1. Setup

1-1. HostPC

### option
$ echo export PATH="~/.local/bin:$PATH" >> ~/.bashrc \
&& source ~/.bashrc

### run
$ pip install -U onnx \
&& python3 -m pip install -U onnx_graphsurgeon --index-url https://pypi.ngc.nvidia.com \
&& pip install -U svs4onnx

1-2. Docker

https://github.com/PINTO0309/simple-onnx-processing-tools#docker

2. CLI Usage

$ svs4onnx -h

usage:
    svs4onnx [-h]
    -if INPUT_ONNX_FILE_PATH
    -fovn FROM_OUTPUT_VARIABLE_NAME
    -tivn TO_INPUT_VARIABLE_NAME
    -of OUTPUT_ONNX_FILE_PATH
    [-n]

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

  -if INPUT_ONNX_FILE_PATH, --input_onnx_file_path INPUT_ONNX_FILE_PATH
        Input onnx file path.

  -fovn FROM_OUTPUT_VARIABLE_NAME, --from_output_variable_name FROM_OUTPUT_VARIABLE_NAME
        Output variable name of the connection change source.
        e.g.
        --from_output_variable_name "output1"

  -tivn TO_INPUT_VARIABLE_NAME, --to_input_variable_name TO_INPUT_VARIABLE_NAME
        Input variable name of connection change destination.
        e.g.
        --to_input_variable_name "input1"

  -of OUTPUT_ONNX_FILE_PATH, --output_onnx_file_path OUTPUT_ONNX_FILE_PATH
        Output onnx file path.

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

3. In-script Usage

>>> from svs4onnx import variable_switch
>>> help(variable_switch)

Help on function variable_switch in module svs4onnx.onnx_model_variable_switch:

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

    Parameters
    ----------
    from_output_variable_name: str
        Output variable name of the connection change source.
        e.g.
        output_op_names = "output1"

    to_input_variable_name: str
        Input variable name of connection change destination.
        e.g.
        output_op_names = "input1"

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

    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.

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

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

    Returns
    -------
    variable_switched_graph: onnx.ModelProto
        onnx.ModelProto with variable switched

4. CLI Execution

$ svs4onnx \
--input_onnx_file_path movenet_multipose_lightning_192x256_nopost_tmp1.onnx \
--from_output_variable_name "cast1_output" \
--to_input_variable_name "StatefulPartitionedCall/strided_slice_21" \
--output_onnx_file_path movenet_multipose_lightning_192x256_nopost_tmp2.onnx

5. In-script Execution
