FAIL：无法加载库 libonnxruntime_providers_cuda.so，错误：libcudnn.so.8：无法打开共享对象文件：没有这样的文件或目录

Question

terminate called after throwing an instance of 'Ort::Exception'
  what():  /onnxruntime_src/onnxruntime/core/session/provider_bridge_ort.cc:1193 onnxruntime::Provider& onnxruntime::ProviderLibrary::Get() [ONNXRuntimeError] : 1 : FAIL : Failed to load library libonnxruntime_providers_cuda.so with error: libcudnn.so.8: cannot open shared object file: No such file or directory

Signal: SIGABRT (Aborted)

在 CMakeLists.txt 中，我添加了此 lib abs 路径，并且确保此 lib 路径存在

file(GLOB cuda_libs /usr/local/cuda-11.8/lib64/*.so*)
file(GLOB cudnn_libs /home/roroco/Downloads/cpp-lib/cudnn-linux-x86_64-8.9.0.131_cuda11-archive/lib/*.so.*)

set(libs

如何解决

Answer 1

就我而言，我的 /usr/local 不包含 cudnn，我应该将 cudnn lib dir 添加到 LD_LIBRARY_PATH

LD_LIBRARY_PATH=${LD_LIBRARY_PATH}:/home/roroco/Downloads/cpp-lib/cudnn-linux-x86_64-8.9.0.131_cuda11-archive/lib cpp_cmd

在 clion debug conf 中，我可以设置 env var

我认为简单的方法是将

export LD_LIBRARY_PATH=$LIBRARY_PATH:path/to/cudnn/lib/dir

放在 ~/.bashrc 中以在所有 cmd 启动时设置 cudnn lib 目录
