Sagemaker pipeline condition step and workflow path

Question

![Enter image description here](/media/postImages/original/IMSrxNbBhIS5SX8DXoQA1WMQ)
I'm trying to implement a pipeline as shown in the image. If '**AblaoneMSECond**' is true then '**face_processing**'  and '**sentiment_processing**'  should be executed else '**face_attr_processing**'  and  '**sentiment_processing**' should be executed.

But when the cond is true the workflow stops with '**face_processing**' and the '**sentiment_processing**' step is not executed as its waiting for '**face_attr_processing**' step.

Is there a way to continue with '**sentiment_processing**' even if '**face_attr_processing**'  is not executed ?

Answer

Hello,

Thank you for using AWS SageMaker service. Condition step is used to evaluate the condition of step properties to assess which action should be taken next in the pipeline.

A condition step requires a list of conditions, a list of steps to run if the condition evaluates to true, and a list of steps to run if the condition evaluates to false.

Condition step has the following limitations :

* SageMaker Pipelines doesn't support the use of nested condition steps. You can't pass a condition step as the input for another condition step.
* A condition step can't use identical steps in both branches. If you need the same step functionality in both branches, duplicate the step and give it a different name. [1]

Kindly attempt creating a duplicate step with a different name in last step and if the issue still persists, please reach out to AWS Support[2] (Sagemaker), along with your issue/use case in detail and share relevant AWS resource names. We will troubleshoot accordingly.
