title: Nvcc missing when installing cudatoolkit?
body: <p>I have installed cuda along pytorch with</p>
  
  <pre><code>conda install pytorch torchvision cudatoolkit=10.0 -c pytorch
  </code></pre>
  
  <p>However, it seems like nvcc was not installed along with it. If I want to use for example <code>nvcc -V</code>, I get the error that nvcc was not found, and that I should install it with <code>sudo apt install nvidia-cuda-toolkit.</code> 
  Can I do this (I dont want to just try and then find out that it is not working/messes up the whole cuda setup).
  And is this a bug or expected behavior?</p>
  
  <p>I am using Ubuntu 18.04 and have cuda 10.2</p>
