darkhelp's Issues

Can I use DarkHelp along with YOLOV4? Can DarkHelp sends the output of YOLOv4 Darknet via tcp/ip?

I have used YOLOv4 Darknet for object detection. I want to send the results of the Detection to C# gui via tcp/ip. Is it possible using DarkHelp? If yes, what procedures should I follow?
Thank You in Advance.

-> WARNING: signal handler called for signal #11

I followed the instructions of building Darkhelp, running Darkhelp from terminal or from the example when it reaches
DarkHelp::NN::predict(), gives segmentation fault:
DarkHelp cfg/coco.names cfg/yolov4-tiny.cfg yolov4-tiny.weights artwork/dog.jpg

-> WARNING: signal handler called for signal #11

however darknet works correctly.

Detected images saved in Temp folder in windows

Is there any option to save the detected images to a specific folder other than temp folder?

Compiling on Rocky Linux

I'm having trouble installing on Rocky Linux (basically CentOS 8). I've installed darknet following your instructions and it's working.

CUDA-version: 11060 (11060), cuDNN: 8.4.0, CUDNN_HALF=1, GPU count: 1  
 CUDNN_HALF=1 
 OpenCV version: 3.4.6

When I try to make DarkMark I get the following issue.

Any help would be very appreciated. I'm trying to get DarkMark installed and from the video it looks amazing!

Thanks!

cannot open source file "DarkHelp.hpp"

I did all steps from readme_windows.txt, generated a Visual Studio solution, but when I build it I see this:

cannot open source file "DarkHelp.hpp" D:\Projects\DarkHelp\src-lib\DarkHelpConfig.cpp

How to fix it?

an classification problem

in AlexeyAB darknet, softmax_layer.c has two layers, softmax_layer and contrastive _layer.
my problem is "how to use contrastive layer in classification?"
if you known. can offer an example cfg file?
thanks

Issue with Inference - Process finished with exit code 134 (interrupted by signal 6: SIGABRT)

I'm running DarkHelp in a C++ application (Through CLion). I am able to conduct detection through video capture but when I attempt to run inference as I get the following error message:

Process finished with exit code 134 (interrupted by signal 6: SIGABRT)

Code:

DarkHelp::Config cfg(config_file, weights_file, names_file );
cfg.enable_tiles = true;
cfg.combine_tile_predictions = true;
cfg.annotation_auto_hide_labels = false;
cfg.annotation_include_duration = true;
cfg.annotation_include_timestamp = false;

DarkHelp::NN nn(cfg)

const auto result = nn.predict(filename);
cv::Mat output = nn.annotate()

I'm using coco names and config file with pretrained YOLOv4 weights.

Any idea what could be causing the issue?

Thanks in advance.

json output with detection for video inference

Hi, first of all thanks for your great work!

I realised that the output.json does not contain detection when running inference on a video. Is that correct? Is there another way to get the detections for each frame?

DarkHelp Crashes when using Single Channel Networks and OpenCV

When using DarkHelp to load a yolov4-tiny single channel network (grayscale images), and configuring it to use OPENCV as a backend, the program crashes. This can fixed be setting the initial dummy matrix sent to the OpenCV constructor with the appropriate matrix type of CV_8UC1, as shown:

Rather than hardcoding, I think it would be best to read the darknet .cfg file to get the number of channels in the network, and use that value to set the matrix type appropriately, similar to what is done immediately above this section of code with regards to the network dimensions.

Both DarkMark and DarkHelp are excellent!

Is DarkHelp compatible with Yolov5?

hey, Is DarkHelp compatible with Yolov5?

Onnx

Is there any way to perform tiling while doing ONNX inference?

yolov7

Hi, @stephanecharette

I am new to darknet and impressed by your c++ DarkHelp very good coverage.

We are using AI for detecting vehicles from intersections . currently using yolov7 and fairy good enough . We want to give a shot and possibly change to c++ . can we use yolov7 models with darknet. ? If now which model you suggest for replacing yolov7e6 ?

We also want to detect small vehicles from 4Mp resolution . tiling looks very good solution for that. detecting and tracking (bytetrack at the moment)

When tiling we are inferencing more than one image per image. so it make slower . However can we doing inference simultaneously (batch) for tiled version ?

std namespace errors while compiling using cmake

I am building a cross-compilation platform using OpenCV 3.4.4, darknet (and its dependencies) and DarkHelp.

