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

Question

我想在我的系统上使用tensorflow-gpu.我重新安装了很多次,它给出了下面的错误.但是当我使用tensorflow-cpu时它工作正常.我安装了cuda 8.0工具包和cudnn 5.1.

  Traceback (most recent call last):
  File "finetune.py", line 17, in <module>
    import tensorflow as tf

Answer 1

如果更改路径变量不起作用,在终端中运行以下内容通常可以解决这个问题:

sudo ldconfig /usr/local/cuda/lib64

(有时cuda可能需要类似的东西cuda-8.0,具体取决于您的安装)

Answer 2

问题是您没有CUDA_HOME设置环境变量。如果你认为你已经安装了 CUDA，那么你需要确保上面的环境变量设置为 prob=perly 并且包含所有共享库所在的 CUDA 安装目录的地址。

export CUDA_HOME=/CUDA/installation/path
export LD_LIBRARY_PATH="$LD_LIBRARY_PATH:$CUDA_HOME/lib64:$CUDA_HOME/extras/CUPTI/lib64"
