Summary

Voyager SDK 1.6.0 quantizer rejects ONNX models that have a fan-out fork close to
the input (e.g., a tensor consumed by multiple parallel paths early in the graph)
with the error:


axelera.compiler.exceptions.QuantizationError: Input model cannot be quantized because the core graph has several inputs that are not currently supported by Quantizer.