DarkHelp dependencies such as magic, tclap etc have been cross-compiled successfully along with OpenCV and darknet. I have tested it on my RPi, the darknet libs and exe works.

When I try to compile Darkhelp,

cmake -DOpenCV_DIR="${RPI_SYSROOT}/usr/local/lib" -DCMAKE_PREFIX_PATH="${RPI_SYSROOT}/usr/local" ..

This is a short part of the error. All the calls to std:: are reported.

While searching for a solution, I found this post

It seems some include<> are done within the namespace{} as I came across multiple forum posts. Let me know if any more information is required to find a solution.

How can I install DarkHelp if I have installed Darknet using Cmake?

I have installed Darknet already using Cmake. Now, how should I install and use DarkHelp?

DarkHelp does not support batch inference

Investigate what would be needed to support batch inference.

See: AlexeyAB/darknet#7541
And: AlexeyAB/darknet#7915

Installing DarkHelp on Docker in Mac Mini M1.

My goal is to install DarkMark. The problem is that I can't install DarkHelp.

What I've did:

Install Darknet

docker pull ubuntu:18.04
docker run -ti --name darkmark ubuntu:18.04 /bin/bash
apt-get update
apt-get install build-essential git libopencv-dev
mkdir ~/src
git clone https://github.com/AlexeyAB/darknet.git
cd darknet

# set LIBSO=1
apt-get install vim
vim Makefile

make
cp libdarknet.so /usr/local/lib/
cp include/darknet.h /usr/local/include/
ldconfig

Install DarkHelp

apt-get install cmake build-essential libtclap-dev libmagic-dev libopencv-dev
cd ~/src
git clone https://github.com/stephanecharette/DarkHelp.git
cd DarkHelp
mkdir build
cd build
cmake -DCMAKE_BUILD_TYPE=Release ..
make

Gtk-ERROR **

I have a problem. When using DarkHelp (example_project).

(example:14081): Gtk-ERROR **: 12:27:51.323: GTK+ 2.x symbols detected. Using GTK+ 2.x and GTK+ 3 in the same process is not supported

Can you support for resolving it?

Duplicate call to fuse_conv_batchnorm() in init()

DarkHelp/src-lib/DarkHelp.cpp

Lines 145 to 147 in c6b05ba

 // what do these 2 calls do? 

 fuse_conv_batchnorm(*nw); 

 calculate_binary_weights(*nw);

load_network_custom already does call fuse_conv_batchnorm() internally, this will call it twice.

CMAKE build issue Windows Server: Cant find FindCUDNN.cmake CUDNNconfig.cmake CUDNN_config.cmake

Trying to install DarkHelp on Windows Server 2019 with GeForce Ge 1660. Have installed OpenCV with DNN , Installed DarkNet as per the Darknet instructions.
All Path variables have been updated ,including for CUDNN and CUDNN_PATH and server restarted.
OpenCV was built from source with DNN.
Darknet is running correctly from the CLI

Now trying to install DarkHelp as per the sequence in readme_windows.txt.

When running:
cmake -DCMAKE_BUILD_TYPE=Release - DCMAKE_TOOLCHAIN_FILE=C:/src/vcpkg/scripts/buildsystems/vcpkg.cmake ..

using the command as above as well as when replicating via CMAKE GUI I get the following error:

CMake Error at C:/src/vcpkg/scripts/buildsystems/vcpkg.cmake:829 (_find_package):
By not providing "FindCUDNN.cmake" in CMAKE_MODULE_PATH this project has
asked CMake to find a package configuration file provided by "CUDNN", but
CMake did not find one.

Could not find a package configuration file provided by "CUDNN" with any of
the following names:

CUDNNConfig.cmake
cudnn-config.cmake

Add the installation prefix of "CUDNN" to CMAKE_PREFIX_PATH or set
"CUDNN_DIR" to a directory containing one of the above files. If "CUDNN"
provides a separate development package or SDK, be sure it has been
installed.

