使用 cuda 10.0、ubuntu 18.04 编译 tvm 时出现 cudnn 7 冲突问题

Question

我正在使用 ubuntu 18.04 (x64)，我安装了 cuda 10.0 和 cudnn 7.6（按照 Nvidia 的建议）以及 nvidia 驱动程序 410。我正在尝试使用 cuda 构建 tvm-7.0，但出现以下错误：

    -- Configuring done
CMake Warning at CMakeLists.txt:272 (add_library):
  Cannot generate a safe runtime search path for target tvm_topi because
  files in some directories may conflict with libraries in implicit
  directories:

    runtime library [libcudnn.so.7] in /usr/lib/x86_64-linux-gnu may be hidden by files in:
      /usr/local/cuda-10.0/lib64

  Some of these libraries may not be found correctly.

我不知道这个问题。

该问题不会产生任何错误来停止安装。有来自先前安装的 cudnn 的库。要解决警告，只需转到 /usr/lib/x86_64-linux-gnu 并删除 libcudnn.so.7 即可。
