Inference

tensorflow

from yolov4.tf import YOLOv4

yolo = YOLOv4()

yolo.classes = "coco.names"

yolo.make_model()
yolo.load_weights("yolov4.weights", weights_type="yolo")

yolo.inference(media_path="kite.jpg")

yolo.inference(media_path="road.mp4", is_image=False)

Object detection test jupyter notebook

from yolov4.tf import YOLOv4

yolo = YOLOv4(tiny=True)

yolo.classes = "coco.names"

yolo.make_model()
yolo.load_weights("yolov4-tiny.weights", weights_type="yolo")

yolo.inference(media_path="kite.jpg")

yolo.inference(media_path="road.mp4", is_image=False)

tensorflow lite

from yolov4.tf import YOLOv4

yolo = YOLOv4()

yolo.classes = "coco.names"

yolo.make_model()
yolo.load_weights("yolov4.weights", weights_type="yolo")

yolo.save_as_tflite("yolov4.tflite")

from yolov4.tflite import YOLOv4

yolo = YOLOv4()

yolo.classes = "coco.names"

yolo.load_tflite("yolov4.tflite")
