I'm following along with the pyimagesearch book, which comes with an ubuntu 16.04 virtual machine that already has all the libraries (sklearn, keras, etc.) installed and everything setup. When I first ran some of the code with keras, however, I got the warning The TensorFlow library wasn't compiled to use SSE4.2 instructions, but these are available on your machine and could speed up CPU computation, and the same for AVX. I looked at this question as well as installing from source, but both seem to assume that TensorFlow hasn't been installed yet, which it already has. Do I just have to uninstall and start over? Or is there something else I can do?

It's just a warning, it won't stop you from using TensorFlow. But if you would like TensorFlow to use these instructions, you'll need to re-install it. TensorFlow 1.6+ pip packages are compiled with AVX by default, but for other instructions you'd need to compile TensorFlow from source.
