2. CLI Usage

$ sic4onnx -h

usage:
    sic4onnx [-h]
    --input_onnx_file_path INPUT_ONNX_FILE_PATH
    --output_onnx_file_path OUTPUT_ONNX_FILE_PATH
    --ir_version IR_VERSION
    [--non_verbose]

optional arguments:
  -h, --help
        show this help message and exit

  --input_onnx_file_path INPUT_ONNX_FILE_PATH
        Input onnx file path.

  --output_onnx_file_path OUTPUT_ONNX_FILE_PATH
        Output onnx file path.

  --ir_version IR_VERSION
        IR version number to be changed. e.g. --ir_version 8
        https://github.com/onnx/onnx/blob/main/onnx/version_converter.py#L12-L160

  --non_verbose
        Do not show all information logs. Only error logs are displayed.

3. In-script Usage

$ python
>>> from sic4onnx import irchange
>>> help(irchange)
Help on function change in module sic4onnx.onnx_irversion_change:

change(
  ir_version: int,
  input_onnx_file_path: Union[str, NoneType] = '',
  output_onnx_file_path: Union[str, NoneType] = '',
  onnx_graph: Union[onnx.onnx_ml_pb2.ModelProto, NoneType] = None,
  non_verbose: Union[bool, NoneType] = False
) -> onnx.onnx_ml_pb2.ModelProto

    Parameters
    ----------
    ir_version: int
        IR version number to be changed.
        e.g. --ir_version 8
        https://github.com/onnx/onnx/blob/main/onnx/version_converter.py#L12-L160

    input_onnx_file_path: Optional[str]
        Input onnx file path.
        Either input_onnx_file_path or onnx_graph must be specified.

    output_onnx_file_path: Optional[str]
        Output onnx file path.
        If output_onnx_file_path is not specified, no .onnx file is output.

    onnx_graph: Optional[onnx.ModelProto]
        onnx.ModelProto.
        Either input_onnx_file_path or onnx_graph must be specified.
        onnx_graph If specified, ignore input_onnx_file_path and process onnx_graph.

    non_verbose: Optional[bool]
        Do not show all information logs. Only error logs are displayed.
        Default: False

    Returns
    -------
    ir_changed_graph: onnx.ModelProto
        IR version changed onnx ModelProto

4. CLI Execution

$ sic4onnx \
--input_onnx_file_path input.onnx \
--output_onnx_file_path output.onnx \
--ir_version 8

5. In-script Execution

from sic4onnx import irchange

ir_changed_graph = irchange(
    onnx_graph=graph,
    ir_version=8,
    non_verbose=True,
)
