tensorflow-lite-yolo-v3

Convert the weights of YOLO v3 object detector into tensorflow(.pb) or tensorflow lite format. It can be served for tensorflow serving as well.

How to run

1. Download COCO class names file: wget https://raw.githubusercontent.com/pjreddie/darknet/master/data/coco.names
2. Download binary file with desired weights:
   • Full weights: wget https://pjreddie.com/media/files/yolov3.weights
   • Tiny weights: wget https://pjreddie.com/media/files/yolov3-tiny.weights
   • SPP weights: wget https://pjreddie.com/media/files/yolov3-spp.weights
3. Convert .weights to .pb saved_model python ./convert_weights_pb.py (this can be used for tensorflow serving)
4. Convert .pb to .tflite tflite_convert --saved_model_dir=saved_model/ --output_file yolo_v3.tflite --saved_model_signature_key='predict'

Optional Flags

--class_names
    Path to the class names file
--weights_file
    Path to the desired weights file    
--data_format
    `NCHW` (gpu only) or `NHWC`
--tiny
    Use yolov3-tiny
--spp
    Use yolov3-spp
--output_graph
    Location to write the output .pb graph
