How to train new TensorFlow Lite micro speech models

We recommend training with Colab since you won't have to deal with Docker management. That said, it is possible to docker-ize training

We need to be able to run a specific version/commit of TensorFlow and the dependancy requirements for TF are very extreme. We strongly suggest against trying to compile and run on your native computer OS - that way we don't get weird interactions with your OS, compiler toolchain, Python kit, etc. Also, TF really wants to run on a particular version of Linux and chances are you aren't running it.

Instead, we will be using Docker to containerize and separate the TF build so we have a compact, clean, dependable build. Docker is lighter than VMWare/vagrant, and has a very nice 'hub' backend for saving/restoring your images, all for free!

	Signup and log into Docker Sign up at https://hub.docker.com/signup You don't need to pay for an account, but be aware the software images we'll be using are public so don't put any private data in em!
	Download and Install Desktop Docker Download Docker software for Windows or Mac, whichever matches your computer
	TensorFlow needs a lot of computing resources Give it as many CPUs and as much RAM as you can spare You need to give it at least 8 GB of RAM or gcc will fail with a very annoying and somewhat confusing error like this (but on some other file)
