php script error while executing python script and importing webdriver from selenium

Question

I am executing python script from php which is importing webdriver from selenium but I am getting error

Traceback (most recent call last): File "/var/www/html/spreadsheet/script.py", line 10, in from selenium import webdriver ImportError: No module named selenium

Selenium is installed and python script is working perfectly from bash. i have also run it from sudo but still getting the same error.

my php script is

$dir = __DIR__;
$command = "sudo -u www-data python ".$dir."/script.py 2>&1";

$pid = popen( $command,"r");

while( !feof( $pid ) )
{
 echo fread($pid, 256);
 flush();
 ob_flush();
 usleep(200000);
}
pclose($pid);

and in script.py i am getting eror

from selenium import webdriver
import time
import os
import os.path

so i am getting error while importing webdriver.

Answer 1
