如何重新安装cudnn?

问题描述

安装Cudnn.4.0.4后，我发现是否要运行已下载的代码，需要一个更高版本的Cudnn.然后我下载cudnn-7.0-linux-x64-v4.0-prod.tgz并按以下顺序直接安装:

After install Cudnn.4.0.4, I find if I want to run the code I have downloaded, I need a higher version of Cudnn. Then I download cudnn-7.0-linux-x64-v4.0-prod.tgz and directly install by following order:

 $ sudo cp include/cudnn.h /usr/local/include
 $ sudo cp lib64/libcudnn.* /usr/local/lib
 $ sudo ln -sf /usr/local/lib/libcudnn.so.4.0.7 /usr/local/lib/libcudnn.so.4
 $ sudo ln -sf /usr/local/lib/libcudnn.so.4 /usr/local/lib/libcudnn.so
 $ sudo ldconfig -v

当我运行sudo ldconfig -v时，出现错误:

While I running sudo ldconfig -v, there is an error:

在重新安装cudnn之前，我再次运行源代码并遇到相同的错误:

I run the source code again and have the same error before I reinstall cudnn:

 luajit: /home/zhfu/torch/install/share/lua/5.1/cudnn/ffi.lua:1287: These bindings are for version 4005 or above, while the loaded CuDNN is version: 4004
 Are you using an older version of CuDNN?
 stack traceback:
    [C]: in function 'error'
    /home/zhfu/torch/install/share/lua/5.1/cudnn/ffi.lua:1287: in main chunk
    [C]: in function 'require'

    [C]: in function 'require'
    ./main.lua:329: in main chunk
    [C]: at 0x00406670

有人可以帮我解决这个问题吗?

推荐答案

只需删除/usr/local/lib和/usr/local/cuda/lib64中的所有相关文件那对我有用.

Just delete all related files both in /usr/local/lib and in /usr/local/cuda/lib64That's work for me.
