Description

Question

The ONNX 1.18.0 documentation says that for operator SplitToSequence:

‘split’ must contain only positive numbers.

Why are zeros not allowed? The semantics for zeros seems unambiguous, and it seems like they should be allowed per the principle of least surprise.

Contributor guide

Research direction
Review the ONNX SplitToSequence operator specification and the rationale for requiring positive numbers; check for potential edge cases where zero could cause ambiguous behavior (e.g., splitting into zero length sequences) and examine discussions in the issue comments or related PRs.
