Path not found when executing my python script from my cmd prompt

Question

I have a python script that uses classes from a file next to my main.py named 'src'. These classes use images from the file 'img' next to main.py as well.

I'm writting the path as follows :

"img/myImage.gif"

When I run it from my python shell it works fine but I just can't run it using the command prompt (path not found).

I tried

"/img/myImage.gif" and "./img/myImage.gif"

and also moving my 'img' file to src, and to main.py's parent file but it doesn't work..

I'm out of ideas.. any assistance would be appreciated, Thanks,

is your current working directory inside your python paths? also you'd better share your code for more clarification. — sheshkovsky

This is what you need to do for you folder structure,

program main.py src __init__.py //empty py file classA __init__.py classA.py classB __init__.py classB.py "../../img/myimage.gif" // to use in classA.py file

More Explanation:

if your main.py is in

 src main.py img myimage.gif

use this

"../img/myimage.gif"

if your folder structure is (moving img inside src)

-src main.py -img myimage.gif

you need to use like below

"img/myimage.gif"

thanks for this clarification, I think that I also have to add the path of my project to the PYTHONPATH ?

wel, i think so we should. main.py and classA.py are not in same level, and Python cant able to figure out if main.py importing classA.py module!! let me know if i m wrong. do accept this ans if this resolved your problem :)

try doing this in main.py, import os, sys PROJECT_PATH = os.path.abspath(os.path.dirname(file)) sys.path.append(PROJECT_PATH) sys.path.append(os.path.join(PROJECT_PATH, 'classA'))

my classes are found because they are imported in my main as follows: from src.classA.ClassA import ClassA but within these classes I can't load my images (from 'img')

I tried to add all this in main.py (changing 'file' with the path of my project and changing 'classA' to 'img') but it doesn't solve the problem
