| | | ##### Pre-trained models for different cfg-files can be downloaded from (smaller -> faster & lower quality): |

| | | * `yolo.cfg` (194 MB COCO-model) - require 4 GB GPU-RAM: http://pjreddie.com/media/files/yolo.weights |
|---|
| | |
|---|
| | | |
|---|
| | | ##### How to use on the command line: |
|---|
| | | |
|---|
| | | On Linux use `./darknet` instead of `darknet.exe`, like this: `./darknet detector test data/coco.data yolo.cfg yolo.weights` |
|---|
| | | On Linux use `./darknet` instead of `darknet.exe`, like this:`./darknet detector test ./cfg/coco.data ./cfg/yolo.cfg ./yolo.weights` |
|---|
| | | |
|---|
| | | * 194 MB COCO-model - image: `darknet.exe detector test data/coco.data yolo.cfg yolo.weights -i 0 -thresh 0.2` |
|---|
| | | * Alternative method 194 MB COCO-model - image: `darknet.exe detect yolo.cfg yolo.weights -i 0 -thresh 0.2` |
|---|
| | |
|---|
| | | * `OPENCV=1` to build with OpenCV 3.x/2.4.x - allows to detect on video files and video streams from network cameras or web-cams |
|---|
| | | * `DEBUG=1` to bould debug version of Yolo |
|---|
| | | * `OPENMP=1` to build with OpenMP support to accelerate Yolo by using multi-core CPU |
|---|
| | | * `LIBSO=1` to build a library `darknet.so` and binary runable file `uselib` that uses this library. How to use this SO-library from your own code - you can look at C++ example: https://github.com/AlexeyAB/darknet/blob/master/src/yolo_console_dll.cpp |

| | | * `LIBSO=1` to build a library `darknet.so` and binary runable file `uselib` that uses this library. Or you can try to run so `LD_LIBRARY_PATH=./:$LD_LIBRARY_PATH ./uselib test.mp4` How to use this SO-library from your own code - you can look at C++ example: https://github.com/AlexeyAB/darknet/blob/master/src/yolo_console_dll.cpp |

| | | ### How to compile on Windows: |
|---|
| | |
|---|
| | | |
|---|
| | | 1. Train it first on 1 GPU for like 1000 iterations: `darknet.exe detector train data/voc.data yolo-voc.2.0.cfg darknet19_448.conv.23` |
|---|
| | | |
|---|
| | | 2. Then stop and by using partially-trained model `/backup/yolo-voc_1000.weights` run training with multigpu (up to 4 GPUs): `darknet.exe detector train data/voc.data yolo-voc.2.0.cfg yolo-voc_1000.weights -gpus 0,1,2,3` |
|---|
