void HComponentTraining.ReadTrainingComponents(string fileName)

def read_training_components(file_name: str) -> HHandle

Description

The operator read_training_componentsread_training_componentsReadTrainingComponentsReadTrainingComponentsread_training_components reads a component training result, which has been written with write_training_componentswrite_training_componentsWriteTrainingComponentsWriteTrainingComponentswrite_training_components, from the file FileNameFileNameFileNamefileNamefile_name and returns it in ComponentTrainingIDComponentTrainingIDComponentTrainingIDcomponentTrainingIDcomponent_training_id. The default HALCON file extension for the component training result is 'ct'.

Execution Information

• Multithreading type: reentrant (runs in parallel with non-exclusive operators).
• Multithreading scope: global (may be called from any thread).
• Processed without parallelization.

This operator returns a handle. Note that the state of an instance of this handle type may be changed by specific operators even though the handle is used as an input parameter by those operators.

Parameters

FileNameFileNameFileNamefileNamefile_name (input_control)  filename.read → HTuplestrHTupleHtuple (string) (string) (HString) (char*)

File name.

File extension: .ct

ComponentTrainingIDComponentTrainingIDComponentTrainingIDcomponentTrainingIDcomponent_training_id (output_control)  component_training → HComponentTraining, HTupleHHandleHTupleHtuple (handle) (IntPtr) (HHandle) (handle)

Handle of the training result.

Result

If the file name is valid, the operator read_training_componentsread_training_componentsReadTrainingComponentsReadTrainingComponentsread_training_components returns the value 2 ( H_MSG_TRUE) . If necessary, an exception is raised.
