	## Quickstart ⚡

	Get started with Axolotl in just a few steps! This quickstart guide will walk you through setting up and running a basic fine-tuning task.

	Requirements: Python >=3.10 and Pytorch >=2.1.1.

	```bash
	git clone https://github.com/OpenAccess-AI-Collective/axolotl
	cd axolotl

	pip3 install packaging ninja
	pip3 install -e '.[flash-attn,deepspeed]'
	```

	### Usage
	```bash
	# preprocess datasets - optional but recommended
	CUDA_VISIBLE_DEVICES="" python -m axolotl.cli.preprocess examples/openllama-3b/lora.yml

	# finetune lora
	accelerate launch -m axolotl.cli.train examples/openllama-3b/lora.yml

	# inference
	accelerate launch -m axolotl.cli.inference examples/openllama-3b/lora.yml \
	--lora_model_dir="./lora-out"

	# gradio
	accelerate launch -m axolotl.cli.inference examples/openllama-3b/lora.yml \
	--lora_model_dir="./lora-out" --gradio

	# remote yaml files - the yaml config can be hosted on a public URL
	# Note: the yaml config must directly link to the raw yaml
	accelerate launch -m axolotl.cli.train https://raw.githubusercontent.com/OpenAccess-AI-Collective/axolotl/main/examples/openllama-3b/lora.yml
	```

	## Advanced Setup

	### Environment

	#### Docker

	```bash
	docker run --gpus '"all"' --rm -it winglian/axolotl:main-latest
	```

	Or run on the current files for development:

	```sh
	docker compose up -d
	```

	>[!Tip]
	> If you want to debug axolotl or prefer to use Docker as your development environment, see the [debugging guide's section on Docker](docs/debugging.qmd#debugging-with-docker).

	<details>

	<summary>Docker advanced</summary>

	A more powerful Docker command to run would be this:

	```bash
	docker run --privileged --gpus '"all"' --shm-size 10g --rm -it --name axolotl --ipc=host --ulimit memlock=-1 --ulimit stack=67108864 --mount type=bind,src="${PWD}",target=/workspace/axolotl -v ${HOME}/.cache/huggingface:/root/.cache/huggingface winglian/axolotl:main-latest
	```

	It additionally:
	* Prevents memory issues when running e.g. deepspeed (e.g. you could hit SIGBUS/signal 7 error) through `--ipc` and `--ulimit` args.
	* Persists the downloaded HF data (models etc.) and your modifications to axolotl code through `--mount`/`-v` args.
	* The `--name` argument simply makes it easier to refer to the container in vscode (`Dev Containers: Attach to Running Container...`) or in your terminal.
	* The `--privileged` flag gives all capabilities to the container.
	* The `--shm-size 10g` argument increases the shared memory size. Use this if you see `exitcode: -7` errors using deepspeed.

	```
	More info: [mac.md](/docs/mac.qmd)

	#### Google Colab

	Please use this example [notebook](examples/colab-notebooks/colab-axolotl-example.ipynb).

	#### Launching on public clouds via SkyPilot
	To launch on GPU instances (both on-demand and spot instances) on 7+ clouds (GCP, AWS, Azure, OCI, and more), you can use [SkyPilot](https://skypilot.readthedocs.io/en/latest/index.html):

	```bash
	pip install "skypilot-nightly[gcp,aws,azure,oci,lambda,kubernetes,ibm,scp]" # choose your clouds
	sky check
	```

	Get the [example YAMLs](https://github.com/skypilot-org/skypilot/tree/master/llm/axolotl) of using Axolotl to finetune `mistralai/Mistral-7B-v0.1`:
	```
	git clone https://github.com/skypilot-org/skypilot.git
	cd skypilot/llm/axolotl
	```

	Use one command to launch:
	```bash
	# On-demand
	HF_TOKEN=xx sky launch axolotl.yaml --env HF_TOKEN

