Workflows kinds¶

In workflows - some values are not possible to be defined at the moment when workflow definition is created. That's why execution engine supports selectors - which define references to step outputs or workflow run inputs. To hint execution engine what is going to be provided once reference is resolved we need a simple type system - that's what we call kinds.

List of workflows kinds¶

• string: String value
• boolean: Boolean flag
• Batch[parent_id]: Identifier of parent for step output
• Batch[string]: Batch of string values
• Batch[keypoint_detection_prediction]: 'predictions' key from Roboflow keypoint detection model output
• Batch[object_detection_prediction]: 'predictions' key from Roboflow object detection model output
• float_zero_to_one: float value in range [0.0, 1.0]
• roboflow_model_id: Roboflow model id
• Batch[image_metadata]: Dictionary with image metadata required by supervision
• Batch[bar_code_detection]: Roboflow prediction with barcode detection
• Batch[instance_segmentation_prediction]: 'predictions' key from Roboflow instance segmentation model output
• list_of_values: List of values of any types
• Batch[top_class]: Batch of string values representing top class predicted by classification model
• roboflow_project: Roboflow project name
• dictionary: Dictionary
• float: Float value
• Batch[image]: Image in workflows
• integer: Integer value
• Batch[dictionary]: Batch of dictionaries
• Batch[prediction_type]: String value with type of prediction
• *: Equivalent of any element
