The following code snipped can be used to run a dpf evaluation with a CPython Python result. One neededs to install ansys-dpf-core for the ansys python first and then ansys-dpf-composites with --no-dependencies. The --no-dependencies is important because to keep the numpy version that comes with the ansys python.
Just did a quick test with the snippet below. Clear generated data causes problems because the rst file is still in use by the dpf operator and cannot be moved. The results match with the composite failure tool

        failure_criteria=[

        ],
    )
    
    load_composites_plugin(dpf._global_server(), ansys_path=dpf._global_server().ansys_path)

    composite_model = CompositeModel(composite_files_on_server, server=dpf._global_server())

    output_all_elements = composite_model.evaluate_failure_criteria(
        combined_criterion=combined_fc,
    )
    irf_field = output_all_elements.get_field({"failure_label": FailureOutput.FAILURE_VALUE})
    
    forward = dpf.Operator("forward")
    forward.connect(0, irf_field)
    forward_type = dpf.Operator("forward")
    forward_type.connect(0, "fe_elemental_scoping")

    dpf_workflow = dpf.Workflow()
    dpf_workflow.add_operator(forward)
    dpf_workflow.add_operator(forward_type)

    dpf_workflow.set_output_name("contour", forward, 0)
    dpf_workflow.set_output_name("contour_gfx_type", forward_type, 0)
    workflow_id = dpf_workflow.record('wf_id', False)
    this = Tree.FirstActiveObject
    this.WorkflowId = workflow_id

@greschd @roosre A basic evaluation with the python result works when using --no-dependencies.
