Thanks for your code! Following your instruction, I encounter errors when make: just a lot of stuff and I paste some of that:

What should I do with this? Many thx!

Probably I should set something relating to CMake myself but I am not very good at it. Could you give me some suggestions or where I should modify?

zbw4034 commented 6 years ago

The author's code is compiled on TX2,which is aarch64,you should check cmakelists.txt and cmakeprebuild.sh carefully and make some changes

claudehang commented 6 years ago

Oh thank you! I am not aware of that at all. But could you explain it a little bit more in detail if possible? Which I should modify and which is not even necessary for a Linux PC? I am really overwhelmed at it. Best regards!

claudehang commented 6 years ago

I test some parts of the code and come across the problem relating to CUDA.

In cuda.cpp, when I run the function: float cuda_make_array(float x, size_t n) it reports "an illeagal memory access was encountered" error at line: status = cudaMemcpy(x_gpu, x, size, cudaMemcpyHostToDevice);

I've checked that x is accessible but when access x_gpu[0] it reports segmentation fault. What might I check further to find out the devil? Any advice would be greatly appreciated!

Hi, I've got the same problem, have you solved it? Could you please tell me how to modify the cmakelists.txt? Thanks

its may be about the system environment, I have successfully installed this project on centos7 system with GPU 2080ti. Go to https://github.com/passion3394/darknet2caffe_yolov3