	# Managed spot (auto-recovery on preemption)
	HF_TOKEN=xx BUCKET=<unique-name> sky spot launch axolotl-spot.yaml --env HF_TOKEN --env BUCKET
	```

	#### Launching on public clouds via dstack
	To launch on GPU instance (both on-demand and spot instances) on public clouds (GCP, AWS, Azure, Lambda Labs, TensorDock, Vast.ai, and CUDO), you can use [dstack](https://dstack.ai/).

	Write a job description in YAML as below:

	```yaml
	# dstack.yaml
	type: task

	image: winglian/axolotl-cloud:main-20240429-py3.11-cu121-2.2.2

	env:
	- HUGGING_FACE_HUB_TOKEN
	- WANDB_API_KEY

	commands:
	- accelerate launch -m axolotl.cli.train config.yaml

	ports:
	- 6006

	resources:
	gpu:
	memory: 24GB..
	count: 2
	```

	then, simply run the job with `dstack run` command. Append `--spot` option if you want spot instance. `dstack run` command will show you the instance with cheapest price across multi cloud services:

	```bash
	pip install dstack
	HUGGING_FACE_HUB_TOKEN=xxx WANDB_API_KEY=xxx dstack run . -f dstack.yaml # --spot
	```

	For further and fine-grained use cases, please refer to the official [dstack documents](https://dstack.ai/docs/) and the detailed description of [axolotl example](https://github.com/dstackai/dstack/tree/master/examples/fine-tuning/axolotl) on the official repository.

	### Dataset

	Axolotl supports a variety of dataset formats. It is recommended to use a JSONL. The schema of the JSONL depends upon the task and the prompt template you wish to use. Instead of a JSONL, you can also use a HuggingFace dataset with columns for each JSONL field.

	See [these docs](https://openaccess-ai-collective.github.io/axolotl/docs/dataset-formats/) for more information on how to use different dataset formats.

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

	# huggingface repo with specific configuration/subset
	- 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
	- path: bigcode/commitpackft
	name:
	- ruby
	- python
	- typescript
	type: ... # unimplemented custom format

	# fastchat conversation
	# See 'conversation' options: https://github.com/lm-sys/FastChat/blob/main/fastchat/conversation.py
	- path: ...
	type: sharegpt
	conversation: chatml # default: vicuna_v1.1

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

	# dataset with splits, but no train split
	- path: knowrohit07/know_sql
	type: context_qa.load_v2
	train_on_split: validation

	# loading from s3 or gcs
	# s3 creds will be loaded from the system default and gcs only supports public access
	- path: s3://path_to_ds # Accepts folder with arrow/parquet or file path like above. Supports s3, gcs.
	...

	# Loading Data From a Public URL
	# - The file format is `json` (which includes `jsonl`) by default. For different formats, adjust the `ds_type` option accordingly.
	- path: https://some.url.com/yourdata.jsonl # The URL should be a direct link to the file you wish to load. URLs must use HTTPS protocol, not HTTP.
	ds_type: json # this is the default, see other options below.
	```

	- loading
	```yaml
	load_in_4bit: true
	load_in_8bit: true

	bf16: auto # require >=ampere, auto will detect if your GPU supports this and choose automatically.
	fp16: # leave empty to use fp16 when bf16 is 'auto'. set to false if you want to fallback to fp32
	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
	```

	#### All Config Options

	See [these docs](docs/config.qmd) for all config options.

	### Train

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

	> [!TIP]
	> You can also reference a config file that is hosted on a public URL, for example `accelerate launch -m axolotl.cli.train https://yourdomain.com/your_config.yml`

	#### Preprocess dataset

	You can optionally pre-tokenize dataset with the following before finetuning.
	This is recommended for large datasets.

