标签关系见test内的文件,使用方法如下，以及标签对应描述信息如 Tag 查询

from dataloader import DataLoad

a = DataLoad(root_path, image_shape = image_shape)
a.set_gan()
for i in a:
    img, gt = i
    break

plt.imshow(img[0].numpy())
plt.show()
print("label:", gt)

# 查询
name_id = 0 # 0- 13
class_name = a.data_key[name_id]
print(f"class name: {class_name}, info: {a.gt_index2name_dict[name_id][np.argmax(gt[name_id]).item()]}")
