# #The hb_model_info Tool

The `hb_model_info` tool is used to parse the dependencies and parameters of the *.hbm, the *.bc in compilation and the basic information of the *.onnx model, at the same time support the checking of *.bc deletable nodes, and you can view the model structure by starting the webserver.

## #Support Range

It supports viewing the basic information of *.onnx models, the dependencies and parameters information of *.bc model, the information of deletable nodes, as well as the dependencies and parameters information of *.hbm model.

## #Usage

`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`

## #Parameters Introduction

Parameter Name | Parameter Description
`-h, --help` | Display help information and exit.
`--version` | Display version information and exit.
`-v, --visualize` | Start netron server to view the model structure, you can close it with `Ctrl+C` when you finish viewing.

## #Usage Example

Taking the `resnet50_224x224_nv12.hbm` model as an example, you can refer to the following command to view the model compilation information:

`hb_model_info ./model_output/resnet50_224x224_nv12.hbm`

## #Output Contents

The output includes some input information during model compilation, as well as memory usage information occupied when the model is deployed and run on the board, as shown below:

Note

The version number information and other content in the following code block will change with the release package version, and here is only as an example.
