What changed
ONNX Resize distinguishes an omitted
axesattribute (resize all dimensions) from an explicitly emptyaxeslist (resize no dimensions). The frontend previously treated both as omitted and attempted to construct an all-axes Interpolate with an empty scale vector, causing valid models to fail shape validation.When
axesis present and empty, return the data output directly. Add an opset 18 regression test using a zero-length scales input and assert that the output equals the input.Fixes #39196
