PIL not recognised in subprocess

[bobtbown]

I have a script to show images using the the import "from PIL import Image, ImageTk" and it works fine when running the script by itself. I have Pillow installed.

However, when I call the script as a subprocess from another script it says "ModuleNotFound error No Moule named PIL"

What do I need to change to get the PIL recognised in the subprocess.

thanks any help would be much appreciated.

How do you launch the subprocess? Can you post the lines that launch the subprocess. Aren't you using a different Python interpreter?

As mention more info is needed,also what OS do you use.
Basic test that you can do from command line.

G:\div_code\po_env
λ python -c "import sys; print(sys.executable)"
C:\python312\python.exe

G:\div_code\po_env
λ python -c "import PIL; print(PIL.__file__)"
C:\python312\Lib\site-packages\PIL\__init__.py

G:\div_code\po_env
λ pip -V
pip 23.2.1 from C:\Python312\Lib\site-packages\pip (python 3.12)

G:\div_code\po_env
λ python open_tk.py

See that same Python interpreter is used,then i call it like this working.
tk_image_open.py is similar code as code as you have,a Tkinter app that use Pillow to show a image.

# open_tk.py
import subprocess
import sys

# Assuming tk_image_open.py is in the same directory
script_path = "G:/div_code/po_env/tk_image_open.py"

# Use sys.executable to ensure the same Python interpreter is used
subprocess.run([sys.executable, script_path])
