Description

Describe what you were trying to get done.
Tell us what happened, what went wrong, and what you expected to happen.
IMPORTANT: If your issue is related to a specific picture, include it so others can reproduce the issue.

What I Did

import os
import cv2
import face_recognition

Function to load images from a folder and encode them

def load_and_encode_images(folderPath):
PathList = os.listdir(folderPath)
print("Found images:", PathList)

imgList = []
studentIds = []

for path in PathList:
    img_path = os.path.join(folderPath, path)
    img = cv2.imread(img_path)

    if img is None:
        print(f"Error loading image: {img_path}")
        continue

    # Convert image to RGB format
    img_rgb = cv2.cvtColor(img, cv2.COLOR_BGR2RGB)
    imgList.append(img_rgb)
    studentIds.append(os.path.splitext(path)[0])

encodeList = []
for img in imgList:
    try:
        # Ensure image is 8-bit RGB or grayscale
        if img.shape[2] != 3:
            print(f"Skipping image {img}: not 8-bit RGB")
            continue

        encode = face_recognition.face_encodings(img)[0]
        encodeList.append(encode)
    except IndexError:
        print(f"No face found in image: {img}")
        # You can choose to skip this image or handle the error as needed

return encodeList, studentIds

Example usage

folderPath = 'Images'
print("Encoding started .......")
encodeListKnown, studentIds = load_and_encode_images(folderPath)
print("Encoding complete")

Print the results

print("Encoded faces:", encodeListKnown)
print("Student IDs:", studentIds)

Paste the command(s) you ran and the output.
If there was a crash, please include the traceback here.

change this:
rgb_small_frame = small_frame[:, :, ::-1]
to
rgb_small_frame = cv2.cvtColor(small_frame, cv2.COLOR_BGR2RGB)
