Get Caffe

A Caffe installation is required if the SNPE SDK is going to be used with Caffe.

To clone and build Caffe from open source (https://github.com/BVLC/caffe) use git commit SHA 18b09e807a6e146750d84e89a961ba8e678830b4 as this SHA has been tested with the SNPE SDK. Other SHAs may also work but have not been tested.
```
cd <path_to_caffe>
git reset --hard 18b09e807a6e146750d84e89a961ba8e678830b4
```
Instructions to build Caffe on ubuntu 16.04 are available here: http://caffe.berkeleyvision.org/install_apt.html

A list of commands needed as part of compiling and installing Caffe are available here: http://caffe.berkeleyvision.org/installation.html#compilation. A summary of the necessary steps is provided below.

cp Makefile.config.example Makefile.config
make all
make test
make runtest
make distribute
make pycaffe <---- This is an important step because
                   snpe-caffe-to-dlc conversion script
                   relies on Caffe python bindings

Now continue with the rest of the SNPE Setup

Get Caffe2

Caffe2 is a rapidly evolving project. You may install Caffe2 from prebuilt binaries for Ubuntu or build from sources.

This link (Caffe2) provides the most up to date instructions for setting up Caffe2.
