#PS1 CROWD DETECTION IN THE CAFETERIA
'''
From imageAI API, we import Object detection and use it to detect the object classes in the image
'''

from imageai.Detection import ObjectDetection
import os
#os.getcwd gets the current working directory of the image
execution_path = os.getcwd()

detector = ObjectDetection()
detector.setModelTypeAsRetinaNet()
detector.setModelPath( os.path.join(execution_path , "resnet50_coco_best_v2.0.1.h5"))
detector.loadModel()
detections = detector.detectObjectsFromImage(input_image=os.path.join(execution_path , "image4.jpg"), output_image_path=os.path.join(execution_path , "imagenew4.jpg"))

for eachObject in detections:
	print(eachObject["name"] + " : " + eachObject["percentage_probability"] )

Does it work? Coz I tried to detect people with the image but it's throwing me below mentioned error.
