# CV Backbones (including GhostNet, TinyNet, etc.)

**News** 

2020/11/10 The code of TinyNet (NeurIPS 2020) has been release at [MindSpore Model Zoo](https://gitee.com/mindspore/mindspore/tree/master/model_zoo/research/cv/tinynet).

2020/10/31 GhostNet+TinyNet achieves better performance. See details in our NeurIPS 2020 paper: [arXiv](https://arxiv.org/abs/2010.14819).

2020/09/24 We release GhostNet models for more vision tasks on [MindSpore Hub](https://www.mindspore.cn/resources/hub) and [MindSpore Model Zoo](https://gitee.com/mindspore/mindspore/tree/master/model_zoo/research/cv).

2020/06/10 GhostNet is included in [PyTorch Hub](https://pytorch.org/hub/pytorch_vision_ghostnet/).

## GhostNet Code

This repo provides **pretrained models** and **inference code** for TensorFlow and PyTorch:
- Tensorflow: [./ghostnet_tensorflow](https://github.com/huawei-noah/CV-backbones/tree/master/ghostnet_tensorflow) with pretrained model.
- PyTorch: [./ghostnet_pytorch](https://github.com/huawei-noah/CV-backbones/tree/master/ghostnet_pytorch) with pretrained model.
- We also opensource code on [MindSpore Hub](https://www.mindspore.cn/resources/hub) and [MindSpore Model Zoo](https://gitee.com/mindspore/mindspore/tree/master/model_zoo/research/cv).

For **training**, please refer to [tinynet](https://gitee.com/mindspore/mindspore/tree/master/model_zoo/research/cv/tinynet) or [timm](https://rwightman.github.io/pytorch-image-models/training_hparam_examples/#mobilenetv3-large-100-75766-top-1-92542-top-5).
