title: Is that a bad idea to use conda and pip install on the same environment?
body: <p>Since <code>conda install</code> and <code>pip install</code> in many cases do essentially the same thing, what would be the best option? Is there a case when someone should stick to <code>pip install</code> only? Symmetrical, is there a case when one should stick to <code>conda install</code> only? Is there a way to shoot in one's foot by using both conda and pip install in a single environment?</p>
  <p>If both approaches are essentially the same and don't contradict each other there should be no reason to stick solely to one of them but not to the other.</p>
