pytorchのスライス代入操作をonnxに変換する際にScatterNDならないようにするサンプル

Overview

pytorch_remove_ScatterND

pytorchのスライス代入操作をonnxに変換する際にScatterNDならないようにするサンプル。
スライスしたtensorにそのまま代入してしまうとScatterNDになるため、計算結果をcatで新しいtensorにする。

python version

Python 3.8.11

setup

pip install -r requirements.txt

usage

python convertonnx.py

scatternd_model.onnxとcat_model.onnxが作成されるのでNetronなどで確認。

src

scatterndmodel.py

ScatterNDになるような演算を含むモデル

catmodel.py

ScatterNDを使わずscatterndmodelと同じ結果になるようにしたモデル

Netron
