Applying Morph-net while training training Yolov3 using darknet

can anyone please tell me how to use the morph-net to find the optimized number of filter size for Tiny-yolo-v3 during training using darknet (https://github.com/AlexeyAB/darknet).

I want to optimize the model for latency (that is my regularizer target cost)

Any documentation or information on how to apply morph-net during darknet training will be highly helpful
