Inherits From: LookupInterface
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 |

Methods
lookup
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
size(
name=None
)
Compute the number of elements in this table.
| Args | |
|---|---|
name |
