What? ExecuTorch is a new PyTorch library that makes it easier to support Torch models locally. We will integrate with their “send to” functionality, which enables a direct export from Python-based Torch models to the .sentis intermediary representation. This enables direct model import into Unity and removes the need to convert to ONNX.

Why? Today, Unity users must convert Python-based Torch models to ONNX and then import them into Sentis. This adds an additional complex step to the import process, and the ONNX conversion can have compatibility issues. By staying close to the source Torch format, we can open up far more Sentis-compatible AI models from the PyTorch community.

*Note: Don’t worry: we will not remove support for ONNX import.
