Evren

NOTE: Project is in experimental phase.

Evren is pre-optimizer and exporter for machine learning models to embedded systems, android and iOS platforms. Currently Android and iOS supported, for iOS it can export caffe and keras models, for Android it exports keras models. Keras models should use Tensorflow backend.

Installation

After cloning use tox to setup environment.

$ tox

Usage

You can find examples in examples directory. Documentation will be made available soon.

Minimal export code can be:

MODEL_NAME = "dense_android_test"

# Define Keras model
model = Sequential()
model.add(Dense(10, input_shape=(10, 1)))
model.add(Dense(10))
model.add(Dense(10))
model.add(Dense(10))
model.add(Dense(10))
model.add(Dense(10))
model.add(Dense(1, activation='sigmoid'))

# Train it in here, just because it is demonstration we ignore that
# . . . . . . TRAINING . . . . . .

# If you know the output nodes you
# don't need to call underlying output nodes list

output_nodes = get_output_node_names()

# Write Keras model with weights as protobuf file
# for use with Tensorflow Lite and Android NDK
# It will produce `dense_android_test.pb` with weights embedded in.
export_keras_to_file(model_name=MODEL_NAME,
                     input_names=map(str, range(1, 10)),
                     output_names=output_nodes,
                     out_file_name=MODEL_NAME)

TODO

• Caffee export for Android
• Extra optimization techniques for Android and iOS.
• Travis setup with Tox.
