# Axolotl

Axolotl is a tool designed to streamline the fine-tuning of various AI models, offering support for multiple configurations and architectures.

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 xformer, flash attention, 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
- And more!

#### How to add custom prompts

Using yaml. Example:
```yaml
datasets:
  - path: repo
    type:
      system_prompt: ""
      no_input_format: |-
        User: {instruction}<|end_of_turn|>
        Assistant:
      format: |-
        User: {instruction}
        {input}<|end_of_turn|>
        Assistant:
```

Using file:
1. Add your method to a file in [prompt_strategies](src/axolotl/prompt_strategies). Please see other files as example.
2. Use your custom file name as the dataset type `<prompt_strategies_file>.load_<load_fn>`.

#### How to use your custom pretokenized dataset

- Do not pass a `type:`
- Dataset must contain `input_ids`, `attention_mask`, `labels` in columns


### Config

See [examples](examples) for quick start. It is recommended to duplicate and modify to your needs. The most important options are:

- model
  ```yaml
  base_model: ./llama-7b-hf # local or huggingface repo
  ```
  Note: The code will load the right architecture.

- dataset
  ```yaml
  sequence_len: 2048 # max token length for prompt

  # huggingface repo
  datasets:
    - path: vicgalle/alpaca-gpt4
      type: alpaca # format from earlier

  # huggingface repo with specific configuration/subset
  datasets:
    - path: EleutherAI/pile
      name: enron_emails
      type: completion # format from earlier
      field: text # Optional[str] default: text, field to use for completion data

  # huggingface repo with multiple named configurations/subsets
  datasets:
    - path: bigcode/commitpackft
      name:
        - ruby
        - python
        - typescript
      type: ... # unimplemented custom format

  # local
  datasets:
    - path: data.jsonl # or json
      ds_type: json # see other options below
      type: alpaca
  ```

- loading
  ```yaml
  load_in_4bit: true
  load_in_8bit: true
  bf16: true # require >=ampere
  fp16: true
  tf32: true # require >=ampere
  bfloat16: true # require >=ampere, use instead of bf16 when you don't want AMP (automatic mixed precision)
  float16: true # use instead of fp16 when you don't want AMP
  ```
  Note: Repo does not do 4-bit quantization.

- lora
  ```yaml
  adapter: lora # qlora or leave blank for full finetune
  lora_r: 8
  lora_alpha: 16
  lora_dropout: 0.05
  lora_target_modules:
    - q_proj

  ```

### Train

Run
```bash
accelerate launch -m axolotl.cli.train your_config.yml
```

#### Multi-GPU

You can optionally pre-tokenize dataset with the following before finetuning:
```bash
CUDA_VISIBLE_DEVICES="" accelerate launch -m axolotl.cli.train your_config.yml --prepare_ds_only
```

##### Config

### Training with Deepspeed

Deepspeed is an optimization suite for multi-gpu systems allowing you to train much larger models than you
might typically be able to fit into your GPU's VRAM. More information about the various optimization types
for deepspeed is available at https://huggingface.co/docs/accelerate/main/en/usage_guides/deepspeed#what-is-integrated

We provide several default deepspeed JSON configurations for ZeRO stage 1, 2, and 3.

```shell
accelerate launch -m axolotl.cli.train examples/llama-2/config.py --deepspeed deepspeed/zero1.json
```

or

```yaml
deepspeed: deepspeed/zero1.json
```

### Inference

Pass the appropriate flag to the train command:

- Pretrained LORA:
  ```bash
  python -m axolotl.cli.inference examples/your_config.yml --lora_model_dir="./lora-output-dir"
  ```
- Full weights finetune:
  ```bash
  python -m axolotl.cli.inference examples/your_config.yml --base_model="./completed-model"
  ```
- Full weights finetune w/ a prompt from a text file:
  ```bash
  cat /tmp/prompt.txt | python -m axolotl.cli.inference examples/your_config.yml \
    --base_model="./completed-model" --prompter=None --load_in_8bit=True
  ```

### Merge LORA to base

Add below flag to train command above

```bash
python3 -m axolotl.cli.merge_lora examples/your_config.yml --lora_model_dir="./completed-model" --load_in_8bit=False --load_in_4bit=False
```

If you run out of CUDA memory, you can try to merge in system RAM with

```bash
CUDA_VISIBLE_DEVICES="" python3 -m axolotl.cli.merge_lora ...
```

## Common Errors 🧰

> If you encounter a 'Cuda out of memory' error, it means your GPU ran out of memory during the training process. Here's how to resolve it:

Please reduce any below
  - `micro_batch_size`
  - `eval_batch_size`
  - `gradient_accumulation_steps`
  - `sequence_len`

> `failed (exitcode: -9)`

Usually means your system has run out of system memory.
Similarly, you should consider reducing the same settings as when you run out of VRAM.
Additionally, look into upgrading your system RAM which should be simpler than GPU upgrades.

> RuntimeError: expected scalar type Float but found Half

Try set `fp16: true`

> NotImplementedError: No operator found for `memory_efficient_attention_forward` ...

Try to turn off xformers.

> accelerate config missing

It's safe to ignore it.

> NCCL Timeouts during training

See the [NCCL](docs/nccl.md) guide.
