Class ComponentSpec

A specification of the inputs, outputs and parameters for a component.

Aliases: tfx.types.component_spec.ComponentSpec

Components should have a corresponding ComponentSpec inheriting from this class and must override:

• PARAMETERS (as a dict of string keys and ExecutionParameter values),
• INPUTS (as a dict of string keys and ChannelParameter values) and
• OUTPUTS (also a dict of string keys and ChannelParameter values).

Here is an example of how a ComponentSpec may be defined:

class MyCustomComponentSpec(ComponentSpec): PARAMETERS = { 'internal_option': ExecutionParameter(type=str), } INPUTS = { 'input_examples': ChannelParameter(type=standard_artifacts.Examples), } OUTPUTS = { 'output_examples': ChannelParameter(type=standard_artifacts.Examples), }

To create an instance of a subclass, call it directly with any execution parameters / inputs / outputs as kwargs. For example:

spec = MyCustomComponentSpec( internal_option='abc', input_examples=input_examples_channel, output_examples=output_examples_channel)

Attributes:

• PARAMETERS: a dict of string keys and ExecutionParameter values.
• INPUTS: a dict of string keys and ChannelParameter values.
• OUTPUTS: a dict of string keys and ChannelParameter values.
