# Finetune Gemma-3n with Axolotl
|
||||
|
||||
## Requirements
|
||||
Gemma-3n is a family of multimodal models from Google found on [HuggingFace](https://huggingface.co/collections/google/gemma-3n-685065323f5984ef315c93f4). This guide shows how to fine-tune it with Axolotl.
|
||||
|
||||
In addition to Axolotl's requirements, Gemma-3n requires
|
||||
## Getting started
|
||||
|
||||
```
|
||||
pip3 install timm
|
||||
1. Install Axolotl following the [installation guide](https://docs.axolotl.ai/docs/installation.html). You need to install from main as Gemma3n is only on nightly or use our latest [Docker images](https://docs.axolotl.ai/docs/docker.html).
|
||||
|
||||
Here is an example of how to install from main for pip:
|
||||
|
||||
```bash
|
||||
# Ensure you have Pytorch installed (Pytorch 2.6.0 min recommended)
|
||||
git clone https://github.com/axolotl-ai-cloud/axolotl.git
|
||||
cd axolotl
|
||||
|
||||
pip3 install packaging==23.2 setuptools==75.8.0 wheel ninja
|
||||
pip3 install --no-build-isolation -e '.[flash-attn]'
|
||||
```
|
||||
|
||||
If you will load audio datasets, please also install
|
||||
2. In addition to Axolotl's requirements, Gemma-3n requires:
|
||||
|
||||
```
|
||||
pip3 install librosa
|
||||
```bash
|
||||
pip3 install timm==1.0.17
|
||||
|
||||
# for loading audio data
|
||||
pip3 install librosa==0.11.0
|
||||
```
|
||||
|
||||
## Usage
|
||||
3. Run the finetuning example:
|
||||
|
||||
See example configs and the [multimodal doc](https://docs.axolotl.ai/docs/multimodal.html).
|
||||
```bash
|
||||
# text only
|
||||
axolotl train examples/gemma3n/gemma-3n-e2b-qlora.yml
|
||||
|
||||
# text + vision
|
||||
axolotl train examples/gemma3n/gemma-3n-e2b-vision-qlora.yml
|
||||
|
||||
# text + vision + audio
|
||||
axolotl train examples/gemma3n/gemma-3n-e2b-vision-audio-qlora.yml
|
||||
```
|
||||
|
||||
Let us know how it goes. Happy finetuning! 🚀
|
||||
|
||||
WARNING: The loss and grad norm will be much higher than normal. We suspect this to be inherent to the model as of the moment. If anyone would like to submit a fix for this, we are happy to take a look.
|
||||
|
||||
### TIPS
|
||||
|
||||
- You can run a full finetuning by removing the `adapter: qlora` and `load_in_4bit: true` from the config.
|
||||
- Read more on how to load your own dataset at [docs](https://docs.axolotl.ai/docs/dataset_loading.html).
|
||||
- The text dataset format follows the OpenAI Messages format as seen [here](https://docs.axolotl.ai/docs/dataset-formats/conversation.html#chat_template).
|
||||
- The multimodal dataset format follows the OpenAI multi-content Messages format as seen [here](https://docs.axolotl.ai/docs/multimodal.html#dataset-format).

### Thinking
|
||||
|
||||
MistralAI has released their [2507](https://huggingface.co/mistralai/Magistral-Small-2507) model with thinking capabilities. The model requires the multi-content dataset format with support for an extra `role: thinking` within system and assistant messages.
|
||||
|
||||
Example format:
|
||||
|
||||
```json
|
||||
{
|
||||
"messages": [
|
||||
{"role": "system", "content": [{ "type": "text", "text": "{SYSTEM_PROMPT}"}]},
|
||||
{"role": "user", "content": [{ "type": "text", "text": "..."}]},
|
||||
{"role": "assistant", "content": [{ "type": "thinking", "thinking": "..."}, { "type": "text", "text": "..." }]},
|
||||
],
|
||||
}
|
||||
```
|
||||
|
||||
Example config: `./magistral-small-think-qlora.yaml`.
|
||||
|
||||
The `thinking` section also supports an optional arg `closed: bool` (`True` default) which controls adding the closing `[/THINK]` tag.
|
||||
|
||||
Limitations:
|
||||
- You cannot mix `content: str` with `content: list[dict]` as the `dataset.load_dataset` may complain about different types for `content` key.
|
||||
- This mode does not work with custom `train_detail` and `training` at the moment.
|
||||
|
||||
### TIPS
|
||||
|
||||
- We recommend adding the same/similar SystemPrompt that the model is tuned for. You can find this within the repo's files titled `SYSTEM_PROMPT.txt`.
|
||||
- For inference, the official MistralAI team recommends `top_p: 0.95` and `temperature: 0.7` with `max_tokens: 40960`.
|
||||
- You can run a full finetuning by removing the `adapter: qlora` and `load_in_4bit: true` from the config.
|
||||
- Read more on how to load your own dataset at [docs](https://docs.axolotl.ai/docs/dataset_loading.html).
|
||||
- The dataset format follows the OpenAI Messages format as seen [here](https://docs.axolotl.ai/docs/dataset-formats/conversation.html#chat_template).

