Auxiliary Methods - CaptureVisionRouter Class

Method Description
set_global_intra_op_num_threads Sets the global number of threads used internally for model execution.
append_dl_model_buffer Appends a deep learning model to the memory buffer.
clear_dl_model_buffers Clears all deep learning models from buffer to free up memory.
append_model_buffer Deprecated. Will be removed in future versions. Use append_dl_model_buffer instead.

set_global_intra_op_num_threads

Sets the global number of threads used internally for model execution.

@staticmethod
def set_global_intra_op_num_threads(intra_op_num_threads: int) -> None

Parameters

intra_op_num_threads (int): Number of threads used internally for model execution. Valid range: [0, 256]. If the value is outside the range [0, 256], it will be treated as 0 (default).

Remarks

  • Introduced in Dynamsoft Barcode Reader SDK version 11.2.1000 and Dynamsoft Capture Vision version 3.2.1000.

append_dl_model_buffer

Appends a deep learning model to the memory buffer.

@staticmethod
def append_dl_model_buffer(model_name: str, model_buffer: bytes, max_model_instances: int) -> Tuple[int, str]

Parameters

model_name (str): The name of the model.

model_buffer (bytes): The bytes of the model.

max_model_instances (int): The max instances created for the model.

Return Value

A tuple containing following elements:

  • error_code (int): The error code indicating the status of the operation.
  • error_message (str): A descriptive message explaining the error.

Remarks

  • Introduced in Dynamsoft Barcode Reader SDK version 11.2.1000 and Dynamsoft Capture Vision version 3.2.1000.

clear_dl_model_buffers

Clears all deep learning models from buffer to free up memory.

@staticmethod
def clear_dl_model_buffers() -> None

Remarks

  • After calling this function, all CaptureVisionRouter instances created before the function call will not be able to use model-related features.

  • Introduced in Dynamsoft Barcode Reader SDK version 11.2.1000 and Dynamsoft Capture Vision version 3.2.1000.

append_model_buffer

Deprecated. Will be removed in future versions. Use append_dl_model_buffer instead.

Remarks

  • Deprecated in Dynamsoft Barcode Reader SDK version 11.2.1000 and Dynamsoft Capture Vision version 3.2.1000.
