GPU tensorflow install issue

Question

I am a new user to Ubuntu, and I spent more than a week trying to install gpu tensorflow. I tried to follow the tutorials from the website and blogs. But whenever I import tensorflow in my python console. It always shows:

import tensorflow
I tensorflow/stream_executor/dso_loader.cc:128] successfully opened CUDA library libcublas.so.8.0 locally

I tensorflow/stream_executor/dso_loader.cc:128] successfully opened CUDA library libcurand.so.8.0 locally

I tried to search the answer all over google, but no real solution came up yet.Can anyone help me out?

Answer 1

Based on the output for $ ls /usr/local/cuda , you have installed it successfully.

Now, what is missing there is the PATH definition so that TensorFlow can find where it is.

1) Open your .bashrc file: gedit ~/.bashrc

2) Append the following two lines to the end of the file:

export LD_LIBRARY_PATH="$LD_LIBRARY_PATH:/usr/local/cuda/lib64:/usr/local/cuda/extras/CUPTI/lib64:/usr/local/cuda/include"  
export CUDA_HOME=/usr/local/cuda

3) Once you save and close the text file you can return to your original terminal and type this command to reload your .bashrc file:

source ~/.bashrc

Although the third part is supposed to take care of that, if you want to be 100% sure that it will work restart the computer.

Now, for TensorFlow, remember to set the CUDA path as /usr/local/cuda and the version to 8.0.
