Returns a feature column that represents sequences of numeric data.


temperature = sequence_numeric_column('temperature')
columns = [temperature]

features =, features=make_parse_example_spec(columns))
input_layer, sequence_length = sequence_input_layer(features, columns)

rnn_cell = tf.compat.v1.nn.rnn_cell.BasicRNNCell(hidden_size)
outputs, state = tf.compat.v1.nn.dynamic_rnn(
    rnn_cell, inputs=input_layer, sequence_length=sequence_length)

key A unique string identifying the input features.
shape The shape of the input data per sequence id. E.g. if shape=(2,), each example must contain 2 * sequence_length values.
default_value A single value compatible with dtype that is used for padding the sparse data into a dense Tensor.
dtype The type of values.
normalizer_fn If not None, a function that can be used to normalize the value of the tensor after default_value is applied for parsing. Normalizer function takes the input Tensor as its argument, and returns the output Tensor. (e.g. lambda x: (x - 3.0) / 4.2). Please note that even though the most common use case of this function is normalization, it can be used for any kind of Tensorflow transformations.

A _SequenceNumericColumn.

TypeError if any dimension in shape is not an int.
ValueError if any dimension in shape is not a positive integer.
ValueError if dtype is not convertible to tf.float32.
