sne4onnx

A very simple tool for situations where optimization with onnx-simplifier would exceed the Protocol Buffers upper file size limit of 2GB, or simply to separate onnx files to any size you want. Simple Network Extraction for ONNX.

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

Key concept

If INPUT OP name and OUTPUT OP name are specified, the onnx graph within the range of the specified OP name is extracted and .onnx is generated.
Change backend to onnx.utils.Extractor.extract_model so that onnx.ModelProto can be specified as input.

1. Setup

1-1. HostPC

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

### run
$ pip install -U onnx \
&& pip install -U sne4onnx

1-2. Docker

### docker pull
$ docker pull pinto0309/sne4onnx:latest

### docker build
$ docker build -t pinto0309/sne4onnx:latest .

### docker run
$ docker run --rm -it -v `pwd`:/workdir pinto0309/sne4onnx:latest
$ cd /workdir

2. CLI Usage

$ sne4onnx -h

usage:
    sne4onnx [-h]
    --input_onnx_file_path INPUT_ONNX_FILE_PATH
    --input_op_names INPUT_OP_NAMES
    --output_op_names OUTPUT_OP_NAMES
    [--output_onnx_file_path OUTPUT_ONNX_FILE_PATH]

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

  --input_onnx_file_path INPUT_ONNX_FILE_PATH
        Input onnx file path.

  --input_op_names INPUT_OP_NAMES
        List of OP names to specify for the input layer of the model.
        Specify the name of the OP, separated by commas.
        e.g. --input_op_names aaa,bbb,ccc

  --output_op_names OUTPUT_OP_NAMES
        List of OP names to specify for the output layer of the model.
        Specify the name of the OP, separated by commas.
        e.g. --output_op_names ddd,eee,fff

  --output_onnx_file_path OUTPUT_ONNX_FILE_PATH
        Output onnx file path. If not specified, extracted.onnx is output.

3. In-script Usage

$ python
>>> from sne4onnx import extraction
>>> help(extraction)

Help on function extraction in module sne4onnx.onnx_network_extraction:

extraction(
    input_op_names: List[str],
    output_op_names: List[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] = ''
) -> onnx.onnx_ml_pb2.ModelProto

    Parameters
    ----------
    input_op_names: List[str]
        List of OP names to specify for the input layer of the model.
        Specify the name of the OP, separated by commas.
        e.g. ['aaa','bbb','ccc']

    output_op_names: List[str]
        List of OP names to specify for the output layer of the model.
        Specify the name of the OP, separated by commas.
        e.g. ['ddd','eee','fff']

    input_onnx_file_path: Optional[str]
        Input onnx file path.
        Either input_onnx_file_path or onnx_graph must be specified.
        onnx_graph If specified, ignore input_onnx_file_path and process onnx_graph.

    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, .onnx is not output.
        Default: ''

    Returns
    -------
    extracted_graph: onnx.ModelProto
        Extracted onnx ModelProto

4. CLI Execution

$ sne4onnx \
--input_onnx_file_path input.onnx \
--input_op_names aaa,bbb,ccc \
--output_op_names ddd,eee,fff \
--output_onnx_file_path output.onnx

5. In-script Execution

5-1. Use ONNX files

from sne4onnx import extraction

extracted_graph = extraction(
  input_op_names=['aaa', 'bbb', 'ccc'],
  output_op_names=['ddd', 'eee', 'fff'],
  input_onnx_file_path='input.onnx',
  output_onnx_file_path='output.onnx',
)

5-2. Use onnx.ModelProto

from sne4onnx import extraction

extracted_graph = extraction(
  input_op_names=['aaa', 'bbb', 'ccc'],
  output_op_names=['ddd', 'eee', 'fff'],
  onnx_graph=graph,
  output_onnx_file_path='output.onnx',
)

6. Samples
