title: libcublas.so.9.0: cannot open shared object file: No such file or directory in Ubuntu 18.04
body: <p>I am trying to install tensorflow in <code>Ubuntu 18.04</code>. CUDA and cudnn tests all pass. The title of this question is my error when testing the tensorflow installation. I saw the same question asked for <code>Ubuntu 16.04</code>, but the answers were not immediately helpful. One answer suggested the use of strace, but I do not understand the output.   </p>
  
  <p>Here is my full error message:</p>
