export

name	export
description	Export a PyTorch model to .pte format for ExecuTorch. Use when converting models, lowering to edge, or generating .pte files.

Export

Basic pattern

from executorch.exir import to_edge_transform_and_lower
from torch.export import export

exported = export(model.eval(), example_inputs)
edge = to_edge_transform_and_lower(exported)
with open("model.pte", "wb") as f:
    f.write(edge.to_executorch().buffer)

Model-specific scripts

Debugging

• Draft export: export(model, inputs, strict=False)
• tlparse: TORCH_LOGS="+dynamo,+export" python script.py 2>&1 | tlparse
