# Finetune Liquid Foundation Models 2 (LFM2) with Axolotl
|
|
|
|
[Liquid Foundation Models 2 (LFM2)](https://huggingface.co/collections/LiquidAI/lfm2-686d721927015b2ad73eaa38) are a family of small, open-weight models from [Liquid AI](https://www.liquid.ai/) focused on quality, speed, and memory efficiency. Liquid AI released text-only [LFM2](https://huggingface.co/collections/LiquidAI/lfm2-686d721927015b2ad73eaa38) and text+vision [LFM2-VL](https://huggingface.co/collections/LiquidAI/lfm2-vl-68963bbc84a610f7638d5ffa) models.
|
|
|
|
LFM2 features a new hybrid Liquid architecture with multiplicative gates, short-range convolutions, and grouped query attention, enabling fast training and inference.
|
|
|
|
This guide shows how to fine-tune both the LFM2 and LFM2-VL models with Axolotl.
|
|
|
|
Thanks to the team at LiquidAI for giving us early access to prepare for these releases.
|
|
|
|
## Getting Started
|
|
|
|
1. Install Axolotl following the [installation guide](https://docs.axolotl.ai/docs/installation.html).
|
|
|
|
Here is an example of how to install from pip:
|
|
```bash
|
|
# Ensure you have a compatible version of Pytorch installed
|
|
pip3 install packaging setuptools wheel ninja
|
|
pip3 install --no-build-isolation 'axolotl[flash-attn]>=0.12.0'
|
|
```
|
|
|
|
2. Run one of the finetuning examples below.
|
|
|
|
**LFM2**
|
|
```bash
|
|
# FFT SFT (1x48GB @ 25GiB)
|
|
axolotl train examples/LiquidAI/lfm2-350m-fft.yaml
|
|
```
|
|
|
|
**LFM2-VL**
|
|
```bash
|
|
# LoRA SFT (1x48GB @ 2.7GiB)
|
|
axolotl train examples/LiquidAI/lfm2-vl-lora.yaml
|
|
```
|
|
|
|
**LFM2-MoE**
|
|
```bash
|
|
pip install git+https://github.com/huggingface/transformers.git@0c9a72e4576fe4c84077f066e585129c97bfd4e6
|
|
|
|
# LoRA SFT (1x48GB @ 16.2GiB)
|
|
axolotl train examples/LiquidAI/lfm2-8b-a1b-lora.yaml
|
|
```
|
|
|
|
### TIPS
|
|
|
|
- **Installation Error**: If you encounter `ImportError: ... undefined symbol ...` or `ModuleNotFoundError: No module named 'causal_conv1d_cuda'`, the `causal-conv1d` package may have been installed incorrectly. Try uninstalling it:
|
|
```bash
|
|
pip uninstall -y causal-conv1d
|
|
```
|
|
|
|
- **Dataset Loading**: Read more on how to load your own dataset in our [documentation](https://docs.axolotl.ai/docs/dataset_loading.html).
|
|
- **Dataset Formats**:
|
|
- For LFM2 models, the dataset format follows the OpenAI Messages format as seen [here](https://docs.axolotl.ai/docs/dataset-formats/conversation.html#chat_template).
|
|
- For LFM2-VL models, Axolotl follows the multi-content Messages format. See our [Multimodal docs](https://docs.axolotl.ai/docs/multimodal.html#dataset-format) for details.
