Pedro Cuenca 88bfee1429 model: add GLM 5.2 Indexer support (#25407)
* Start building graph - reuse deepseek32

* Enable kv cache and rotation for glm_dsa architecture

Just follow Deepseek 3.2 for now.

* Reuse prev_top_k for "shared" indexer layers

* GLM 5.2 uses LLAMA_ROPE_TYPE_NORM for the indexer.

This is transformers' `apply_rotary_pos_emb_interleave`

* Default indexer types to GLM pattern

Previous converted GGUFs like https://huggingface.co/unsloth/GLM-5.2-GGUF write indexer weights to _all_ layers, even if they are only required for "full" types. This PR relies on a new key "%s.attention.indexer.types"; if absent, it will use the default GLM 5.2 schedule as defined in https://huggingface.co/zai-org/GLM-5.2/blob/main/config.json#L26.

Note that conversion is not saving this key yet.

* Save indexer types to gguf, restore on load

* Use ggml_lightning_indexer when cparams.fused_lid

* GLM 5 and 5.1 use full indexers

* Fix indentation

* Ensure array is zero-filled

* Prefer explicit std::fill

* Assert prev_top_k exists for shared indexer

gguf

This is a Python package for writing binary files in the GGUF (GGML Universal File) format.

See convert_hf_to_gguf.py as an example for its usage.

Installation

pip install gguf

Optionally, you can install gguf with the extra 'gui' to enable the visual GGUF editor.

pip install gguf[gui]

API Examples/Simple Tools

examples/writer.py — Generates example.gguf in the current directory to demonstrate generating a GGUF file. Note that this file cannot be used as a model.

examples/reader.py — Extracts and displays key-value pairs and tensor details from a GGUF file in a readable format.

gguf/scripts/gguf_dump.py — Dumps a GGUF file's metadata to the console.

gguf/scripts/gguf_set_metadata.py — Allows changing simple metadata values in a GGUF file by key.

gguf/scripts/gguf_convert_endian.py — Allows converting the endianness of GGUF files.

gguf/scripts/gguf_new_metadata.py — Copies a GGUF file with added/modified/removed metadata values.

gguf/scripts/gguf_editor_gui.py — Allows for viewing, editing, adding, or removing metadata values within a GGUF file as well as viewing its tensors with a Qt interface.

Development

Maintainers who participate in development of this package are advised to install it in editable mode:

cd /path/to/llama.cpp/gguf-py

pip install --editable .

Note: This may require to upgrade your Pip installation, with a message saying that editable installation currently requires setup.py. In this case, upgrade Pip to the latest:

pip install --upgrade pip

Automatic publishing with CI

There's a GitHub workflow to make a release automatically upon creation of tags in a specified format.

  1. Bump the version in pyproject.toml.
  2. Create a tag named gguf-vx.x.x where x.x.x is the semantic version number.
git tag -a gguf-v1.0.0 -m "Version 1.0 release"
  1. Push the tags.
git push origin --tags

Manual publishing

If you want to publish the package manually for any reason, you need to have twine and build installed:

pip install build twine

Then, follow these steps to release a new version:

  1. Bump the version in pyproject.toml.
  2. Build the package:
python -m build
  1. Upload the generated distribution archives:
python -m twine upload dist/*

Run Unit Tests

From root of this repository you can run this command to run all the unit tests

python -m unittest discover ./gguf-py -v

TODO

  • Include conversion scripts as command line entry points in this package.
