Setting up a full Torch&#x2F;Caffe&#x2F;Theano stack is not easy because there are so many libraries and moving pieces which must interact with Nvidia&#x27;s proprietary blobs and libraries and ever-changing GPUs, that you can follow all the directions and either work or fail with an utterly inscrutable error. (For example, I&#x27;m running on an old Ubuntu because the newer Ubuntu is not officially supported, and my usual OS, Debian, just does not work no matter what I try.)
