# API Reference ## KerasModelImport [\[source\]](https://github.com/eclipse/deeplearning4j/tree/master/deeplearning4j/deeplearning4j-modelimport/src/main/java/org/deeplearning4j/nn/modelimport/keras/KerasModelImport.java) 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. **importKerasModelAndWeights** ``` public static ComputationGraph importKerasModelAndWeights( InputStream modelHdf5Stream, boolean enforceTrainingConfig)
