Face Detection API Error

Question

I am trying to use the Azure face detection API only to detect faces in an image but I am getting the following API error:

Traceback (most recent call last):  File "main.py", line 14, in <module>    detected_faces = face_client.face.detect_with_url(image_path)  File "/Library/Frameworks/Python.framework/Versions/3.9/lib/python3.9/site-packages/azure/cognitiveservices/vision/face/operations/_face_operations.py", line 547, in detect_with_url    raise models.APIErrorException(self._deserialize, response)azure.cognitiveservices.vision.face.models._models_py3.APIErrorException: (InvalidRequest) Invalid request has been sent.

Below is my code:

from azure.cognitiveservices.vision.face import FaceClientfrom msrest.authentication import CognitiveServicesCredentials

SUBSCRIPTION_KEY = 'X'
ENDPOINT = 'Y'

# Create an authenticated FaceClient.
face_client = FaceClient(ENDPOINT, CognitiveServicesCredentials(SUBSCRIPTION_KEY))


# Detect faces in an image 
fileimage_path = 'test.jpg'
with open(image_path, 'rb') as image_file:    
	detected_faces = face_client.face.detect_with_url(image_path)


# Print the face IDs and locations
for face in detected_faces:    
	print(f"Face ID: {face.face_id}")    
  	print(f"Face location: x={face.face_rectangle.left}, y={face.face_rectangle.top}, w=		  {face.face_rectangle.width}, h={face.face_rectangle.height}")

Answer 1

The answers given above are wrong, the problem is that the default value of

return_face_id

in both detect_with_url and detect_with_stream is True, but returning face ID's is now a restricted feature.

So for all calls of detect_with_url and detect_with_stream , you have to manually / explicitly set return_face_id to False , e.g.

detect_with_stream(..., return_face_id=False)
