从源代码构建TensorFlow后,看到libcudart.so和libcudnn错误

Question

我正在从源代码构建TensorFlow.构建似乎成功; 但是,当我的TensorFlow程序调用时import tensorflow,会出现以下一个或两个错误:

• ImportError: libcudart.so.8.0: cannot open shared object file: No such file or directory
• ImportError: libcudnn.5: cannot open shared object file: No such file or directory

Answer 1

首先,出现以下错误:

ImportError:libcudart.so.8.0:无法打开共享对象文件:没有这样的文件或目录

确保你在你安装cuda包的路径中LD_LIBRARY_PATH包含你的lib64目录.你可以通过添加export一行代码来完成.bashrc.对于奥马尔来说,它看起来如下:

我修复此问题只是将cuda路径添加到我的.bashrc中

export LD_LIBRARY_PATH=/usr/local/cuda/lib64/

对我来说,我不得不做Omar的路线, export LD_LIBRARY_PATH=/usr/local/cuda-8.0/lib64/ 因为我有两个涉及cuda的目录(可能不是最好的).

其次,你确定你安装了cuDNN吗？请注意,这与常规cuda包不同.您需要注册,然后从以下页面下载并安装软件包:https: //developer.nvidia.com/cudnn

第三,我有同样的问题:

ImportError:libcudnn.5:无法打开共享对象文件:没有这样的文件或目录

事实证明libcudnn.5我/usr/local/cuda/lib64或/usr/local/cuda-8.0/lib64目录中没有.但是,我确实有一个libcudnn.so.6.*文件.为了解决这个问题,我创建了一个软链接:

ln -s libcudnn.so.6.* libcudnn.so.5

在我的/usr/local/cuda/lib64目录中.现在一切都适合我.如果您已经拥有cuDNN,您的目录可能会有所不同,并且您的目录libcudnn.so.6.*可能是不同的版本,因此请检查.

我已经在它需要的时候安装了cudnn 6.0 libcudnn.so.5,显然它无法找到libcudnn.so.5.看来你的张量流需要cudnn 5.x,所以安装cudnn 5.x.

确保您已经安装了cuda 8.0并导出了PATH和LD_LIBRARY_PATH

要安装cudnn 5.x,请尝试以下命令

提取tgz文件

$ tar -zxvf cudnn-8.0-linux-x64-v5.1.tgz

检查文件

$ cd cuda/lib64/
$ ls -l
total 150908
lrwxrwxrwx 1 doom doom       13 Nov  7  2016 libcudnn.so -> libcudnn.so.5
lrwxrwxrwx 1 doom doom       18 Nov  7  2016 libcudnn.so.5 -> libcudnn.so.5.1.10
-rwxr-xr-x 1 doom doom 84163560 Nov  7  2016 libcudnn.so.5.1.10
-rw-r--r-- 1 doom doom 70364814 Nov  7  2016 libcudnn_static.a

在这里你会看到2个符号链接文件,只是复制libcudnn.so.5.1.10和libcudnn_static.a到/usr/local/cuda/lib64

制作符号链接文件

$ cd /usr/local/cuda/lib64/
$ sudo ln -s libcudnn.so.5.1.10 libcudnn.so.5
$ sudo ln -s libcudnn.so.5 libcudnn.so
$ ls -l libcudnn*
lrwxrwxrwx 1 root root       13 May 24 09:24 libcudnn.so -> libcudnn.so.5
lrwxrwxrwx 1 root root       18 May 24 09:24 libcudnn.so.5 -> libcudnn.so.5.1.10
-rwxr-xr-x 1 root root 84163560 May 24 09:23 libcudnn.so.5.1.10
-rw-r--r-- 1 root root 70364814 May 24 09:23 libcudnn_static.a

复制cudnn.h的include目录/usr/local/cuda/include

$ sudo cp cudnn.h /usr/local/cuda/include/

希望它能帮到你!

Answer 3

我修复此问题只是将cuda路径添加到我的.bashrc中

export LD_LIBRARY_PATH=/usr/local/cuda/lib64/

请记住,首先您需要访问nvidia Deep Learning页面,注册并下载cuDNN,将include和lib64文件夹中的文件解压缩并复制到您的cuda安装中.

Answer 4

我看到了类似的错误(这篇文章的底部),但抱怨libcudnn.so.6而不是libcudart.so.8.0(参见下面的注释).

解:

1. 下载' cuDNN v6.0 Library for Linux ':
   • 转到https://developer.nvidia.com/rdp/cudnn-download
   • 点击" 下载cuDNN v6.0(2017年4月27日),CUDA 8.0 "
   • 然后单击" cuDNN v6.0 Library for Linux ".将下载一个文件(名为' cudnn-8.0-linux-x64-v6.0.tgz ').
2. 按照上面 Alexander Yau 的说明安装cuDNN v6.0库.

注意:

Tensorflow安装说明(截至2017年8月20日)需要安装cuDNN v5.1,但我的Tensorflow安装(按照virtualenv中的安装说明)需要cuDNN v6.x(如错误所示).我不知道这是我的错误还是Tensorflow文档.不过,上述解决方案对我有用.

Answer 5

上述错误通常是由于运行脚本时未指定 Cuda SDK 或 cuDNN 的版本号而导致的configure。换句话说，在运行configure脚本时，始终指定版本号以响应以下两个问题：

• Please specify the Cuda SDK version you want to use, e.g. 7.0.
• Please specify the cuDNN version you want to use.

不接受系统默认值。
