MXNet Clojure Environment

1.
Setup

Clojure deps.edn file, which will be mounted into the filesystem when the runtime boots—this installs MXNet and the Clojure frontend. Note that the current version of Clojure/MXNet is compiled against CUDA 9.0, so we must set NEXTJOURNAL_MOUNT_CUDA appropriately in the runtime config.

{ :deps {
  org.apache.mxnet.contrib.clojure/clojure-mxnet-linux-gpu {
    :mvn/version "1.3.1" },
  nu.pattern/opencv {:mvn/version "2.4.9-7"},
  net.mikera/imagez {:mvn/version "0.12.0"},
  thinktopic/think.image {:mvn/version "0.4.16"}}}
