## API Examples/Simple Tools
[examples/writer.py](https://github.com/ggerganov/llama.cpp/blob/master/gguf-py/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.
[scripts/gguf-dump.py](https://github.com/ggerganov/llama.cpp/blob/master/gguf-py/scripts/gguf-dump.py) — Dumps a GGUF file's metadata to the console.
[scripts/gguf-set-metadata.py](https://github.com/ggerganov/llama.cpp/blob/master/gguf-py/scripts/gguf-set-metadata.py) — Allows changing simple metadata values in a GGUF file by key.
[scripts/gguf-convert-endian.py](https://github.com/ggerganov/llama.cpp/blob/master/gguf-py/scripts/gguf-convert-endian.py) — Allows converting the endianness of GGUF files.
[scripts/gguf-new-metadata.py](https://github.com/ggerganov/llama.cpp/blob/master/gguf-py/scripts/gguf-new-metadata.py) — Copies a GGUF file with added/modified/removed metadata values.
## Development
Maintainers who participate in development of this package are advised to install it in editable mode:
```sh
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:
```sh
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.
```sh
git tag -a gguf-v1.0.0 -m "Version 1.0 release"
```
3. Push the tags.
```sh
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:
```sh
pip install build twine
```
Then, follow these steps to release a new version:
1. Bump the version in `pyproject.toml`.
2. Build the package:
```sh
python -m build
```
3. Upload the generated distribution archives:
```sh
python -m twine upload dist/*
```
## TODO
- [ ] Add tests
- [ ] Include conversion scripts as command line entry points in this package.
