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.当我进入时pip show tensorflow,我看到TF已正确安装.

但是,当我写import tensorflow as tf,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

为了它的价值,我按照这里的说明设置了我的LD_LIBRARY_PATH和CUDA_HOME环境变量.

有什么建议？

编辑:

我已经安装了CUDA 7.5并将它们添加到我的.profile文件中:

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

但是,我继续看到相同的错误消息.

编辑:

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

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

编辑:

如果它是相关的,我使用GeForce GT640.

编辑:

我跟着@tommus的建议并source ~/.profile在运行TensorFlow之前打电话,现在它就像一个魅力.

感谢所有试图在评论中帮助我的人 - 这是我对任何Linux发行版的第一次体验,我非常感谢到目前为止我收到的所有患者帮助:-)你们真是棒极了!

Answer 1

编辑.profile文件后,您需要注销并重新登录或运行以下命令:

source ~/.profile

解决方案是持久的,因此不需要再次执行它.

Answer 2

sudo nano /etc/ld.so.conf.d/nvidia.conf

添加：

/usr/local/cuda-8.0/lib64

/usr/local/cuda-8.0/lib

跑

sudo ldconfig

如果效果很好，请告诉我。
