Python-pillow: problem with Image.open()
Paste your formatted code into a gist.github.com or bpaste its easier to read. When you start a process to run a python command, the cwd should be the current directory you are located in. So it depends on how you start the python process. Here is an example of the current working directory changing as i change my directory on my machine. https://bpa.st/SOOA Note that the current working directory changes as i change where i start the processes from. You might not be located within the directory that contains the file when you start the process. You can debug this with a print(os.getcwd()) line in the code. Using an absolute path might be a better solution. To get around this in production code we specify a environment variable called project_home which points to the location of the source code on the machine, then refer to files relative to this point, this enables the code to be moved to different machines and not break. more at. https://sites.pitt.edu/~naraehan/python3/file_path_cwd.html More on reddit.com

PIL Image Close Method Not Working?
PIL’s show doesn’t know anything about the displaying process once it’s been started (it’s intended for debugging, so a human should be there anyway). There are ways to try to find the open application and kill it but they’re outside the scope of what you can do with PIL. See this stackoverflow post for more info. More on reddit.com

Does open() uses PIL or Pillow when opening image files?
No it does not. But you could have overwritten the regular open with some odd import or some other code line. There is no way a regular open throws a PIL exception, perhaps you had a different error? More on reddit.com

r/learnprogramming on Reddit: Python-pillow: problem with Image.open()
January 9, 2022 -

I really searched the web and tried different paths and images but I don't see the mistake I made.

I want to build a simple GUI with tkinter and I want to show an Image in a Label. Therefore first of all I want to read in the image which is in the same folder as my python file. Maybe someone can have a look and give me a hint.

from tkinter import *
import os
from PIL import ImageTk, Image
root = Tk()
root.title("Image Collector")
#Default Settings(Variables)
status_start_stop = False
img_save_to_path = "test/"
test_img = ImageTk.PhotoImage(Image.open("test.png")) #this one is the line which causes the error

.... (there is more unproblematic code)

output:

FileNotFoundError: [Errno 2] No such file or directory: 'test.png'

The file exists in the same folder as the programm and the name is definitly correct. I copied and pasted it like a 1000 times and also tried different images. I tried creating a subfolder called images and tried to call Image.open("images/test.png") but that didn't work either.

PS: I run an Ubuntu based distribution if that is needed
