	### An example of building a TensorFlow model from R using rPython ###
	# For this script you need to
	# 1. Have python 2.7 installed.
	# 2. Install the rPython package in R.
	# 3. Install Google's TensorFlow library as per these instructions:
	# http://www.tensorflow.org/get_started/os_setup.md#binary_installation

	### Here is how to setup and run a trivial TensorFlow model ###

	# Load TensorFlow (I couldn't get this to work without setting sys.argv... )

	# See ?reactive for meanings of x, env, quoted, and domain.
	# paused indicates the starting state of the pauseable reactive.
	pauseableReactive <- function(x, env = parent.frame(), quoted = FALSE,
	priority = 0, domain = shiny::getDefaultReactiveDomain(), paused = FALSE) {
	shiny::installExprFunction(x, "func", eval.env = env, quoted = quoted)

	vals <- shiny::reactiveValues(value = NULL)
	obs <- shiny::observe(vals$value <- func(), priority = priority,
	domain = domain, suspended = paused)
	return(structure(
