title: Is there a way to install python 3 and python 2 in the same conda environment?
body: <p>I am trying to create a pipeline but one of the packages I need uses python2 only.  I want everything installed in the same environment so when I send out the pipeline to people I can give them a single <code>conda create --name pipeline_env blah blah blah</code>. </p>
  
  <p>Is it possible to do this but have <code>python3</code> as the default python version but have <code>python2</code> as an executable in <code>bin</code>? </p>
