Description

In pytorch

...
norm = torch.norm(x, p=2)
return x / norm

I converted this model into onnx and tried to convert to ncnn, got error "Unsupported reduction axes !"
How to pass model conversion by modify pytorch script?
Thanks.

Research direction

Start with the reported PyTorch expression using torch.norm(x, p=2) and reproduce the ONNX-to-ncnn conversion that emits "Unsupported reduction axes !". The issue does not name a source file, test, model, or supported-axis reference; done would require a confirmed conversion workaround or a clarified, reproducible report.
