我得到的输出:
我试图打印与模型所做注释关联的类
因此,输出应该如下所示(给定“Dog”在“category_index”中有索引1):
或
我面临的主要问题是,我无法找出如何从“类”中为相应的得分>0.5的元素编制索引
可视化\u图像\u阵列上的\u框\u和\u标签\u
功能如下:
类
可以像框
s_class = classes[scores > 0.5]
print(s_class)
对于对象检测iPynb中的第一个示例,将返回[18.18.]
。18对应于类别索引中的狗

可以类似于框
s_class = classes[scores > 0.5]
print(s_class)

s_class = classes[scores > 0.5]
print(s_class)
