morpheus.stages.postprocess.add_scores_stage.AddScoresStage
- class AddScoresStage(c, *, labels=None, prefix='', probs_type=<TypeId.FLOAT32: 9>)[source]
Bases:
morpheus.stages.postprocess.add_scores_stage_base.AddScoresStageBase
Add probability scores to each message.
Add score labels based on probabilities calculated in inference stage. Label indexes will be looked up in the Config.class_labels property.
- Parameters
- c
morpheus.config.Config
- labelstyping.List[str], default = None, multiple = True, show_default = “[Config.class_labels]”
- prefixstr, default = “”
- probs_type
morpheus.common.TypeId
, default = “float32”
Pipeline configuration instance.
Converts probability indexes into classification labels. Each item in the list will determine its index from the Config.class_labels property and must be one of the available class labels. Leave as None to add all labels in the Config.class_labels property.
Prefix to add to each label. Allows adding labels different from the
Config.class_labels
property.Datatype of the scores columns.

Stages which need to have columns inserted into the dataframe, should populate the
self._needed_columns
dictionary with mapping of column names tomorpheus.common.TypeId
.join
()Awaitable method that stages can implement this to perform cleanup steps when pipeline is stopped.
on_start
()This function can be overridden to add usecase-specific implementation at the start of any stage in the pipeline.
This function is called along with on_start during stage initialization.
stop
()Stages can implement this to perform cleanup steps when pipeline is stopped.
Specifies whether this Stage is capable of creating C++ nodes.
- _build(builder, in_ports_streams)[source]
This function is responsible for constructing this stage’s internal
mrc.SegmentObject
object. The input of this function contains the returned value from the upstream stage.The input values are the
mrc.Builder
for this stage and aStreamPair
tuple which contain the inputmrc.SegmentObject
object and the message data type.- Parameters
- builder
mrc.Builder
- in_ports_streams
morpheus.pipeline.pipeline.StreamPair
mrc.Builder
object for the pipeline. This should be used to construct/attach the internalmrc.SegmentObject
.List of tuples containing the input
mrc.SegmentObject
object and the message data type.- builder
- Returns
typing.List[morpheus.pipeline.pipeline.StreamPair]
List of tuples containing the output
mrc.SegmentObject
object from this stage and the message data type.
- accepted_types()[source]
Accepted input types for this stage are returned.
- Returns
- typing.Tuple[
morpheus.pipeline.messages.MultiResponseMessage
, ]
Accepted input types.
- typing.Tuple[
- build(builder, do_propagate=True)[source]
Build this stage.
- Parameters
- builder
mrc.Builder
- do_propagatebool, optional
MRC segment for this stage.
Whether to propagate to build output stages, by default True.
- builder
- can_build(check_ports=False)[source]
Determines if all inputs have been built allowing this node to be built.
- Parameters
- check_portsbool, optional
Check if we can build based on the input ports, by default False.
- Returns
- bool
True if we can build, False otherwise.
- get_all_input_stages()[source]
Get all input stages to this stage.
- Returns
- typing.List[
morpheus.pipeline.pipeline.StreamWrapper
]
All input stages.
- typing.List[
- get_all_inputs()[source]
Get all input senders to this stage.
- Returns
- typing.List[
morpheus.pipeline.pipeline.Sender
]
All input senders.
- typing.List[
- get_all_output_stages()[source]
Get all output stages from this stage.
- Returns
- typing.List[
morpheus.pipeline.pipeline.StreamWrapper
]
All output stages.
- typing.List[
- get_all_outputs()[source]
Get all output receivers from this stage.
- Returns
- typing.List[
morpheus.pipeline.pipeline.Receiver
]
All output receivers.
- typing.List[
- get_needed_columns()[source]
Stages which need to have columns inserted into the dataframe, should populate the
self._needed_columns
dictionary with mapping of column names tomorpheus.common.TypeId
. This will ensure that the columns are allocated and populated with null values.- property has_multi_input_ports: bool
Indicates if this stage has multiple input ports.
- Returns
- bool
True if stage has multiple input ports, False otherwise.
- property has_multi_output_ports: bool
Indicates if this stage has multiple output ports.
- Returns
- bool
True if stage has multiple output ports, False otherwise.
- property input_ports: List[morpheus.pipeline.receiver.Receiver]
Input ports to this stage.
- Returns
- typing.List[
morpheus.pipeline.pipeline.Receiver
]
Input ports to this stage.
- typing.List[
- property is_built: bool
Indicates if this stage has been built.
- Returns
- bool
True if stage is built, False otherwise.
- async join()[source]
Awaitable method that stages can implement this to perform cleanup steps when pipeline is stopped. Typically this is called after
stop
during a graceful shutdown, but may not be called if the pipeline is terminated.- property name: str
The name of the stage. Used in logging. Each derived class should override this property with a unique name.
- Returns
- str
Name of a stage.
- on_start()[source]
This function can be overridden to add usecase-specific implementation at the start of any stage in the pipeline.
- property output_ports: List[morpheus.pipeline.sender.Sender]

- Returns
- typing.List[
morpheus.pipeline.pipeline.Sender
]
Output ports from this stage.
- typing.List[
- async start_async()[source]
This function is called along with on_start during stage initialization. Allows stages to utilize the asyncio loop if needed.
- stop()[source]
Stages can implement this to perform cleanup steps when pipeline is stopped.
- supports_cpp_node()[source]
Specifies whether this Stage is capable of creating C++ nodes. During the build phase, this value will be combined with
CppConfig.get_should_use_cpp()
to determine whether or not a C++ node is created. This is an instance method to allow runtime decisions and derived classes to override base implementations.- property unique_name: str
Unique name of stage. Generated by appending stage id to stage name.
- Returns
- str
Unique name of stage.
