Constructor Detail

KerasSequentialModel

public KerasSequentialModel(KerasModelBuilder modelBuilder)
                     throws UnsupportedKerasConfigurationException,
                            IOException,
                            InvalidKerasConfigurationException

(Recommended) Builder-pattern constructor for Sequential model.

Parameters:

modelBuilder - builder object

Throws:

IOException - I/O exception

InvalidKerasConfigurationException - Invalid Keras configuration

UnsupportedKerasConfigurationException - Unsupported Keras configuration

KerasSequentialModel

public KerasSequentialModel(String modelJson,
                            String modelYaml,
                            Hdf5Archive weightsArchive,
                            String weightsRoot,
                            String trainingJson,
                            Hdf5Archive trainingArchive,
                            boolean enforceTrainingConfig,
                            int[] inputShape)
                     throws IOException,
                            InvalidKerasConfigurationException,
                            UnsupportedKerasConfigurationException

(Not recommended) Constructor for Sequential model from model configuration (JSON or YAML), training configuration (JSON), weights, and "training mode" boolean indicator. When built in training mode, certain unsupported configurations (e.g., unknown regularizers) will throw Exceptions. When enforceTrainingConfig=false, these will generate warnings but will be otherwise ignored.

Parameters:

modelJson - model configuration JSON string

modelYaml - model configuration YAML string

trainingJson - training configuration JSON string

Throws:

IOException - I/O exception

InvalidKerasConfigurationException

UnsupportedKerasConfigurationException
