There is a bug in the compilation it

Tried to compilation YOLOv5_Torchscript: libtorch-cu101 cd YOLOv5_Torchscript mkdir -p build &&build cmake .. -- The C compiler identification is GNU 7.5.0 -- The CXX compiler identification is GNU 7.5.0 -- Check for working C compiler: /usr/bin/cc -- Check for working C compiler: /usr/bin/cc -- works -- Detecting C compiler ABI info -- Detecting C compiler ABI info - done -- Detecting C compile features -- Detecting C compile features - done -- Check for working CXX compiler: /usr/bin/c++ -- Check for working CXX compiler: /usr/bin/c++ -- works -- Detecting CXX compiler ABI info -- Detecting CXX compiler ABI info - done -- Detecting CXX compile features -- Detecting CXX compile features - done -- Looking for pthread.h -- Looking for pthread.h - found -- Performing Test CMAKE_HAVE_LIBC_PTHREAD -- Performing Test CMAKE_HAVE_LIBC_PTHREAD - Failed -- Looking for pthread_create in pthreads -- Looking for pthread_create in pthreads - not found -- Looking for pthread_create in pthread -- Looking for pthread_create in pthread - found -- Found Threads: TRUE

Thanks !

Like what said in the error, cmake found cuda9.1 but u use cuda10.1. I think u need to fix ur code in cmakelist and set path for cuda.

Hi,zherlock030 Set path for cuda in your cmakelist
set(CUDA_DIR "/usr/local/cuda-10.1/target/") find_package(CUDA QUIET)

Tried to compilation a build ,some issues . Could you build a yolov5-torchscript with gpu cuda libtorch . Thanks you!

hi @molyswu Sorry I do not have the environment to build that. I think maybe u could refer to https://github.com/yasenh/libtorch-yolov5.

Hi@zherlock030 compiled the build is OK, tried to run ./libtorch-yolov5
./libtorch-yolov5 ../weights/yolov5s_last.pt ~/Documents/data/valid/2014.jpg -gpu Error loading the model!

Could you provide more detailed information? What error when loading the model?
