alt-model-checkpoint 1.13.0

An adapter callback for Keras ModelCheckpoint that allows checkpointing an alternate model (often submodel of a multi-GPU model).

An adapter callback for Keras ModelCheckpoint that allows checkpointing an alternate model (often submodel of a multi-GPU model).

Installation

pip install alt-model-checkpoint

Usage

You must provide your own Keras or Tensorflow installation. See Pipfile for preferred versions.

If using the Keras bundled in Tensorflow:

from alt_model_checkpoint.tensorflow import AltModelCheckpoint

If using Keras standalone:

from alt_model_checkpoint.keras import AltModelCheckpoint

Common usage involving multi-GPU models built with Keras multi_gpu_model():

from alt_model_checkpoint.keras import AltModelCheckpoint
from keras.models import Model
from keras.utils import multi_gpu_model

base_model = Model(...)
gpu_model = multi_gpu_model(base_model)
gpu_model.compile(...)

gpu_model.fit(..., callbacks=[
    AltModelCheckpoint('save/path/for/model.hdf5', base_model)
])

Dev environment setup

1. Install pipenv.
2. Run make test (runs make test-build automatically to ensure deps)
