Update:
I have used the face_client.face.detect_with_url before and it worked.So my network should be fine (maybe, I guess). However, when I switched to the face_client.face.detect_with_stream, it still got the errors... Finally, I rewrote my code with referring to Azure Detect faces API, how to change the URL picture to a local picture?, and it could operate successfully. I'm still not sure why the previous question happened, but your advices @ Jim Xu, @ Satya V are appreciated!
After passing the official example (Microsoft Cognitive Services) to do the face detection via python. I have tried to detect the face with a local image. However, i am getting some errors....
The official codeļ¼
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)
Refer to the official code, My code is:
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)
However, there are some error
