* ***Yolo-Fastest： Faster and stronger https://github.com/dog-qiuqiu/Yolo-Fastest***
* ***此表中NCNN基准未更新最新ARM82数据，最新版本NCNN理论上ARM82会有一倍速度提升，待更新...***
* 添加基于ncnn的106关键点 C sample:https://github.com/dog-qiuqiu/MobileNet-Yolo/tree/master/sample/ncnn
## ***Darknet Group convolution is not well supported on some GPUs such as NVIDIA PASCAL!!! 
* https://github.com/AlexeyAB/darknet/issues/6091#issuecomment-651667469
## 针对某些Pascal显卡例如1080ti在darknet上 训练失败/训练异常缓慢/推理速度异常 的可以采用Pytorch版yolo3框架 训练/推理

## Reference&Framework instructions&How to Train
* https://github.com/AlexeyAB/darknet
* You must use a pre-trained model to train your own data set. You can make a pre-trained model based on the weights of COCO training in this project to initialize the network parameters

## DarkNet2Caffe tutorial
### Environmental requirements

* Python2.7
* python-opencv
* Caffe(add upsample layer https://github.com/dog-qiuqiu/caffe)
* You have to compile cpu version of caffe！！！
  ```
	cd darknet2caffe/
	python darknet2caffe.py MobileNetV2-YOLOv3-Nano-voc.cfg MobileNetV2-YOLOv3-Nano-voc.weights MobileNetV2-YOLOv3-Nano-voc.prototxt MobileNetV2-YOLOv3-Nano-voc.caffemodel
	cp MobileNetV2-YOLOv3-Nano-voc.prototxt sample
	cp MobileNetV2-YOLOv3-Nano-voc.caffemodel sample
	cd sample
	python detector.py
  ```
### MNN conversion tutorial
* Benchmark:https://www.yuque.com/mnn/cn/tool_benchmark
* Convert darknet model to caffemodel through darknet2caffe
* Manually replace the upsample layer in prototxt with the interp layer
* Take the modification of MobileNetV2-YOLOv3-Nano-voc.prototxt as an example
```
	#layer {
	#    bottom: "layer71-route"
	#    top: "layer72-upsample"
	#    name: "layer72-upsample"
	#    type: "Upsample"
	#    upsample_param {
	#        scale: 2
	#    }
	#}
	layer {
	    bottom: "layer71-route"
	    top: "layer72-upsample"
	    name: "layer72-upsample"
	    type: "Interp"
	    interp_param {
		height:20  #upsample h size
		width:20   #upsample w size
	    }
	}

```
