WIP. PRs are welcome

Port of Darknet YOLO, but via Gorgonia Both YOLOv3 and tiny-YOLOv3 are implemented.

Usage

Navigate to example/yolo-v3 folder and run main.go.

Available flags

go run main.go -h

  -cfg string
        Path to net configuration file (default "../../test_network_data/yolov3-tiny.cfg")
  -image string
        Path to image file for 'detector' mode (default "../../test_network_data/dog_416x416.jpg")
  -mode string
        Choose the mode: detector/training (default "detector")
  -train string
        Path to folder with labeled data (default "../../test_yolo_op_data")
  -weights string
        Path to weights file (default "../../test_network_data/yolov3-tiny.weights")

For testing tiny-yolov3:

go run main.go --mode detector --cfg ../../test_network_data/yolov3-tiny.cfg --weights ../../test_network_data/yolov3-tiny.weights --image ../../test_network_data/dog_416x416.jpg

For testing yolov3:

go run main.go --mode detector --cfg ../../test_network_data/yolov3.cfg --weights ../../test_network_data/yolov3.weights --image ../../test_network_data/dog_416x416.jpg

For training WIP. PRs are welcome:

go run main.go --mode training --cfg ../../test_network_data/yolov3-tiny.cfg --weights ../../test_network_data/yolov3-tiny.weights --image ../../test_network_data/dog_416x416.jpg --train ../../test_yolo_op_data

Weights and configuration

Weights can be downloaded via curl-scripts download_weights_yolo_v3.sh and download_weights_yolo_tiny_v3.sh. Configuration files: yolov3-tiny.cfg and yolov3.cfg
