Run selenium using crontab (python)

I have a python script that calls chrome through selenium with the following line.

 ff = webdriver.Chrome('/home/user01/webScraping/CollectAndGo/chromedriver')

The python script is invoked from a shell script.

python /home/user01/webScraping/CollectAndGo/cgcom.py > /home/user01/webScraping/CollectAndGo/cgcom.log 2>&1

When I run the script from the terminal or just execute the .sh file, it works fine, but when I plan to run crontab, it fails with the following error.

   raise exception_class(message, screen, stacktrace)
selenium.common.exceptions.WebDriverException: Message: u'unknown error: Chrome failed to start: exited abnormally\n  (Driver info: chromedriver=2.9.248304,platform=Linux 3.5.0-36-generic x86_64)'

The error is related to the first line of code for this question. Does anyone know why this might happen?
