Selenium on Google Colab, PermissionError: [Errno 13] Permission denied: '/content/chromedriver.exe' : I have been using Google Colab for my python projects. I want to learn & implement Selenium using Google Colab. I am trying to log in to Facebook as shown below. But, I am stuck with 'Permission error'. I have looked into various posts & tried to execute suggested solutions such as (https://stackoverflow.com/questions/49787327/selenium-on-mac-message-chromedriver-executable-may-have-wrong-permissions) but **did not help**. 

###What I've tried.
 

 1. Referred https://sites.google.com/a/chromium.org/chromedriver/home article as suggested
 2. Used chmod 755 to allow executable permissions
 3. Referenced 'chromedriver.exe' in different folders within Colab environment and but no luck

###The Code:

    import os
    from selenium import webdriver
    from selenium.webdriver.common.keys import Keys
    
    user_name = 'Username'
    password = 'Password'
    
    os.chmod('/content/chromedriver.exe', 755)
    driver = webdriver.Chrome(executable_path='/content/')
    driver.get("https://www.facebook.com")
    
    element = driver.find_element_by_id("email")
    element.send_keys(user_name)
    
    element = driver.find_element_by_id("pass")
    element.send_keys(password)
    
    element.send_keys(Keys.RETURN)
    
    driver.close()

###Complete error:

**Can someone please help me fix this issue?**

**PS:** On the long run, I want to remove my dependence on Jupyter Notebooks & rely on Cloud based Notebook environment such as Google Colab which in theory should allow me to focus on code rather than troubleshooting libraries/compatibility/permission/etc issues.
