<div dir="ltr"><p dir="ltr">If you are on Windows machine and will be using numpy/scipy, definitely use conda over virtualenv/pyvenv.

</p>So if you're using Linux machine and not using packages that depend on C or Fortran compilation, maybe there isn't too much advantage to using conda over virtualenv/pyvenv. But conda has some nifty commands that make it easy to create a python 2 vs python 3 environment. For example, if you install conda installation for python 3, you can still create a python 2 environment by just adding python=2 or python=2.7 in the conda command (<a href="http://continuum.io/blog/anaconda-python-3">http://continuum.io/blog/anaconda-python-3</a>). I can see if you just want to stick with the tooling that comes with your default Python installation that you would just stick with pyvenv instead of having to install a 3rd party package management system like Anaconda/conda. But for me, I just got tired of the hassle with compiling.<br><p>For a list of packages that are available by default by conda: <a href="http://docs.continuum.io/anaconda/pkg-docs.html">http://docs.continuum.io/anaconda/pkg-docs.html</a><br></p><p dir="ltr">CAVEAT: I've only been using Python for maybe 4 or 5 yrs and Linux even less, so I could be wrong with the details.

What do you think of conda versus virtualenv?<br>
Would you drop (or have you dropped) virtualenv to use conda instead?<br>
