hi,professor:
i compile your example code nanotrack-macos, i got an error:
error: ‘class ncnn::Extractor’ has no member named ‘opt’
ex_backbone.opt.use_vulkan_compute = true;
why got this compile error?
i use ncnn-20220420-full-source.zip, ncnn is compile from this source code.
please HELP!

林哥你好，我是ubuntu的系统，那么这行命令应该怎么修改呢：cmake -DCMAKE_SYSTEM_PROCESSOR=arm64 -DCMAKE_OSX_ARCHITECTURES=arm64 .. \

@HonglinChu 你好，我在虚拟机上运行提供的程序，把ncnn替换成我自己编译好的静态库和头文件，opencv是4.6版本。当我进行测试跟踪车时，出现上面说的情况，下面是我保存的跟踪视频：

我们按照代码重新训练了这个算法，但是通过vot2019 测试之后效果远差于代码中提供的pth模型，能否提供训练所使用的参数？

nanotrack_backbone_X255.pt and nanotrack_backbone_T127.pt，how to convert them to nanotrack_backbone_sim-opt.bin and nanotrack_backbone_sim-opt.param?
How to convert two pt files into one bin and param files?

你好,请问有没有参数能判断当前跟踪目标置信度多少

hi,professor:
i fllow your code, and try convert to tensorrt code, i convert backbone net to onnx format ok, i use netron , then input size is

,but i debug your ncnn-macos code, i find code below:
ncnn::Mat ncnn_img = ncnn::Mat::from_pixels(z_crop.data, ncnn::Mat::PIXEL_BGR2RGB, z_crop.cols, z_crop.rows);
printf("ncnn_img.w:%d,ncnn_img.h:%d\n",ncnn_img.w,ncnn_img.h);
the result is ncnn_img.w=127, ncnn_img.h=127;
so, what the real size for backbone input node??
how can i deal with this problem?
PLEASE HELP!
