PIL version: 9.4.0
OS: Windows 10.

I have installed PIL in custom directory named contrib, using

pip install PIL-t ./contrib

And from test.py which is outside contrib directory, I have imported as shown below by adding contrib to sys path.

import sys
import os
sys.path.append(os.path.join(os.path.dirname(__file__), "contrib" ))
from PIL import Image
# from contrib.PIL import Image
im = Image.open(r"image.jpg") 
  
# This method will show image in any image viewer 
im.show()

and it throws the error.

Traceback (most recent call last):
  File ".\test.py", line 15, in <module>
    from PIL import Image
  File ".\contrib\PIL\Image.py", line 103, in <module>
    from . import _imaging as core
ImportError: DLL load failed while importing _imaging: The parameter is incorrect.

Even below import throws error.

from contrib.PIL import Image
import contrib.PIL.Image

However, it is working when it is installed in default location lib. Am i missing something like adding dll part in windows or something like that??