# Finetune Voxtral with Axolotl
|
||||
|
||||
Voxtral is a [3B](https://huggingface.co/mistralai/Voxtral-Mini-3B-2507)/[24B](https://huggingface.co/mistralai/Voxtral-Small-24B-2507) parameter opensource model from MistralAI found on HuggingFace. This guide shows how to fine-tune it with Axolotl.
|
||||
|
||||
Thanks to the team at MistralAI for giving us early access to prepare for this release.
|
||||
|
||||
## Getting started
|
||||
|
||||
1. Install Axolotl following the [installation guide](https://docs.axolotl.ai/docs/installation.html). You need to install from main as Voxtral is only on nightly or use our latest [Docker images](https://docs.axolotl.ai/docs/docker.html).
|
||||
|
||||
Here is an example of how to install from main for pip:
|
||||
|
||||
```bash
|
||||
# Ensure you have Pytorch installed (Pytorch 2.6.0 min)
|
||||
git clone https://github.com/axolotl-ai-cloud/axolotl.git
|
||||
cd axolotl
|
||||
|
||||
pip3 install packaging==23.2 setuptools==75.8.0 wheel ninja
|
||||
pip3 install --no-build-isolation -e '.[flash-attn]'
|
||||
```
|
||||
|
||||
2. Please install the below.
|
||||
|
||||
```bash
|
||||
# audio
|
||||
pip3 install librosa==0.11.0
|
||||
pip3 install 'mistral_common[audio]==1.8.3'
|
||||
```
|
||||
|
||||
3. Run the finetuning example:
|
||||
|
||||
```bash
|
||||
# text only
|
||||
axolotl train examples/voxtral/voxtral-mini-qlora.yml
|
||||
|
||||
# text + audio
|
||||
axolotl train examples/voxtral/voxtral-mini-audio-qlora.yml
|
||||
```
|
||||
|
||||
These configs use about 4.8 GB VRAM.
|
||||
|
||||
Let us know how it goes. Happy finetuning! 🚀
|
||||
|
||||
### TIPS
|
||||
|
||||
- For inference, the official MistralAI team recommends `temperature: 0.2` and `top_p: 0.95` for audio understanding and `temperature: 0.0` for transcription.
|
||||
- You can run a full finetuning by removing the `adapter: qlora` and `load_in_4bit: true` from the config.
|
||||
- Read more on how to load your own dataset at [docs](https://docs.axolotl.ai/docs/dataset_loading.html).
|
||||
- The text dataset format follows the OpenAI Messages format as seen [here](https://docs.axolotl.ai/docs/dataset-formats/conversation.html#chat_template).
|
||||
- The multimodal dataset format follows the OpenAI multi-content Messages format as seen [here](https://docs.axolotl.ai/docs/multimodal.html#dataset-format).
|
||||
|
||||
|
||||
## Optimization Guides
|
||||
|
||||
- [Multi-GPU Training](https://docs.axolotl.ai/docs/multi-gpu.html)
|
||||
- [Multi-Node Training](https://docs.axolotl.ai/docs/multi-node.html)
|
||||
- [LoRA Optimizations](https://docs.axolotl.ai/docs/lora_optims.html)
|
||||
|
||||
## Limitations
|
||||
|
||||
We only support the `mistral-common` tokenizer for Supervised Fine-tuning at the moment and for `type: chat_template` only.
|
||||
|
||||
In addition, we do not support overriding tokens yet.

## Future Work
|
||||
|
||||
- Add parity to Preference Tuning, RL, etc.
|
||||
- Add parity to other tokenizer configs like overriding tokens.

Can be either:

- A string, the *model id* of a predefined tokenizer hosted inside a model repo on huggingface.co.
|

- A path to a *directory* containing the tokenizer config, for instance saved
|

using the [`MistralCommonTokenizer.tokenization_mistral_common.save_pretrained`] method, e.g.,
|
||||
`./my_model_directory/`.
|

mode (`ValidationMode`, *optional*, defaults to `ValidationMode.test`):
|
||||
Validation mode for the `MistralTokenizer` tokenizer.
|

Path to a directory in which a downloaded predefined tokenizer vocabulary files should be cached if the
|

standard cache should not be used.

Whether or not to force the (re-)download the vocabulary files and override the cached versions if they

||||
exist.
|

token (`str` or *bool*, *optional*):

The token to use as HTTP bearer authorization for remote files. If `True`, will use the token generated

Whether or not to only rely on local files and not to attempt to download any files.
|
||||
revision (`str`, *optional*, defaults to `"main"`):
|
||||
The specific model version to use. It can be a branch name, a tag name, or a commit id, since we use a
|
||||
git-based system for storing models and other artifacts on huggingface.co, so `revision` can be any
|
||||
identifier allowed by git.
|

max_length (`int`, *optional*):
|

Controls the maximum length to use by one of the truncation/padding parameters.
|

If left unset or set to `None`, this will use the predefined model maximum length if a maximum length
|

is required by one of the truncation/padding parameters. If the model has no specific maximum input
|

length (like XLNet) truncation/padding to a maximum length will be deactivated.

tokenization process.
