COCO 的圖片資料集,提供3種標注檔:object instances(用於物件偵測), person keypoints(人的關鍵點,用於姿態識別)以及 image captions(圖像標題, 5 captions per image) , 每種標注類型都有相應的json 檔。標注檔也分好了訓練集、驗證集。
with open(annotation_file, "r") as f:
data = json.load(f)
annotations=data["annotations"]
images=data["images"]
categories=data["categories"]
print(f"Number of images: {len(annotations)}")
print(f"Number of images: {len(images)}")
print(f"Number of images: {len(categories)}")

When darkflow sees you are loading tiny-yolo-voc.weights it will look for tiny-yolo-voc.cfg in your cfg/ folder and compare that configuration file to the new one you have set with --model cfg/tiny-yolo-voc-3c.cfg. In this case, every layer will have the same exact number of weights except for the last two, so it will load the weights into all layers up to the last two because they now contain different number of weights.
