Fatal Python error: Cannot recover from stack overflow error using Selenium and ChromeDriverManager

Question

My code worked fine until a few days ago. But now I'm facing an error as follows:

Fatal Python error: Cannot recover from stack overflow

with the minimal code:

Error:

What's the cause of the sudden errors?

Answer 1

This error message...

...indicates that ChromeDriverManager is initiating multiple threads while trying to download the ChromeDriver and is reaching the limit of the interpreter stack during that infinite recursive loop.

This usecase

I don't see any significant error in your code block as I was able to execute similar lines of code on my windows-10 box perfecto:

• Code block:

  from selenium import webdriver
  from selenium.webdriver.chrome.options import Options
  from selenium.webdriver.chrome.service import Service as ChromeService
  from webdriver_manager.chrome import ChromeDriverManager
  
  options = Options()
  options.add_argument("start-maximized")
  driver = webdriver.Chrome(service=ChromeService(ChromeDriverManager().install()), options=options)
  driver.get('https://pypi.org/')
  

• Console output:

  ====== WebDriver manager ======
  Current google-chrome version is 110.0.5481
  Get LATEST chromedriver version for 110.0.5481 google-chrome
  Trying to download new driver from https://chromedriver.storage.googleapis.com/110.0.5481.77/chromedriver_win32.zip
  Driver has been saved in cache [C:\Users\debanjan.bhattacharj\.wdm\drivers\chromedriver\win32\110.0.5481.77]

Solution

As a preventive measure you can:

• Upgrading requests
• Reinstall WebDriver manager
• Reinstall Selenium-Python
