为什么face_recognition.face_locations抛出“不支持的图像类型，必须是8位灰度或RGB图像。”

Question

OpenCV-python 4.10.0.84

Python 3.12

我正在处理此图像：https://drive.google.com/file/d/1YqLiwUmFC0Nh7O1_ee6Z4hpefEygnEIN/view?usp=sharing。这是jpg

import cv2
import face_recognition

def face_fun(image_file_path):
    # Load the image
    image = cv2.imread(image_file_path)
    rgb_image = cv2.cvtColor(image, cv2.COLOR_BGR2RGB)

    # Find all the faces and face encodings in the image
    face_locations = face_recognition.face_locations(rgb_image) # Exception thrown

Answer 1

解决方案是将 numpy 降级到 1.26.0。这解决了我的问题。 请参阅 [[已解决]] 人脸识别测试失败且图像正确
