#### How to add custom prompts

  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>`.

Optionally, download some datasets, see [data/README.md](data/README.md)



### 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

  # local
  datasets:
    - path: json
      data_files: data.jsonl # or json
      type: alpaca # format from earlier
  ```

- 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
    - v_proj
  ```

### Train

Run
```bash
accelerate launch scripts/finetune.py configs/your_config.yml
```

#### Multi-GPU

You can optionally pre-tokenize dataset with the following before finetuning:
```bash
CUDA_VISIBLE_DEVICES="" accelerate ... --prepare_ds_only
```

##### Config

- llama FSDP
```yaml
fsdp:
  - full_shard
  - auto_wrap
fsdp_config:
  fsdp_offload_params: true
  fsdp_state_dict_type: FULL_STATE_DICT
  fsdp_transformer_layer_cls_to_wrap: LlamaDecoderLayer
```

- llama Deepspeed
```yaml
deepspeed: # path to config
```

##### Weights & Biases Logging

- wandb options
```yaml
wandb_mode:
wandb_project:
wandb_entity:
wandb_watch:
wandb_run_id:
wandb_log_model:
```

### Inference

Pass the appropriate flag to the train command:

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

### Merge LORA to base

Add below flag to train command above

```bash
--merge_lora --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 scripts/finetune.py ...
```

## Common Errors 🧰

> Cuda out of memory

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

> 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.
