Training

Download lmdb

Unzip into $caffe_root/

Please check the path exist "$caffe_root\examples\VOC0712\VOC0712_trainval_lmdb" and "$caffe_root\examples\VOC0712\VOC0712_test_lmdb"

Download pre-trained weights , and save at $caffe_root\model\convert

> cd $caffe_root/
> sh train_yolo.sh

Demo

> cd $caffe_root/
> sh demo_yolo_lite.sh

If load success , you can see the image window like this

Future work

• Distillation training
• Openimages training and testing
