Tricks for working with many virtualenv environments on a Linux server.

Much of this was adapted from Justin Abrahms. I've just collected the bits related to setting up the environment in bash here.

Assumptions

This page assumes that you have access to pip, but that you are not the administrator (no root or sudo access).

Get virtualenv if it isn't installed

If you don't have virtualenv installed, you can do:

pip install --user virtualenv

jcausey-astate

#!/bin/bash
script="$(basename ${0})"
read -r -d '' USAGE <<-EOF

Watches a specified process (by pid or name) and runs
a specified command after it exits.
If watching by name, the command executes when no process 
by that name is running.

Usage:

jcausey-astate

/**
* EXAMPLE FROM: https://iamtrask.github.io/2015/07/12/basic-python-network/
*  I'm replicating the "3 Layer Neural Network" code using C++ and Eigen below.
*  This network is trying to learn to recognize an XOR in the first two elements
*  of a 3-value vector, the third value doesn't matter.
