I was able to get this done but please make sure to follow the steps properly. This is for the anyone who is getting import errors.

Step1: Check if files and folders have got execute permission issue. Linux user use:

chmod 777 filename

Step2: Check which user has the permission to execute it.

Step3: open terminal type this command.

sudo visudo

add this lines to the code below

www-data ALL=(ALL) NOPASSWD:ALL
nobody ALL=(ALL) NOPASSWD:/ALL

this is to grant permission to execute the script and allow it to use all the libraries. The user generally is 'nobody' or 'www-data'.

now edit your code as

echo shell_exec('sudo -u the_user_of_the_file python your_file_name.py 2>&1');

go to terminal to check if the process is running type this there...

ps aux | grep python

this will output all the process running in python.

Add Ons: use the below code to check the users in your system

cut -d: -f1 /etc/passwd

Thank You!
