Recently, I optimize my YOLO project:

https://github.com/yjh0410/PyTorch_YOLO-Family

On the COCO-val:

A new version YOLO-Nano inspired by NanoDet.

In this project, you can enjoy:

• a different version of YOLO-Nano

This is a a different of YOLO-Nano built by PyTorch:

• Backbone: ShuffleNet-v2
• Neck: a very lightweight FPN+PAN

• Batchsize: 32
• Base lr: 1e-3
• Max epoch: 120
• LRstep: 60, 90
• optimizer: SGD

The overview of my YOLO-Nano

Environment:

• Python3.6, opencv-python, PyTorch1.1.0, CUDA10.0,cudnn7.5
• For training: Intel i9-9940k, RTX-2080ti

VOC:

YOLO-Nano-1.0x:

COCO:

YOLO-Nano-0.5x:

On COCO-val

The overview of my YOLO-Nano

• Pytorch-gpu 1.1.0/1.2.0/1.3.0
• Tensorboard 1.14.
• opencv-python, python3.6/3.7

I copy the download files from the following excellent project: https://github.com/amdegroot/ssd.pytorch

I have uploaded the VOC2007 and VOC2012 to BaiDuYunDisk, so for researchers in China, you can download them from BaiDuYunDisk:

You will get a VOCdevkit.zip, then what you need to do is just to unzip it and put it into data/. After that, the whole path to VOC dataset is data/VOCdevkit/VOC2007 and data/VOCdevkit/VOC2012.

# specify a directory for dataset to be downloaded into, else default is ~/data/
sh data/scripts/VOC2007.sh # <directory>

# specify a directory for dataset to be downloaded into, else default is ~/data/
sh data/scripts/VOC2012.sh # <directory>

I copy the download files from the following excellent project: https://github.com/DeNA/PyTorch_YOLOv3

Just run sh data/scripts/COCO2017.sh. You will get COCO train2017, val2017, test2017.

python train.py -d voc --cuda -v [select a model] -ms

You can run python train.py -h to check all optional argument.

python train.py -d coco --cuda -v [select a model] -ms

python test.py -d voc --cuda -v [select a model] --trained_model [ Please input the path to model dir. ]

python test.py -d coco-val --cuda -v [select a model] --trained_model [ Please input the path to model dir. ]

python eval.py -d voc --cuda -v [select a model] --train_model [ Please input the path to model dir. ]

To run on COCO_val:

python eval.py -d coco-val --cuda -v [select a model] --train_model [ Please input the path to model dir. ]

To run on COCO_test-dev(You must be sure that you have downloaded test2017):

python eval.py -d coco-test --cuda -v [select a model] --train_model [ Please input the path to model dir. ]

You will get a .json file which can be evaluated on COCO test server.
