This is the code

from imageai.Detection import VideoObjectDetection
import os

execution_path = os.getcwd()

detector = VideoObjectDetection()
detector.setModelTypeAsRetinaNet()
detector.setModelPath(os.path.join(execution_path, "resnet50_coco_best_v2.0.1.h5"))

custom_objects = detector.CustomObjects(car=True, motorcycle=True, truck=True)

video_path = detector.detectCustomObjectsFromVideo(
            custom_objects=custom_objects,
            input_file_path=os.path.join(execution_path, "cars.avi"),
            save_detected_video=False,
            frames_per_second=30,
            log_progress=True)

print(video_path)

and this is the error

An error occured. It may be that your input video is invalid. Ensure you specified a proper string value for 'output_file_path' is 'save_detected_video' is not False. "
