Creates an empty hash table that uses tensors as the backing store.
tf.raw_ops.MutableDenseHashTable(
empty_key,
value_dtype,
container='',
shared_name='',
use_node_name_sharing=False,
value_shape=[],
initial_num_buckets=131072,
max_load_factor=0.8,
name=None
)
It uses "open addressing" with quadratic reprobing to resolve
collisions.
This op creates a mutable hash table, specifying the type of its keys and
values. Each value must be a scalar. Data can be inserted into the table using
the insert operations. It does not support the initialization operation.
Args |
|---|
empty_key
|
A Tensor.
The key used to represent empty key buckets internally. Must not
be used in insert or lookup operations.
|
value_dtype
|
A tf.DType. Type of the table values.
|
container
|
An optional string. Defaults to "".
If non-empty, this table is placed in the given container.
Otherwise, a default container is used.
|
shared_name
|
An optional string. Defaults to "".
If non-empty, this table is shared under the given name across
multiple sessions.
|
use_node_name_sharing
|
An optional bool. Defaults to False.
|
value_shape
|
An optional tf.TensorShape or list of ints. Defaults to [].
The shape of each value.
|
initial_num_buckets
|
An optional int. Defaults to 131072.
The initial number of hash table buckets. Must be a power
to 2.
|
max_load_factor
|
An optional float. Defaults to 0.8.
The maximum ratio between number of entries and number of
buckets before growing the table. Must be between 0 and 1.
|
name
|
A name for the operation (optional).
|
Returns |
|---|
A Tensor of type mutable string.
