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.

- 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.
- I do not use
onnx.utils.extractor.extract_model
because it is very slow and I implement my own model separation logic.
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 sne4onnx
1-2. Docker
https://github.com/PINTO0309/simple-onnx-processing-tools#docker
2. CLI Usage
$ sne4onnx -h
usage:
sne4onnx [-h]
-if INPUT_ONNX_FILE_PATH
-ion INPUT_OP_NAMES
-oon OUTPUT_OP_NAMES
[-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.
-ion INPUT_OP_NAMES [INPUT_OP_NAMES ...], --input_op_names INPUT_OP_NAMES [INPUT_OP_NAMES ...]
List of OP names to specify for the input layer of the model.
e.g. --input_op_names aaa bbb ccc
-oon OUTPUT_OP_NAMES [OUTPUT_OP_NAMES ...], --output_op_names OUTPUT_OP_NAMES [OUTPUT_OP_NAMES ...]
List of OP names to specify for the output layer of the model.
e.g. --output_op_names ddd eee fff
-of OUTPUT_ONNX_FILE_PATH, --output_onnx_file_path OUTPUT_ONNX_FILE_PATH
Output onnx file path. If not specified, extracted.onnx is output.
-n, --non_verbose
Do not show all information logs. Only error logs are displayed.
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] = '',
non_verbose: Optional[bool] = False
) -> onnx.onnx_ml_pb2.ModelProto
Parameters
----------
input_op_names: List[str]
List of OP names to specify for the input layer of the model.
e.g. ['aaa','bbb','ccc']
output_op_names: List[str]
List of OP names to specify for the output layer of the model.
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: ''
non_verbose: Optional[bool]
Do not show all information logs. Only error logs are displayed.
Default: False
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
6-1. Pre-extraction
6-2. Extraction
$ sne4onnx \
