python - TensorFlow:libcudart.so.7.5:无法打开共享对象文件:没有这样的文件或目录

Question

我在 Ubuntu 15.10 上运行 TensorFlow。当我输入pip show tensorflow时，我看到TF已经正确安装了。

但是，当我编写 import tensorflow as tf 时，我收到以下错误消息:

Traceback (most recent call last):

ImportError: libcudart.so.7.5: cannot open shared object file: No such file or directory

对于它的值(value)，我已按照说明 here并设置我的 LD_LIBRARY_PATH 和 CUDA_HOME 环境变量。

有什么建议吗？

编辑:

我已经安装了 CUDA 7.5 并将这些添加到我的 .profile 文件中:

export LD_LIBRARY_PATH="/usr/local/cuda-7.5/lib64"
export CUDA_HOME=/usr/local/cuda-7.5

但是，我仍然看到相同的错误消息。

编辑:

我在运行 ldd/usr/local/cuda-7.5/lib64/libcudart.so.7.5 时看到以下输出:

linux-vdso.so.1 =>  (0x00007ffdac7ea000)
libc.so.6 => /lib/x86_64-linux-gnu/libc.so.6 (0x00007fc27a281000)

如果相关，我使用 GeForce GT640。

编辑:

我关注了@tommus' advice并在运行 TensorFlow 之前调用了 source ~/.profile，现在它就像一个魅力。

感谢所有试图在评论中帮助我的人——这是我第一次使用任何类型的 Linux 发行版，我真的非常感谢我收到的所有耐心帮助远 :-) 你们真是太棒了!

编辑 .profile 文件后，您要么需要注销并重新登录，要么运行以下命令:

来源 ~/.profile

解决方案是持久的，因此无需再次执行。
