How to get Splunk to run my Python shell script?

I am trying to use the Splunk Synthetic App in order to set up and monitor fake transactions that I create with Python. I am running into problems when I try and get Splunk to run my shell script (Test2^SplunkOpenTest^.sh) which calls my Python program (Test2^SplunkOpenTest^.py) on a Linux VM. I go to Settings -> Data Inputs > Scripts and set the sourcetype and index to both be synthetic but somehow Splunk doesn’t collect the data even though the program works when I run it from the Linux terminal. Because of this I looked inside the Splunkd.log file and noticed that every 60 seconds when Splunk is supposed to get the data from the script, it gives an error that looks like this:

06-20-2016 12:07:19.638 -0400 ERROR ExecProcessor – message from “/opt/splunk/etc/apps/splunk-app-synthetic/bin/Test2^SplunkOpenTest^.sh ImportError: No module named selenium

I have tried to figure this out for a day now and I feel like I’m missing something so simple but for the life of me I cannot figure out what that is. My Test2^SplunkOpenTest^.sh file looks like so:

#!/bin/bash
unset PYTHONPATH
unset LD_LIBRARY_PATH
CLASSPATH=”/usr/lib/pyth/selenium-server-standalone-2.53.0.jar”
export CLASSPATH
SELENIUM_SERVER_JAR=”/usr/lib/pyth/selenium-server-standalone-2.53.0.jar”
export SELENIUM_SERVER_JAR
python /opt/splunk/etc/apps/splunk-app-synthetic/bin/Test2^SplunkOpenTest^.py

And my Test2^SplunkOpenTest^.py file looks like:

from selenium import webdriver
from selenium.webdriver.common.by import By
from selenium.webdriver.common.keys import Keys
from selenium.webdriver.support.ui import Select
from selenium.common.exceptions import NoSuchElementException

from splunktransactions import Transaction
class SplunkOpenTest(unittest.TestCase):
    def setUp(self):
        self.driver = webdriver.Firefox()
        self.driver.implicitly_wait(30)
        self.base_url = "http://localhost:8000/en-US/account/login?return_to=%2Fen-US%2F"
	time.sleep(5)
        self.verificationErrors = []
        self.accept_next_alert = True
    def test_splunk_open(self):
        driver = self.driver
	a=Transaction(driver, 'Splunk')
	a.TransactionStart(driver, 'Splunk Login Page')
        driver.get(self.base_url + "/")
	a.TransactionEnd(driver, 'Splunk Login Page')
	time.sleep(4)
    def is_element_present(self, how, what):
        try: self.driver.find_element(by=how, value=what)
        except NoSuchElementException as e: return False
        return True
    def is_alert_present(self):
        try: self.driver.switch_to_alert()
        except NoAlertPresentException as e: return False
        return True
    def close_alert_and_get_its_text(self):
        try:
            alert = self.driver.switch_to_alert()
            alert_text = alert.text
            if self.accept_next_alert:
                alert.accept()
            else:
                alert.dismiss()
            return alert_text
        finally: self.accept_next_alert = True
    def tearDown(self):
        self.driver.quit()
        self.assertEqual([], self.verificationErrors)
if __name__ == "__main__":
    unittest.main()

I appreciate the assistance with this!
