tf.contrib.layers.sequence_input_from_feature_columns

Builds inputs for sequence models from FeatureColumns. (experimental)

tf.contrib.layers.sequence_input_from_feature_columns(
    columns_to_tensors, feature_columns, weight_collections=None, trainable=True,
    scope=None
)

See documentation for input_from_feature_columns. The following types of FeatureColumn are permitted in feature_columns: _OneHotColumn, _EmbeddingColumn, _ScatteredEmbeddingColumn, _RealValuedColumn, _DataFrameColumn. In addition, columns in feature_columns may not be constructed using any of the following: ScatteredEmbeddingColumn, BucketizedColumn, CrossedColumn.

Args
columns_to_tensors	A mapping from feature column to tensors. 'string' key means a base feature (not-transformed). It can have FeatureColumn as a key too. That means that FeatureColumn is already transformed by input pipeline.
feature_columns	A set containing all the feature columns. All items in the set should be instances of classes derived by FeatureColumn.
weight_collections	List of graph collections to which weights are added.
trainable	If True also add variables to the graph collection GraphKeys.TRAINABLE_VARIABLES (see tf.Variable).
scope	Optional scope for variable_scope.

Returns
A Tensor which can be consumed by hidden layers in the neural network.

Raises
ValueError	if FeatureColumn cannot be consumed by a neural network.
