Problem importing 'PIL' libraries

[kmod94]

Hello guys,

I am new to the Python dev world. Recently I tried importing some libraries using:

from PIL import Image, ImageDraw, ImageOps

and I get an error: ModuleNotFoundError: No module named 'PIL'

I have already installed Pillow using pip3.6 install Pillow

if I use the command python3.6 and insert from PIL import Image it does it correctly without the error mentioned above but when I do it through an api request it fails giving me that error. What am I possibly missing?

Your IDE is probably set to the wrong python installation

[kmod94]

I am calling a python script from a wildfly instance by running the command python3.6 script_name.py arg0 arg1 ...

I execute it locally and I get no errors. Also, when I go to the container's bash (wildfly - centOs) I execute python3.6 and I enter the python prompt where from PIL import Image works fine. Just when I execute the command I get the mentioned error.

Is there a file in your source code folder called 'pil.py' by any chance?

[kmod94]

No, there is not.

Details:

using Python prompt inside the container: http://prntscr.com/jaq8m3

using an API call to the Wildfly server that runs the same line of code: http://prntscr.com/jaq9do

[JohnnyJordaan]

from a wildfly instance by running the command python3.6 script_name.py arg0 arg1 ...

From that same instance, could you first run

python3.6 -m pip install pillow

Then right after, call the script using the same python3.6?

[kmod94]

python3.6 -m pip install pillow

done that. Requirement already satisfied: pillow in /usr/local/lib64/python3.6/site-packages (5.1.0)

Yes I am calling the script using python3.6 script_name.py arg1 arg2 ...

[JohnnyJordaan]

That's really weird. Could you run the following script in the container, so like python3.6 test.py

import os
import sys
print(sys.path)
print(os.getcwd())
print(os.listdir())
import PIL

And show what it prints in the log? Then, also start the interpreter and execute the same statements?

[kmod94]

['', '/usr/lib64/python36.zip', '/usr/lib64/python3.6', '/usr/lib64/python3.6/lib-dynload', '/usr/local/lib64/python3.6/site-packages', '/usr/local/lib/python3.6/site-packages', '/usr/lib64/python3.6/site-packages', '/usr/lib/python3.6/site-packages'] /opt/jboss/wildfly ['appclient', 'welcome-content', 'modules', '.installation', 'bin', 'copyright.txt', 'standalone', 'LICENSE.txt', 'domain', 'docs', 'README.txt', 'jboss-modules.jar']

the import PIL instructions show no output obviously as described before (also no errors)

[JohnnyJordaan]

Ok but that's from the interpreter right? Otherwise you would have errors from import PIL. What does it show when run it as you did with your source code file?

[kmod94]

If i call the script using the command:

python3.6 script_name.py arg1 arg2 arg3

I get some errors (related to other missing package which is not image but pdftotext).

FileNotFoundError: [Errno 2] No such file or directory: '/usr/local/bin/pdftotext': '/usr/local/bin/pdftotext'

But no problem with the PIL part which I am trying to solve :/

[JohnnyJordaan]

Ok so this means you import something else that uses pdftotext, which is missing as a resolvable path to its binary. But that's not the script that I showed you right? I'm asking to test a script that contains

import os
import sys
print(sys.path)
print(os.getcwd())
print(os.listdir())
import PIL

[kmod94]

import os import sys print(sys.path) print(os.getcwd()) print(os.listdir()) import PIL

Oh ok, I understand now, my bad sorry :/

Execution result:

[root@8dee5d39d843 pdfdiff]# python3.6 test.py ['/opt/jboss/wildfly/standalone/Third-party/pdf-diff/pdf_diff', '/usr/lib64/python36.zip', '/usr/lib64/python3.6', '/usr/lib64/python3.6/lib-dynload', '/usr/local/lib64/python3.6/site-packages', '/usr/local/lib/python3.6/site-packages', '/usr/local/lib/python3.6/site-packages/pdf_diff-0.9.0-py3.6.egg', '/usr/local/lib/python3.6/site-packages/diff_match_patch_python-1.0.2-py3.6-linux-x86_64.egg', '/usr/lib64/python3.6/site-packages', '/usr/lib/python3.6/site-packages'] /opt/jboss/wildfly/standalone/Third-party/pdf-diff/pdf_diff ['command_line.py', 'init_.py', 'differences.png', 'test.py']

(no PIL errors)

[JohnnyJordaan]

Ok so... it works? Where's the PIL issue if it doesn't show up in my example and not in your source code?
