Hello and thanks for reading this.
I’ve been using Torchscrip for a C++ projet for 1 month now. I don’t know what i’ve done but suddenty i can’t execute my code. I have created another small project simpler for this topic.
Here is my cmake
cmake_minimum_required(VERSION 3.0)
project(aanet)
# add_definitions(-D_GLIBCXX_USE_CXX11_ABI=0)
set(CMAKE_CXX_FLAGS "-D_GLIBCXX_USE_CXX11_ABI=0")
set(Torch_DIR ${CMAKE_SOURCE_DIR}/libtorch/share/cmake/Torch)
find_package(Torch REQUIRED)
add_executable(${PROJECT_NAME} main.cpp)
target_link_libraries(${PROJECT_NAME} "${TORCH_LIBRARIES}")
set_property(TARGET ${PROJECT_NAME} PROPERTY CXX_STANDARD 14)
my code
#include <torch/torch.h>
#include <iostream>
int main() {
torch::Tensor tensor = torch::rand({2, 3});
std::cout << tensor << std::endl;
}
cmake …

I tested all the version of libtorch and all have the same problem.
I would be very grateful if someone can help me. I am blocked for 2 days on this and i m totally lost.
Thank you 
!
