32 should only be called by command line tools and unit test code that tests 

33 this function. 

34 

35 Build and optionally save pipeline definition. 

36 

37 Returns the pipeline instance that was built, for testing and for using 

38 this function with other script functions. 

39 

40 Parameters 

41 ---------- 

42 order_pipeline : `bool` 

43 If true, order tasks in pipeline based on their data dependencies, 

44 ordering is performed as last step before saving or executing pipeline. 

45 pipeline_actions : `list` [`PipelineAction`]] or `PipelineAction` 

46 A list of pipeline actions in the order they should be executed. 

47 pipeline_dot : `str` 

48 Path location for storing GraphViz DOT representation of a pipeline. 

49 pipeline : `str` 

50 Path location of a pipeline definition file in YAML format. 

51 save_pipeline : `str` 

52 Path location for storing resulting pipeline definition in YAML format. 

53 show : `lsst.ctrl.mpexec.showInfo.ShowInfo` 

54 Descriptions of what to dump to stdout. 

55 kwargs : `dict` [`str`, `str`] 

56 Ignored; click commands may accept options for more than one script 

57 function and pass all the option kwargs to each of the script functions 

58 which ingore these unused kwargs. 

59 

60 Returns 

61 ------- 

62 pipeline : `lsst.pipe.base.Pipeline` 

63 The pipeline instance that was built. 

64 

65 Raises 

66 ------ 

67 Exception 

68 Raised if there is a failure building the pipeline.
