THEN Ensure the workflow class has steps decorated with @step. If steps are not detected, import `get_steps_from_class` and `get_steps_from_instance` from `llama_index.core.workflow.utils` instead of the old path. Also ensure `pyvis` is installed (it is a dependency used internally by the function).

from llama_index.core.workflow.utils import get_steps_from_class, get_steps_from_instance
from llama_index.core.workflow import Workflow, step

class MyWorkflow(Workflow):
    @step
    def step1(self):
        pass

w = MyWorkflow()
