AttributeError: newbyteorder was removed from scalar types in NumPy 2.0. Use sc.view(sc.dtype.newbyteorder(order)) instead.

AFAIK the same code is also present in gguf_new_metadata and other python scripts. So probably better to do a full pass to change it in other places.

And btw these scripts are not actually part of gguf-py, they are more like "examples"

Hey, sorry, this PR reminded me I had a lot of unsubmitted code locally, made #11909 that supercedes this...

i have a bunch of guff models downloaded with ollama which their file doesn't have the name of the model, instead they are like: sha256-170370233dd5c5415250a2ecd5c71586352850729062ccef1496385647293868 sha256-22a849aafe3ded20e9b6551b02684d8fa911537c35895dd2a1bf9eb70da8f69e

and i was looking for a tool that i could give a .guff file as input and get info about the model, something like the UNIX file or ffprobe command, and i stumbled upon this.

Closing the issue in favor of #11909
