title: How do I install python packages inside of a singularity container?
body: <p>I am trying to install packages with pip on my singularity container, but there seems to be no way of doing so without &quot;borrowing&quot; the packages from my machine. I have heard that I may need to use virtualenv's but even that seems to be a circuitous process. Does anyone know of a tried and true way of using packages from pip on their singularity container?</p>
