Opening Firefox in python using selenium

Question

My System: Ubuntu 14.04

Firefox version: 45.0

selenium package: 3.4.2

I have geckodriver in PATH. Selenium is installed. But when I run:

from selenium import webdriver
d = webdriver.Firefox()

I get an error:

d = webdriver.Firefox()

OSError: [Errno 20] Not a directory

Can anyone tell me what is wrong.

Initially I had problem with missing geckodriver but once I added that to path, I am getting above error.

Make sure the geckodriver path is the folder path that contains geckodriver (not the actual executable file path).
