示例1: __init__

shape=None,
default_value=''):
"""Initializes the LookupTensor handler.
Simply calls a vocabulary (most often, a label mapping) lookup.
Args:
tensor_key: the name of the `TFExample` feature to read the tensor from.
table: A tf.lookup table.
shape_keys: Optional name or list of names of the TF-Example feature in
which the tensor shape is stored. If a list, then each corresponds to
one dimension of the shape.
shape: Optional output shape of the `Tensor`. If provided, the `Tensor` is
reshaped accordingly.
default_value: The value used when the `tensor_key` is not found in a
particular `TFExample`.
Raises:
ValueError: if both `shape_keys` and `shape` are specified.
