Can't launch in Google Colab

[megalevel]

Hello!

I am trying to execute the code in the Google Colab environment, but I get an error. My code:

!pip install -U seleniumbase

from seleniumbase import Driver

driver = Driver(uc=True, headless=True)

try:
    driver.open("https:/www.investmint.ru/")
    driver.sleep(10)
finally:
    driver.quit()

print('driver:\n',driver.page_source)

Error:

That's a popular issue from undetected-chromedriver, with 40 open tickets so far: https://github.com/search?q=repo%3Aultrafunkamsterdam%2Fundetected-chromedriver+%22from+chrome+not+reachable%22&type=issues

To get around that, use the SB Manager format, (similar to the Driver Manager format), which has extra internal code for handling that (by using a virtual display in a headless environment). Here's a sample script: (https://github.com/seleniumbase/SeleniumBase/blob/master/examples/raw_uc_mode.py)

from seleniumbase import SB

with SB(uc=True, test=True) as sb:
    url = "https://gitlab.com/users/sign_in"
    sb.driver.uc_open_with_reconnect(url, 3)
    if not sb.is_text_visible("Username", '[for="user_login"]'):
        sb.driver.uc_open_with_reconnect(url, 4)
    sb.assert_text("Username", '[for="user_login"]', timeout=3)
    sb.assert_element('label[for="user_login"]')
    sb.highlight('button:contains("Sign in")')
    sb.highlight('h1:contains("GitLab.com")')
    sb.post_message("SeleniumBase wasn't detected", duration=4)

You could also use SeleniumBase's BaseCase format with pytest --uc.

Here's an example script using that format: (https://github.com/seleniumbase/SeleniumBase/blob/master/examples/verify_undetected.py)

from seleniumbase import BaseCase
BaseCase.main(__name__, __file__, "--uc", "-s")

class UndetectedTest(BaseCase):
    def test_browser_is_undetected(self):
        url = "https://gitlab.com/users/sign_in"
        if not self.undetectable:
            self.get_new_driver(undetectable=True)
        self.driver.uc_open_with_reconnect(url, 3)
        if not self.is_text_visible("Username", '[for="user_login"]'):
            self.get_new_driver(undetectable=True)
            self.driver.uc_open_with_reconnect(url, 4)
        self.assert_text("Username", '[for="user_login"]', timeout=3)
        self.post_message("SeleniumBase wasn't detected", duration=4)
        self._print("\n Success! Website did not detect Selenium! ")

Use self.driver to access the raw driver.
See https://github.com/seleniumbase/SeleniumBase/tree/master/examples for lots of examples.
See https://github.com/seleniumbase/SeleniumBase/blob/master/help_docs/method_summary.md for a list of methods.

Thank you for your reply, I really appreciate it.
I tried to follow your recommendations, but I get the error again.
I will be grateful for any help!

Where is Chrome installed on that machine? It might not be in the default location (if it's installed at all). Use binary_location to set the location of Chrome (not to be confused with chromedriver, which is different).

If you're using the SB() format, then you don't need to include sbvirtualdisplay, as that is already used with SB() on Linux machines.

Also try with SB(uc=True, headless=False, xvfb=True) as sb: because you don't need headless mode if you're using xvfb=True for the virtual display. Try different combination of that if it doesn't work for you, but first make sure Chrome is installed. If Chrome was already installed, set the location with binary_location.

@megalevel Sorry, did you manage to run seleniumbase on colab?

[mdmintz]

Someone from the SeleniumBase Discord server got it working on Google Colab with:

from seleniumbase import SB
import subprocess
import nest_asyncio
nest_asyncio.apply()

# Start an Xvfb session
subprocess.run(['xvfb-run', '-a'])

from seleniumbase import SB

with SB(uc=True, test=True, headed=True, locale_code="en") as sb:
    sb.activate_cdp_mode(URL)
    # ...
