new-YOLOv1_PyTorch

In this project, you can enjoy:

• a new version of yolov1

Network

This is a a new version of YOLOv1 built by PyTorch:

• Backbone: resnet18
• Head: SPP, SAM

Train

• Batchsize: 32
• Base lr: 1e-3
• Max epoch: 160
• LRstep: 60, 90
• optimizer: SGD

Before I tell you how to use this project, I must say one important thing about difference between origin yolo-v2 and mine:

• For data augmentation, I copy the augmentation codes from the https://github.com/amdegroot/ssd.pytorch which is a superb project reproducing the SSD. If anyone is interested in SSD, just clone it to learn !(Don't forget to star it !)

So I don't write data augmentation by myself. I'm a little lazy~~

My loss function and groundtruth creator both in the tools.py, and you can try to change any parameters to improve the model.

Dataset

As for now, I only train and test on PASCAL VOC2007 and 2012.

VOC Dataset

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:

Password：4la9

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
• data/VOCdevkit/VOC2012.

Download VOC2007 trainval & test

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

Download VOC2012 trainval

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

MSCOCO Dataset

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

Download MSCOCO 2017 dataset

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

• data/COCO/annotations/
• data/COCO/train2017/
• data/COCO/val2017/
• data/COCO/test2017/

Train

VOC

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

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

COCO

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

Test

VOC

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

COCO

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

Evaluation

VOC

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

COCO

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.
