with its process still running, you should quit it if you want everything to be cleaned up.

indeed, i use quit now only if unexpected error happened or after some tasks to clean up, i will use this as a temporary solution until i find out how to reuse the driver
