Checkout to stable YOLO v4

[LdDl]

Trying to checkout stable'ish YOLO v4: https://github.com/AlexeyAB/darknet/releases/tag/yolov4

Current state for GPU:

Failed to calloc 17179869184.0 GiB
Darknet error location: ./src/image.c, make_image, line #797
Calloc error - possibly out of CPU RAM: Cannot allocate memory

Need to dig into (Darknet's source code)

image make_image(int w, int h, int c)
{
    image out = make_empty_image(w,h,c);
    out.data = (float*)xcalloc(h * w * c, sizeof(float));
    return out;
}

Current state for CPU:

When make switch from network_predict_ptr() to network_predict()

    // replace network_predict_ptr(n, sized.data); with 
    network_predict(*n, sized.data);

I got same error, but for 'CPU' RAM:

Failed to calloc 17179869184.0 GiB
Darknet error location: ./src/image.c, make_image, line #797
Calloc error - possibly out of CPU RAM: Cannot allocate memory

I guess the problem is in this call:

sized = resize_image(*img, n->w, n->h);

both n->w and n->h give strange output (neither 416 or 608, which depends on *.cfg file): something like 20127904x0

When use

LATEST_COMMIT?=d65909fbea471d06e52a2e4a41132380dc2edaa6

I've got 608x608 for YOLOv4

So, I assume something went wrong on setting networks parameters when use 'stable'-ish release.

Changes between current working commit and stable one: https://github.com/AlexeyAB/darknet/compare/d65909fbea471d06e52a2e4a41132380dc2edaa6...AlexeyAB:9d40b619756be9521bc2ccd81808f502daaa3e9a

Addition: manual setup of width/height in resize_image leads to expected ('good') results without any errors (checked CPU)

I have tried every commit for the last 2 years (starting from commit f056fc3b6a11528fa0522a468eca1e909b7004b7) and I get a compilation error for every single one.

ld: library not found for -l:libdarknet.so
clang: fatal error: linker command failed with exit code 1 (use -v to see invocation)

I am a mac user running make install_darknet for CPU usage of darknet

[LdDl]

I guess you need to make libdarknet.so 'visible' for compiler (also do not forget to make LIBSO=1 in Makefile)
