[itsvijaychoudhary]

What did you do?

I have just append the images in face recognition project

What did you expect to happen?

I want to print the total number of images

What actually happened?

I got an ImportError

What are your OS, Python and Pillow versions?

• OS: MacOS M1 Sonoma 14.3
• Python: 3.11.4
• Pillow: 9.0.0

import cv2

You're importing Pillow in your code, but you're not using it. So if your goal is to just run the code you've posted, and you believe Pillow is in your way, then you can stop importing Pillow.

import cv2
import face_recognition
import pickle
import os

# importing the student images

folderPath = 'Images'
modePathList = os.listdir(folderPath)
imgList = []
for path in modePathList:
    imgList.append(cv2.imread(os.path.join(folderPath, path)))
print(len(imgList))

However, Iooking at your error, I don't think Pillow is the cause of your problem. I think face_recognition is. I would suggest

import cv2
import os

# importing the student images

folderPath = 'Images'
modePathList = os.listdir(folderPath)
imgList = []
for path in modePathList:
    imgList.append(cv2.imread(os.path.join(folderPath, path)))
print(len(imgList))

If that does solve your problem, but you would still like to use face_recognition, that isn't a Pillow problem, so I would suggest that this is a matter for https://github.com/ageitgey/face_recognition or https://stackoverflow.com/.

To be helpful though, Homebrew/homebrew-core#153177 suggests that running brew reinstall librist might fix your issue.

thank you it worked for me. I just need to import cv2 and os

[itsvijaychoudhary]

but I'm still getting the same error when i'm using face_recognition library and now i'm using it in the code.
how do i solve that?

i run brew reinstall librist and after that i run the same program in pycharm and got this error.

Again, the problem you're describing is not a Pillow one, so there are other places that would be more helpful to you.

ageitgey/face_recognition#1534 and ageitgey/face_recognition#1536 are face_recognition users asking very similar questions. You might want to ask if they ever found a solution.
