## 模型结构
RepViT以MobileNetV3-L为base进行算法优化，从一个标准的轻量级CNN开始，结合轻量级vit的架构设计，使得既具备CNN小计算量又具备vit架构的优势。
<div align=center>

## 算法原理
RepViT与其它图像分类算法一样，将图片数据送入模型后，依次通过预处理、特征提取，然后经过全连接层预测出图片类别。

Segment Anything Model (SAM) has shown impressive zero-shot transfer performance for various computer vision tasks recently. However, its heavy computation costs remain daunting for practical applications. MobileSAM proposes to replace the heavyweight image encoder in SAM with TinyViT by employing distillation, which results in a significant reduction in computational requirements. However, its deployment on resource-constrained mobile devices still encounters challenges due to the substantial memory and computational overhead caused by self-attention mechanisms. Recently, RepViT achieves the state-of-the-art performance and latency trade-off on mobile devices by incorporating efficient architectural designs of ViTs into CNNs. Here, to achieve real-time segmenting anything on mobile devices, following, we replace the heavyweight image encoder in SAM with RepViT model, ending up with the RepViT-SAM model. Extensive experiments show that RepViT-SAM can enjoy significantly better zero-shot transfer capability than MobileSAM, along with nearly $10\times$ faster inference speed.

</summary>
Recently, lightweight Vision Transformers (ViTs) demonstrate superior performance and lower latency compared with lightweight Convolutional Neural Networks (CNNs) on resource-constrained mobile devices. This improvement is usually attributed to the multi-head self-attention module, which enables the model to learn global representations. However, the architectural disparities between lightweight ViTs and lightweight CNNs have not been adequately examined. In this study, we revisit the efficient design of lightweight CNNs and emphasize their potential for mobile devices. We incrementally enhance the mobile-friendliness of a standard lightweight CNN, specifically MobileNetV3, by integrating the efficient architectural choices of lightweight ViTs. This ends up with a new family of pure lightweight CNNs, namely RepViT. Extensive experiments show that RepViT outperforms existing state-of-the-art lightweight ViTs and exhibits favorable latency in various vision tasks. On ImageNet, RepViT achieves over 80\% top-1 accuracy with 1ms latency on an iPhone 12, which is the first time for a lightweight model, to the best of our knowledge. Our largest model, RepViT-M2.3, obtains 83.7\% accuracy with only 2.3ms latency.

Tips: Convert a training-time RepViT into the inference-time structure
```
from timm.models import create_model
import utils
model = create_model('repvit_m0_9')
utils.replace_batchnorm(model)
```
## Latency Measurement
The latency reported in RepViT for iPhone 12 (iOS 16) uses the benchmark tool from [XCode 14](https://developer.apple.com/videos/play/wwdc2022/10027/).
For example, here is a latency measurement of RepViT-M0.9:
![](./figures/repvit_m0_9_latency.png)
Tips: export the model to Core ML model
```
python export_coreml.py --model repvit_m0_9 --ckpt pretrain/repvit_m0_9_distill_300e.pth
```
Tips: measure the throughput on GPU
```
python speed_gpu.py --model repvit_m0_9
```
## ImageNet
### Prerequisites
`conda` virtual environment is recommended.
```
conda create -n repvit python=3.8
pip install -r requirements.txt
```
### Data preparation
Download and extract ImageNet train and val images from http://image-net.org/. The training and validation data are expected to be in the `train` folder and `val` folder respectively:
```
|-- /path/to/imagenet/
|-- train
|-- val
```
### Training
To train RepViT-M0.9 on an 8-GPU machine:
```
python -m torch.distributed.launch --nproc_per_node=8 --master_port 12346 --use_env main.py --model repvit_m0_9 --data-path ~/imagenet --dist-eval
```
Tips: specify your data path and model name!
### Testing
For example, to test RepViT-M0.9:
```
python main.py --eval --model repvit_m0_9 --resume pretrain/repvit_m0_9_distill_300e.pth --data-path ~/imagenet
```

# Object Detection and Instance Segmentation
Detection and instance segmentation on MS COCO 2017 is implemented based on [MMDetection](https://github.com/open-mmlab/mmdetection).
## Models
| Model | $AP^b$ | $AP_{50}^b$ | $AP_{75}^b$ | $AP^m$ | $AP_{50}^m$ | $AP_{75}^m$ | Latency | Ckpt | Log |
|:---------------|:----:|:---:|:--:|:--:|:--:|:--:|:--:|:--:|:--:|
| RepViT-M1.1 | 39.8 | 61.9 | 43.5 | 37.2 | 58.8 | 40.1 | 4.9ms | [M1.1](https://github.com/THU-MIG/RepViT/releases/download/v1.0/repvit_m1_1_coco.pth) | [M1.1](./logs/repvit_m1_1_coco.json) |
| RepViT-M1.5 | 41.6 | 63.2 | 45.3 | 38.6 | 60.5 | 41.5 | 6.4ms | [M1.5](https://github.com/THU-MIG/RepViT/releases/download/v1.0/repvit_m1_5_coco.pth) | [M1.5](./logs/repvit_m1_5_coco.json) |
| RepViT-M2.3 | 44.6 | 66.1 | 48.8 | 40.8 | 63.6 | 43.9 | 9.9ms | [M2.3](https://github.com/THU-MIG/RepViT/releases/download/v1.0/repvit_m2_3_coco.pth) | [M2.3](./logs/repvit_m2_3_coco.json) |
## Installation
Install [mmcv-full](https://github.com/open-mmlab/mmcv) and [MMDetection v2.28.2](https://github.com/open-mmlab/mmdetection/tree/v2.28.2),
Later versions should work as well.
The easiest way is to install via [MIM](https://github.com/open-mmlab/mim)
```
pip install -U openmim
mim install mmcv-full==1.7.1
mim install mmdet==2.28.2
```
## Data preparation
Prepare COCO 2017 dataset according to the [instructions in MMDetection](https://github.com/open-mmlab/mmdetection/blob/master/docs/en/1_exist_data_model.md#test-existing-models-on-standard-datasets).
The dataset should be organized as
```
detection
├── data
│ ├── coco
│ │ ├── annotations
│ │ ├── train2017
│ │ ├── val2017
│ │ ├── test2017
```
## Testing
We provide a multi-GPU testing script, specify config file, checkpoint, and number of GPUs to use:
```
./dist_test.sh config_file path/to/checkpoint #GPUs --eval bbox segm
```
For example, to test RepViT-M1.1 on COCO 2017 on an 8-GPU machine,
```
./dist_test.sh configs/mask_rcnn_repvit_m1_1_fpn_1x_coco.py path/to/repvit_m1_1_coco.pth 8 --eval bbox segm
```
## Training
Download ImageNet-1K pretrained weights into `./pretrain`
We provide PyTorch distributed data parallel (DDP) training script `dist_train.sh`, for example, to train RepViT-M1.1 on an 8-GPU machine:
```
./dist_train.sh configs/mask_rcnn_repvit_m1_1_fpn_1x_coco.py 8
```
Tips: specify configs and #GPUs!
