## [Open Model Zoo automation tools](https://github.com/openvinotoolkit/open_model_zoo/blob/master/tools/model_tools/README.md)
### omz_downloader
用于访问预训练深度学习公共模型和英特尔训练模型的集合。

### omz_converter
使用模型优化器将存储在原始深度学习框架格式中的 Open Model Zoo 模型转换为 OpenVINO 中间表示 (IR)。

### omz_quantizer
用于使用训练后优化工具（Post-Training Optimization Tool）将 IR 格式的全精度模型自动量化为低精度版本。

### omz_info_dumper
用于将有关模型的信息转储为机器可读格式。

### omz_data_downloader
数据集下载器

## 查看可用的模型
Open Model Zoo 自动化工具都可以使用参数 ```--print_all```
```shell
$ omz_tool --print_all
```
```
