Python script not running from apache when call it from PHP

Question

I have a python script which is used to remove noise from background of image. When I am calling this script from terminal it is working fine without any error. I am calling that script as below from terminal:

/usr/bin/python noise.py 1.png 100

But When I tried to calling it from PHP using apache it is giving me below error:

Traceback (most recent call last): File "./noise.py", line 2, in from PIL import Image, ImageFilter ImportError: No module named PIL

Can someone help me in resolving this issue? I tried to give permission to www-data user to that script, like this:

sudo chown www-data:www-data noise.py

But it doesn't help. Please help me.

Answer 1

Do

chmod +x noise.py

And call the Python script using full path like

system('/usr/bin/python SCRIPTFULLPATH/noise.py 1.png 100 2>&1' ,$op);

Answer 2

Try doing this

sudo chown www-data:www-data noise.py

sudo chmod ugo+xrw noise.py

sudo pip install --upgrade pip

sudo service apache2 restart

Then after try refreshing again
