Keras Import API Overview

Keras model import API

KerasModelImport

[source]

Reads stored Keras configurations and weights from one of two archives: either as

  • a single HDF5 file storing model and training JSON configurations and weights

  • separate text file storing model JSON configuration and HDF5 file storing weights.
