axolotl 0.8.0.dev0

LLM Trainer

Axolotl is a tool designed to streamline post-training for various AI models. Post-training refers to any modifications or additional training performed on pre-trained models - including full model fine-tuning, parameter-efficient tuning (like LoRA and QLoRA), supervised fine-tuning (SFT), instruction tuning, and alignment techniques. With support for multiple model architectures and training configurations, Axolotl makes it easy to get started with these techniques.

Axolotl is designed to work with YAML config files that contain everything you need to preprocess a dataset, train or fine-tune a model, run model inference or evaluation, and much more.

Features:

• Train various Huggingface models such as llama, pythia, falcon, mpt
• Supports fullfinetune, lora, qlora, relora, and gptq
• Customize configurations using a simple yaml file or CLI overwrite
• Load different dataset formats, use custom formats, or bring your own tokenized datasets
• Integrated with xformers, flash attention, liger kernel, rope scaling, and multipacking
• Works with single GPU or multiple GPUs via FSDP or Deepspeed
• Easily run with Docker locally or on the cloud
• Log results and optionally checkpoints to wandb, mlflow or Comet
• And more!

🚀 Quick Start

Requirements:

• NVIDIA GPU (Ampere or newer for bf16 and Flash Attention) or AMD GPU
• Python 3.11
• PyTorch ≥2.4.1

Installation

pip3 install --no-build-isolation axolotl[flash-attn,deepspeed]

# Download example axolotl configs, deepspeed configs
axolotl fetch examples
axolotl fetch deepspeed_configs  # OPTIONAL

Other installation approaches are described here.

Your First Fine-tune

# Fetch axolotl examples
axolotl fetch examples

# Or, specify a custom path
axolotl fetch examples --dest path/to/folder

# Train a model using LoRA
axolotl train examples/llama-3/lora-1b.yml
