```
[100%] Linking CXX executable libtorch_resnet
/usr/bin/ld: warning: libgfortran-b6d57c85.so.5.0.0, needed by /usr/local/python3.8.5/lib/python3.8/site-packages/torch/lib/../../torch.libs/libopenblasp-r0-56e95da7.3.24.so, not found (try using     -rpath or -rpath-link)
/usr/bin/ld: /usr/local/python3.8.5/lib/python3.8/site-packages/torch/lib/../../torch.libs/libopenblasp-r0-56e95da7.3.24.so: undefined reference to `_gfortran_concat_string@GFORTRAN_8'

collect2: error: ld returned 1 exit status
make[2]: *** [CMakeFiles/libtorch_resnet.dir/build.make:101: libtorch_resnet] Error 1
make[1]: *** [CMakeFiles/Makefile2:83: CMakeFiles/libtorch_resnet.dir/all] Error 2
make: *** [Makefile:91: all] Error 2
```

#### 原因分析

aarch64环境下进行libtorch推理测试，编译时依赖torch.libs/*.so库，需要手动加载。

#### 解决措施

在CMakeLists.txt编译文件中增加torch.libs/*.so库的链接，代码示例如下：

```
set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} ${TORCH_CXX_FLAGS}")

# 在执行模型代码前增加torch.libs/*.so库的链接，请根据实际情况替换以下命令行中的该库的路径
link_directories(/usr/local/python3.8.5/lib/python3.8/site-packages/torch.libs)  

add_executable(libtorch_resnet libtorch_resnet.cpp)
target_link_libraries(libtorch_resnet "${TORCH_LIBRARIES}")
target_link_libraries(libtorch_resnet "${TORCH_NPU_LIBRARIES}")
```
