Node

Constructor

Node(graph, node_id, name=None, module=None, module_builder=None, datasource=None, datasource_builder=None, module_wiring=None)

Parameters

Name	Description
graph Required	Graph The graph this node belongs to.
node_id Required	str The ID of the node.
name	str The name of the graph. default value: None
module	Module The module associated with the Node. default value: None
module_builder	<xref:azureml.pipeline.core._ModuleBuilder> The module builder associated with the Node. default value: None
datasource	DataSource The datasource associated with the Node. default value: None
datasource_builder	<xref:azureml.pipeline.core._DatasourceBuilder> The datasource builder associated with the Node. default value: None
module_wiring	Dict[str, object] A mapping between the node's inputs/outputs and the module inputs/outputs. Holds two keys, inputs and outputs, each mapped to a dict whose keys are the module's inputs/outputs names, and the values are the node's ports. default value: None
graph Required	Graph The graph this node belongs to.
node_id Required	str The ID of the node.
name Required	str The name of the node.
module Required	Module The module associated with the Node.
module_builder Required	<xref:azureml.pipeline.core._ModuleBuilder> The module builder associated with the Node.
datasource Required	DataSource The datasource associated with the Node.
datasource_builder Required	<xref:azureml.pipeline.core._DatasourceBuilder> The datasource builder associated with the Node.
module_wiring Required	Dict[str, object] A mapping between the node's inputs/outputs and the module inputs/outputs. Holds two keys, inputs and outputs, each mapped to a dict whose keys are the module's inputs/outputs names, and the values are the node's ports.

Methods

get_input	Return an InputPort by name.
get_output	Return an OutputPort by name.
get_param	Return a parameter by name.
run_after	Run this node after the given node. If you want to run a step, for example, step3 after both step1 and step2 are completed, you can use: step3.run_after(step1) step3.run_after(step2)
sequence	Configure a list of nodes to run in sequence after this node.

get_input

Return an InputPort by name.

get_input(name)

Parameters

Name	Description
name Required	str Name of the input port.

Returns

Type	Description
InputPort	The input port with the matching name.

get_output

Return an OutputPort by name.

get_output(name)

Parameters
