| | | ### How to compile: |
| | | |
| | | 1. If you have CUDA 8.0, OpenCV 2.4.9 (C:\opencv_2.4.9) and MSVS 2015 then start MSVS, open `build\darknet\darknet.sln` and do the: Build -> Build darknet |
| | | 1. If you have MSVS 2015, CUDA 8.0 and OpenCV 2.4.9 (with paths: `C:\opencv_2.4.9\opencv\build\include` & `C:\opencv_2.4.9\opencv\build\x64\vc14\lib`), then start MSVS, open `build\darknet\darknet.sln`, set **x64** and **Release**, and do the: Build -> Build darknet |
| | | |
| | | 1.1 If you want to build with CUDNN to speed up, then: |
| | | |
| | | * download and install CUDNN: https://developer.nvidia.com/cudnn |
| | | |
| | | * add Windows system variable `cudnn` with path to CUDNN: https://hsto.org/files/a49/3dc/fc4/a493dcfc4bd34a1295fd15e0e2e01f26.jpg |
| | | |
| | | * open `\darknet.sln` -> (right click on project) -> properties -> C/C++ -> Preprocessor -> Preprocessor Definitions, and add at the beginning of line: `CUDNN;` |
| | | |
| | | |
| | | 2. If you have other version of CUDA (not 8.0) then open `build\darknet\darknet.vcxproj` by using Notepad, find 2 places with "CUDA 8.0" and change it to your CUDA-version, then do step 1 |
| | | |
| | |
| | | - (right click on project) -> properties -> C/C++ -> General -> Additional Include Directories, put here: |
| | | |
| | | `C:\opencv_2.4.9\opencv\build\include;..\..\3rdparty\include;%(AdditionalIncludeDirectories);$(CudaToolkitIncludeDir);$(cudnn)\include` |
| | | - right click on project -> Build dependecies -> Build Customizations -> set check on CUDA 8.0 or what version you have - for example as here: http://devblogs.nvidia.com/parallelforall/wp-content/uploads/2015/01/VS2013-R-5.jpg |
| | | - (right click on project) -> Build dependecies -> Build Customizations -> set check on CUDA 8.0 or what version you have - for example as here: http://devblogs.nvidia.com/parallelforall/wp-content/uploads/2015/01/VS2013-R-5.jpg |
| | | - add to project all .c & .cu files from `\src` |
| | | - (right click on project) -> properties -> Linker -> General -> Additional Library Directories, put here: |
| | | - (right click on project) -> properties -> Linker -> General -> Additional Library Directories, put here: |
| | | |
| | | `C:\opencv_2.4.9\opencv\build\x64\vc12\lib;$(CUDA_PATH)lib\$(PlatformName);$(cudnn)\lib\x64;%(AdditionalLibraryDirectories)` |
| | | - (right click on project) -> properties -> Linker -> Input -> Additional dependecies, put here: |
| | |
| | | `..\..\3rdparty\lib\x64\pthreadVC2.lib;cublas.lib;curand.lib;cudart.lib;cudnn.lib;%(AdditionalDependencies)` |
| | | - (right click on project) -> properties -> C/C++ -> Preprocessor -> Preprocessor Definitions |
| | | |
| | | - open file: `\src\yolo.c` and change 3 lines to your OpenCV-version - `249` (for 2.4.9), `2413` (for 2.4.13), ... : |
| | | |
| | | * `#pragma comment(lib, "opencv_core249.lib")` |
| | | * `#pragma comment(lib, "opencv_imgproc249.lib")` |
| | | * `#pragma comment(lib, "opencv_highgui249.lib")` |
| | | |
| | | `OPENCV;_TIMESPEC_DEFINED;_CRT_SECURE_NO_WARNINGS;GPU;WIN32;NDEBUG;_CONSOLE;_LIB;%(PreprocessorDefinitions)` |
| | | - compile to .exe (X64 & Release) and put .dll-s near with .exe: |
| | | |
| | |
| | | |
| | | 8. Start training by using the command line: `darknet.exe detector train data/obj.data yolo-obj.cfg darknet19_448.conv.23` |
| | | |
| | | 9. After training is complete - get result `yolo-obj_final.weights` from path `build\darknet\x64\backup\` |
| | | |
| | | * Also you can get result earlier than all 45000 iterations, for example, usually sufficient 2000 iterations for each class(object). I.e. for 6 classes to avoid overfitting - you can stop training after 12000 iterations and use `yolo-obj_12000.weights` to detection. |
| | | |
| | | ### Custom object detection: |
| | | |
| | | Example of custom object detection: `darknet.exe detector test data/obj.data yolo-obj.cfg yolo-obj_3000.weights` |
