# We use a lazy-loading trick to load the backend code as needed; this avoids
# the need for a hard dependency on both backends.
# This is effectively equivalent to:
# include("tensorflow/tensorflow.jl")
# using .TF
# export tf
# but instead of loading immediately, we wait until `tf` is first called.
