Our goal is to run python -c "import caffe"
without crashing. For anyone who doesn't spend most of their time with build systems, getting to this point can be extremely difficult on OS X. Instead of providing a list of steps to follow, I'll try to explain why each step happens.
This page has OS X specific install instructions.
