TensorFlow: libcudart.so.7.5: cannot open shared object file: No such file or directory
<p>I am running TensorFlow on Ubuntu 15.10. When I enter <code>pip show tensorflow</code>, I see that TF has been installed properly.</p>

<p>However, when I write <code>import tensorflow as tf</code>, I get the following error message:</p>

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

<p>For what it's worth, I have followed the instructions <a href="https://www.tensorflow.org/versions/r0.7/get_started/os_setup.html#optional-linux-enable-gpu-support" rel="noreferrer">here</a> and set my <code>LD_LIBRARY_PATH</code> and <code>CUDA_HOME</code> environment variables.</p>

<p>Any advice?</p>

<p><strong>EDIT:</strong></p>

<p>I have installed CUDA 7.5 and added these to my <code>.profile</code> file:</p>

<pre><code>export LD_LIBRARY_PATH="/usr/local/cuda-7.5/lib64"
export CUDA_HOME=/usr/local/cuda-7.5
</code></pre>

<p>However, I continue to see the same error message.</p>

<p><strong>EDIT:</strong></p>

<p>I see the following output when I run <code>ldd /usr/local/cuda-7.5/lib64/libcudart.so.7.5</code>:</p>

<pre><code>linux-vdso.so.1 =&gt;  (0x00007ffdac7ea000)

</code></pre>

<p><strong>EDIT:</strong></p>

<p>If it is relevant, I use GeForce GT640.</p>

<p><strong>EDIT:</strong></p>

<p>I followed <a href="https://stackoverflow.com/a/36161286/3559686">@tommus' advice</a> and called <code>source ~/.profile</code> before running TensorFlow, and now it works like a charm.</p>

<p>Thanks to everyone who tried to help me in the comments -- this is my first experience with any kind of Linux distribution, and I am really <strong>very appreciative</strong> of all the patient assistance I have received so far :-) You guys are absolutely awesome!</p>
