Virtualenv 20.0.0 Released (opens in new tab)

Yeah, I guess it's called different, but has the same functionality and is a drop-in replacement. I'm surprised there's still development on virtualenv after 2.7 is EOL.

This is an HPC environment, so besides a nice, working version of TensorFlow, there are large numbers of pre-built scientific/bioinformatics packages. This is a huge win when you're running with a skeleton crew.

Also, note this is for system-wide, not per-user usage. I'm kind of vague on how virtualenv would handle this, plus it feels like it's changed a lot over time. (?)

They provide useful packages that aren't (easily) available via pip. For example, numpy with MKL or Tensorflow GPU builds that don't require/presuppose CPU support for new vector instructions. Moreover, their package installs don't break as randomly as some pip packages, presumably because someone bothered to do more testing of commonly used packages included in the default package repository.
