#hb_model_info工具
hb_model_info 是用于解析*.hbm和*.bc编译时的依赖及参数信息、*.onnx模型基本信息，同时支持对*.bc可删除节点进行查询的工具，可通过启动webserver以查看模型结构。
#支持范围
支持查看 *.onnx模型基本信息，*.bc模型的依赖及参数信息、可删除节点信息，*.hbm模型的依赖及参数信息。
#使用方法
Usage: hb_model_info [OPTIONS] MODEL_PATH
A tool to get info about model compilation parameters, properties
Options:
-h, --help Show this message and exit.
--version Show the version and exit.
-v, --visualize Start netron server to show model structure#命令行参数
| 参数名称 | 参数说明 |
|---|---|
-h, --help | 显示帮助信息。 |
--version | 显示版本并退出。 |
-v, --visualize | 启动webserver以查看模型结构，查看完毕后可使用 Ctrl+C 关闭。 |
#使用示例
以resnet50_224x224_nv12.hbm模型为例，使用以下命令查看模型编译信息：
hb_model_info ./model_output/resnet50_224x224_nv12.hbm#输出内容说明
输出部分包括模型编译时的一些输入信息，以及模型上板运行时会占用的内存信息，如下所示：
