DeepFace analyze function rises serialization issue-CodePudding

i would like to use deepface algorithm for detection human's emotion from the image, here is my code :

import  cv2
from deepface import DeepFace
import numpy as np
import json
image =cv2.imread('emotion.jpg')
#json.dumps(image)
analyze =DeepFace.analyze(image,actions='emotions',enforce_detection=False)
print(analyze)

but when i have run the code, got the following error

C:\Users\User\PycharmProjects\AI_Project\venv\Scripts\python.exe C:\Users\User\PycharmProjects\AI_Project\emotion_detection.py 
Action: e:   0%|          | 0/8 [00:00<?, ?it/s]
Traceback (most recent call last):
  File "C:\Users\User\PycharmProjects\AI_Project\emotion_detection.py", line 7, in <module>
    analyze =DeepFace.analyze(image,actions=('emotions'),enforce_detection=False)
  File "C:\Users\User\PycharmProjects\AI_Project\venv\lib\site-packages\deepface\DeepFace.py", line 452, in analyze
    resp_obj["region"][parameter] = int(region[i]) #int cast is for the exception - object of type 'float32' is not JSON serializable
IndexError: list index out of range

Process finished with exit code 1

i have searched a lot about this problem, for instance try the following code

json.dumps(image)

but when i run, got :

TypeError: Object of type ndarray is not JSON serializable

please tell me is there any solution? or it is just deepface's bug?

CodePudding user response：

you have to pass the image directly. No need to read with opencv & then pass to Deepface.analyze. Read documentaion clearly.

backends = ['opencv', 'ssd', 'dlib', 'mtcnn', 'retinaface', 'mediapipe']
analyze = DeepFace.analyze(img_path = 'emotion.jpg', detector_backend =backends[4])
print(analyze)
