如何使用Python在Face API调用（Microsoft认知服务）中使用本地照片进行处理

更新：

我以前使用过

face\u client.face.detect\u with\u url

，效果很好。所以我的网络应该很好（我想可能吧）。但是，当我切换到

face\u client.face.detect\u with\u stream

时，它仍然收到错误。。。最后，我用reference重写了代码，它可以成功运行。我仍然不知道为什么会出现上一个问题，但非常感谢您的建议@Jim Xu，@Satya V

---

通过官方示例（Microsoft认知服务）后，通过python进行人脸检测。我尝试用局部图像检测人脸。然而，我得到了一些错误

官方代码：

group_photo = 'test-image-person-group.jpg'
IMAGES_FOLDER = os.path.join(os.path.dirname(os.path.realpath(__file__)))
# Get test image
test_image_array = glob.glob(os.path.join(IMAGES_FOLDER, group_photo))
image = open(test_image_array[0], 'r+b')

# Detect faces
face_ids = []
faces = face_client.face.detect_with_stream(image)

参考官方代码，我的代码是：

IMAGES_FOLDER='' #the image path
test_image_array = glob.glob(os.path.join(IMAGES_FOLDER, '*jpg'))
image = open(test_image_array[0], 'r+b')
faces = face_client.face.detect_with_stream(image)

然而，也有一些错误
