直接上代码：

import face_recognition
import time
from PIL import Image, ImageDraw
def faceRecognition(fileName):  
    # 加载图片
    image = face_recognition.load_image_file(fileName)

    # 人脸定位
    beginTime = time.time()
    face_locations = face_recognition.face_locations(image)
    image2 = Image.open(fileName)
    pil_image = ImageDraw.Draw(image2)
    for face_location in face_locations:
     
        # 打印位置
        top, right, bottom, left = face_location
        print("A face is located at pixel location Top: {}, Left: {}, Bottom: {}, Right: {}".format(top, left, bottom, right))
     
        # 红色的边框颜色
        red_color =(255, 0, 0)
        # 边框的宽度
        border_width = 3
        # 要画红框的坐标 (x, y, x+width, y+height)
        box_coordinates = (left, top, right, bottom)
        # 画红框
        pil_image.rectangle(box_coordinates, width=border_width, outline=red_color)
        # 人脸图
        # face_image = image[top:bottom, left:right]
        # pil_image = Image.fromarray(face_image)
        # pil_image.show()
    image2.show()

if __name__ == '__main__':
    faceRecognition('10010.jpg')

运行效果为：
