tf.contrib.lookup.InitializableLookupTableBase

Initializable lookup table interface.

tf.contrib.lookup.InitializableLookupTableBase(
    default_value, initializer
)

An initializable lookup tables persist across different steps.

Args
`default_value`	The value to use if a key is missing in the table.
`initializer`	The table initializer to use.

Attributes
`default_value`	The default value of the table.
`key_dtype`	The table key dtype.
`name`	The name of the table.
`resource_handle`	Returns the resource handle associated with this Resource.
`value_dtype`	The table value dtype.

Methods

lookup(
    keys, name=None
)

Looks up keys in a table, outputs the corresponding values.

The default_value is used for keys not present in the table.

Args
`keys`	Keys to look up. May be either a `SparseTensor` or dense `Tensor`.
`name`	A name for the operation (optional).

Returns
A `SparseTensor` if keys are sparse, otherwise a dense `Tensor`.

Raises
`TypeError`	when `keys` or `default_value` doesn't match the table data types.

size(
    name=None
)

Compute the number of elements in this table.

Args
`name`	A name for the operation (optional).

Returns
A scalar tensor containing the number of elements in this table.