I located the FindCUDNN.cmake file is in several directories: Opencv/cmake darknet/share/, darknet/cmake/modules, vcpkg/ports/
Any idea how to update the configuration to point towards the correct file?
Thanks in advance

Unused Function Error on ARM64 Ubuntu 18.04

Self solved, leaving this here to save time for any others who encounter this. I encountered this error while following the install:

/src/DarkHelp/src-lib/DarkHelp.cpp:729:23: error: unused function
'convert_darknet_image_to_opencv_mat' [-Werror,-Wunused-function]
static inline cv::Mat convert_darknet_image_to_opencv_mat(const image img)
^
1 error generated.
src-lib/CMakeFiles/dh.dir/build.make:75: recipe for target 'src-lib/CMakeFiles/dh.dir/DarkHelp.cpp.o' failed

This error was solved by editing CM_definitions.cmake , changing the line in ELSE() to
ADD_COMPILE_OPTIONS (-Wextra -Wno-unused-parameter )

Additionally, I got an error for sudo dpkg -i darkmark*.deb
[sudo] password for USER:
dpkg: error: cannot access archive 'darkmark*.deb': No such file or directory

which was solved by replacing the file darkmark*.deb with the full filename

Implement tkDNN?

Do you believe it would be viable to implement tkDNN into DarkHelp as an option?

Run on Python

Hi, this work is very great and I would just like to ask if there might be a possible where it can also be ran natively in Python in the future? Thank you so much.

JSON exporting available?

Is there any option to export the detections as JSON file as in darknet output exporting. The results are printed on the command prompt.

Confused about resize aspect ratio training/inferencing

During training, using DarkMark/darknet CUDA on my linux box, I deselected 'resize images' because I didn't want the network to change the aspect ratio of images.... many are smaller than my network dimensions.

Typical small training images: 96 x 32
Network dimensions: 192 x 96 x 1
Network: YoloV4-Tiny

As the training progresses, DarkMark seems to properly utilize darknet to predict annotations on unmarked images. So all is good up to this point.

When I run inferencing on my Windows box, (using darkhelp API, directly with OpenCV/Cuda), I notice that the NN performs very poorly. Digging in, I see that the function DarkHelp::NN::predict_internal_opencv() calls the function fast_resize_ignore_aspect_ratio. If I change that to resize_keeping_aspect_ratio, then the network performs properly. Shouldn't the prediction function maintain the aspect ratio?

Does DarkHelp Implement Image Tiling during Inference?

@stephanecharette I'm exploring image tiling to improve small object detection. I see that DarkHelp and Darkmark has the ability implement image tiling on datasets; but it's not clear to me if Darkmark implements tiling during inference.

Thanks in advance,

Compilation error on Raspberry Pi 4 / CM4 : cannot convert ‘const long long int’ to ‘const time_t’ {aka ‘const long int*’}

I stumbled on this compilation fatal error (output.txt) while trying to compile Darkhelp on Compute Module 4 (armv7l Raspbian).
This error occurred in 2 files : first in DarkHelpServer.cpp and secondly in DarkHelpCli.cpp

I bypassed this error by editing line 230 in DarkHelpServer.cpp and line 1046 in DarkHelpCli.cpp

DarkHelp/src-tool/DarkHelpServer.cpp

Line 230 in 318e33d

const auto lt = std::localtime(&seconds);

DarkHelp/src-tool/DarkHelpCli.cpp

Line 1046 in 318e33d

const auto lt = std::localtime(&seconds);

I wrote in both files:

std::time_t t = seconds;
const auto lt = std::localtime(&t);

Can you check if my update is correct and update these two files if it complies with your code ?

Thank you in advance.

PS : Thank you for your job done on this project, it's incredible how it's easy to use darknet with your help.

Hide label in annotation

Hi,

I use DarkHelp version: 1.4.15-1.
The commit is : 2c0fdbb

I want image detection results without labels and percentages. I read Darkhelp's parameters to do that (https://www.ccoderun.ca/darkhelp/api/Parameters.html). I see there are 2 parameters -o and -p. When I use them, only the -p parameter works. I read that auto hide label available since 2020-07-03 (https://www.ccoderun.ca/darkhelp/api/classDarkHelp_1_1Config.html#a3086f69df165e7be96cd909682b44c54)

This is my command:

Darkhelp config_path weight_path names_path -f 2 --threshold 0.5 -k -l /opt/image_list.txt --outdir /opt/results -Y jpg -j -o true -p false >/opt/abc.log

I also tried –autohide instead of -o . Tried all the true,false,on,off,1,0 but they don't work

You can see that percentage is disappear but the label still there.

I wonder if I am using it incorrectly? Is there any way to hide the label?

Regards,
An
