tfmicro
======

## Developing

Update submodules:

```
git submodule init
git submodule update
```

Then we need to tell tensorflow to download its own dependencies. Actually
building one of the tensorflow micro examples does this, and as a side
effect checks that tensorflow is working.

```
cd submodules/tensorflow
make -f tensorflow/lite/micro/tools/make/Makefile test_micro_speech_test
cd ../..
```

Then we can build!

```
cargo test
```

We use the `env_logger` crate for log output in tests, try

```
RUST_LOG=info cargo test
```

Changes in the tensorflow source tree aren't tracked by cargo. If the
tensorflow source has changed, use the `build` feature gate to force a
re-build.

```
cargo build --features build
```

To debug `build.rs` itself, try `cargo build -vv`

## Updating tensorflow

Some tips for trying out new tensorflow verions

#### Use the build script to automatically run git biscect

```
cd submodules/tensorflow
```

Mark the current revision as good

```
git bisect start
git bisect good
```

Grab the latest head

```
git fetch origin
git checkout origin/master
git bisect bad     # Presumably it's bad
```

Run the build script

```
git bisect run ../../build.sh
```

Go do something else for a few hours, then git will tell you which commit was
bad.

## Releasing

* Update version in Cargo.toml and lib.rs
* Create with `cargo readme > README.md`
