    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

size(
    name=None
)

Compute the number of elements in this table.

Args
name	A name for the operation (optional).
