Args |
data_format
|
(string) See RankingDataFormat.
|
context_feature_spec
|
(dict) Map from feature keys to FixedLenFeature or
VarLenFeature values.
|
example_feature_spec
|
(dict) Map from feature keys to FixedLenFeature or
VarLenFeature values.
|
list_size
|
(int) The number of examples to keep. If specified, truncation or
padding may happen. Otherwise, set it to None to allow dynamic list size
(recommended).
|
size_feature_name
|
(str) Name of feature for example list sizes. Populates
the feature dictionary with a tf.int32 Tensor of shape [batch_size] for
this feature name. If None, which is default, this feature is not
generated.
|
mask_feature_name
|
(str) Name of feature for example list masks. Populates
the feature dictionary with a tf.bool Tensor of shape [batch_size,
list_size] for this feature name. If None, which is default, this feature
is not generated.
|
receiver_name
|
(string) The name for the receiver tensor.
|
default_batch_size
|
(int) Number of instances expected per batch. Leave
unset for variable batch size (recommended).
|
Returns |
A tf.estimator.export.ServingInputReceiver object, which packages the
placeholders and the resulting feature Tensors together.