	- Set `dataset_prepared_path:` to a local folder for saving and loading pre-tokenized dataset.
	- (Optional): Set `push_dataset_to_hub: hf_user/repo` to push it to Huggingface.
	- (Optional): Use `--debug` to see preprocessed examples.

	```bash
	python -m axolotl.cli.preprocess your_config.yml
	```

	#### Multi-GPU

	Below are the options available in axolotl for training with multiple GPUs. Note that DeepSpeed
	is the recommended multi-GPU option currently because FSDP may experience
	[loss instability](https://github.com/huggingface/transformers/issues/26498).

	##### 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.

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

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

	##### FSDP

	- 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
	```

	##### FSDP + QLoRA

	Axolotl supports training with FSDP and QLoRA, see [these docs](docs/fsdp_qlora.qmd) for more information.

	##### Weights & Biases Logging

	Make sure your `WANDB_API_KEY` environment variable is set (recommended) or you login to wandb with `wandb login`.

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

	##### Special Tokens

	It is important to have special tokens like delimiters, end-of-sequence, beginning-of-sequence in your tokenizer's vocabulary. This will help you avoid tokenization issues and help your model train better. You can do this in axolotl like this:

	```yml
	special_tokens:
	bos_token: "<s>"
	eos_token: "</s>"
	unk_token: "<unk>"
	tokens: # these are delimiters
	- "<\|im_start\|>"
	- "<\|im_end\|>"
	```

	When you include these tokens in your axolotl config, axolotl adds these tokens to the tokenizer's vocabulary.

	### Inference Playground

	Axolotl allows you to load your model in an interactive terminal playground for quick experimentation.
	The config file is the same config file used for training.

	Pass the appropriate flag to the inference command, depending upon what kind of model was trained:

	- 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
	```
	-- With gradio hosting
	```bash
	python -m axolotl.cli.inference examples/your_config.yml --gradio
	```

	Please use `--sample_packing False` if you have it on and receive the error similar to below:

	> RuntimeError: stack expects each tensor to be equal size, but got [1, 32, 1, 128] at entry 0 and [1, 32, 8, 128] at entry 1

	### Merge LORA to base

	The following command will merge your LORA adapater with your base model. You can optionally pass the argument `--lora_model_dir` to specify the directory where your LORA adapter was saved, otherwhise, this will be inferred from `output_dir` in your axolotl config file. The merged model is saved in the sub-directory `{lora_model_dir}/merged`.

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

	You may need to use the `gpu_memory_limit` and/or `lora_on_cpu` config options to avoid running out of memory. If you still run out of CUDA memory, you can try to merge in system RAM with

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

	although this will be very slow, and using the config options above are recommended instead.

	## Common Errors 🧰

	See also the [FAQ's](./docs/faq.qmd) and [debugging guide](docs/debugging.qmd).

	> 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`

	If it does not help, try running without deepspeed and without accelerate (replace "accelerate launch" with "python") in the command.

	Using adamw_bnb_8bit might also save you some memory.

	> `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.qmd) guide.


	### Tokenization Mismatch b/w Inference & Training

	For many formats, Axolotl constructs prompts by concatenating token ids _after_ tokenizing strings. The reason for concatenating token ids rather than operating on strings is to maintain precise accounting for attention masks.

	If you decode a prompt constructed by axolotl, you might see spaces between tokens (or lack thereof) that you do not expect, especially around delimiters and special tokens. When you are starting out with a new format, you should always do the following:

	1. Materialize some data using `python -m axolotl.cli.preprocess your_config.yml --debug`, and then decode the first few rows with your model's tokenizer.
	2. During inference, right before you pass a tensor of token ids to your model, decode these tokens back into a string.
	3. Make sure the inference string from #2 looks exactly like the data you fine tuned on from #1, including spaces and new lines. If they aren't the same, adjust your inference server accordingly.
	4. As an additional troubleshooting step, you can look at the token ids between 1 and 2 to make sure they are identical.

	Having misalignment between your prompts during training and inference can cause models to perform very poorly, so it is worth checking this. See [this blog post](https://hamel.dev/notes/llm/05_tokenizer_gotchas.html) for a concrete example.
