alianse777 / darknet-rust Goto Github PK

Hi, thanks for creating these bindings! I wanted to run a darknet network on an OpenGL texture which I already have in GPU memory, so the round-trip from GPU to CPU and back was a bit heavy for me (as well as the CPU operations to put the image into the right format that darknet expects).

I have a prototype working, but I'm not sure how best to contribute it, and I want to know if it's desired from others or not.

This repo points to a somewhat old version of darknet (04b0b15), but I made my modifications based on that commit. If we were to create new bindings, we would either have to point this repo's submodule to a fork which contains the OpenGL code, or merge the OpenGL work upstream and base it on the latest master branch. In that case, the bindings here would probably need to be updated and it could potentially be more work than expected.

What would you recommend I do?

After all that, the higher level darknet crate would then need to be modified with new functions to support running the network from a texture, but that part is pretty easy.

Hi,

I'm trying to construct an image for the darknet model inference.

But I'm not sure if the sequence of the raw image data for the darknet input is RGB or BGR.

And is the range of the pixel value [0.0, 1.0] or [0, 255]

// Create an empty image
let dimg = unsafe { darknet_sys::make_image(640, 480, 3) };

// Fill the data with RGB ranging from [0, 1]
let slice = unsafe { slice::from_raw_parts_mut(dimg.data, 640*480*3) }; 
for i in 0..640*480*3 {
    slice[i] = v.data[i] as f32 / 255.0;
}

// let d_img = unsafe { darknet_sys::resize_image(dimg, 416, 416) };

let img = darknet::Image {
    image: d_img
};

// Make prediction
let detections = net.lock().unwrap().predict(&img, 0.25, 0.5, 0.45, true);

Thanks for your help.

Hi, when I try to build the yolo v3 example file, the thread panics. The error I get is Cannot open include file: 'sys/time.h': No such file or directory [C:\Users\Filip Mattsson\Downloads\rust-darknet\target\debug\build\darknet-sys-2b3d282f1cd2812c\out\build\darknet.vcxproj].

Is there any solution to this issue?

Description:

I am encountering a build failure when trying to use the darknet-rust crate in combination with the opencv crate in my Rust project on Arch Linux. The project builds fine when either crate is used independently, but combining them leads to a build error related to libclang.

Environment:

• OS: Arch Linux - 6.5.9-arch2-1
• Rust version: 1.73.0
• clang version: 16.0.6
• darknet-rust version: 0.4
• opencv version: 0.85.3

Steps to Reproduce:

1. Create a new Rust project.
2. Add darknet-rust and opencv to Cargo.toml.
3. Run cargo build.

Error Log:

=== Detected OpenCV module header dir at: /usr/include/opencv4/opencv2
=== Found OpenCV version: [version] in headers located at: /usr/include/opencv4
=== Generating code in: [...]/test_darknet/target/debug/build/opencv-[hash]/out

=== Using OpenCV headers from: /usr/include/opencv4
thread 'main' panicked at [...]/.cargo/registry/src/index.crates.io-[hash]/clang-sys-1.6.1/src/lib.rs:1735:1:
a `libclang` shared library is not loaded on this thread
note: run with `RUST_BACKTRACE=1` environment variable to display a backtrace
warning: build failed, waiting for other jobs to finish...

Troubleshooting Steps:

• Set LIBCLANG_PATH to /usr/lib.
• Tried different versions of the crates.
• Installed libclang and verified its presence.

Any help or guidance on resolving this issue would be greatly appreciated.
