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

Question

I am trying to use tensorflow-gpu on my system. I have re-installed it many times, it gives the error give below. But when I use tensorflow-cpu it works fine. I have cuda 8.0 toolkit installed and cudnn 5.1.

  Traceback (most recent call last):
  File "finetune.py", line 17, in <module>
    import tensorflow as tf
  File "/home/saurabh/code/env/local/lib/python2.7/site-packages/tensorflow/__init__.py", line 24, in <module>
    from tensorflow.python import *

    raise ImportError(msg)

Answer 1

If changing your path variable does not work, running the following in your terminal is what usually solves this for me:

sudo ldconfig /usr/local/cuda/lib64

(sometimes cuda may need to be something like cuda-8.0, depending on your installation)

Answer 2

The problem is that you don't have environment variable CUDA_HOME set. If you think you have CUDA installed, then you need to make sure that the above environment variable is set prob=perly and contains address of the CUDA installation directory where all share libraries are located.

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

Answer 3

sudo ldconfig /usr/local/cuda/lib64

Works for me.
