Creating a Workflow

To create a workflow, define each phase by referring to Creating Workflow Phases. Follow these steps:

  1. Sort out scenarios, understand preset steps' functions, and determine the DAG structure.
  2. Debug single-phase functions like training or inference on ModelArts.
  3. Choose the code template that matches the phase function and fill in the details.
  4. Arrange phases according to the DAG structure to create a workflow.

Importing the Workflow Data Package

When creating a workflow, required objects are imported through workflow packages. The details are as follows:

from modelarts import workflow as wf
