## Quickstart
### 1. Install package
First, install the airllm pip package.
```bash
pip install airllm
```
### 2. Inference
Then, initialize AirLLMLlama2, pass in the huggingface repo ID of the model being used, or the local path, and inference can be performed similar to a regular transformer model.
(*You can also specify the path to save the splitted layered model through **layer_shards_saving_path** when init AirLLMLlama2.*
```python
from airllm import AutoModel
MAX_LENGTH = 128
# could use hugging face model repo id:
model = AutoModel.from_pretrained("garage-bAInd/Platypus2-70B-instruct")
# or use model's local path...
#model = AutoModel.from_pretrained("/home/ubuntu/.cache/huggingface/hub/models--garage-bAInd--Platypus2-70B-instruct/snapshots/b585e74bcaae02e52665d9ac6d23f4d0dbc81a0f")
input_text = [
'What is the capital of United States?',
#'I like',
]
input_tokens = model.tokenizer(input_text,
return_tensors="pt",
return_attention_mask=False,
truncation=True,
max_length=MAX_LENGTH,
padding=False)
generation_output = model.generate(
input_tokens['input_ids'].cuda(),
max_new_tokens=20,
use_cache=True,
return_dict_in_generate=True)
output = model.tokenizer.decode(generation_output.sequences[0])
print(output)
```
Note: During inference, the original model will first be decomposed and saved layer-wise. Please ensure there is sufficient disk space in the huggingface cache directory.
## Model Compression - 3x Inference Speed Up!
We just added model compression based on block-wise quantization-based model compression. Which can further **speed up the inference speed** for up to **3x** , with **almost ignorable accuracy loss!** (see more performance evaluation and why we use block-wise quantization in [this paper](https://arxiv.org/abs/2212.09720))
#### How to enable model compression speed up:
* Step 1. make sure you have [bitsandbytes](https://github.com/TimDettmers/bitsandbytes) installed by `pip install -U bitsandbytes `
* Step 2. make sure airllm verion later than 2.0.0: `pip install -U airllm`
* Step 3. when initialize the model, passing the argument compression ('4bit' or '8bit'):
```python
model = AutoModel.from_pretrained("garage-bAInd/Platypus2-70B-instruct",
compression='4bit' # specify '8bit' for 8-bit block-wise quantization
)
```
#### What are the differences between model compression and quantization?
Quantization normally needs to quantize both weights and activations to really speed things up. Which makes it harder to maintain accuracy and avoid the impact of outliers in all kinds of inputs.
While in our case the bottleneck is mainly at the disk loading, we only need to make the model loading size smaller. So, we get to only quantize the weights' part, which is easier to ensure the accuracy.
## Configurations
When initialize the model, we support the following configurations:
* **compression**: supported options: 4bit, 8bit for 4-bit or 8-bit block-wise quantization, or by default None for no compression
* **profiling_mode**: supported options: True to output time consumptions or by default False
* **layer_shards_saving_path**: optionally another path to save the splitted model
* **hf_token**: huggingface token can be provided here if downloading gated models like: *meta-llama/Llama-2-7b-hf*
* **prefetching**: prefetching to overlap the model loading and compute. By default, turned on. For now, only AirLLMLlama2 supports this.
* **delete_original**: if you don't have too much disk space, you can set delete_original to true to delete the original downloaded hugging face model, only keep the transformed one to save half of the disk space.
## MacOS
Just install airllm and run the code the same as on linux. See more in [Quick Start](#quickstart).
* make sure you installed [mlx](https://github.com/ml-explore/mlx?tab=readme-ov-file#installation) and torch
* you probably need to install python native see more [here](https://stackoverflow.com/a/65432861/21230266)
* only [Apple silicon](https://support.apple.com/en-us/HT211814) is supported

## FAQ
### 1. MetadataIncompleteBuffer
safetensors_rust.SafetensorError: Error while deserializing header: MetadataIncompleteBuffer
If you run into this error, most possible cause is you run out of disk space. The process of splitting model is very disk-consuming. See [this](https://huggingface.co/TheBloke/guanaco-65B-GPTQ/discussions/12). You may need to extend your disk space, clear huggingface [.cache](https://huggingface.co/docs/datasets/cache) and rerun.
### 2. ValueError: max() arg is an empty sequence
Most likely you are loading QWen or ChatGLM model with Llama2 class. Try the following:
For QWen model:
```python
from airllm import AutoModel #<----- instead of AirLLMLlama2
AutoModel.from_pretrained(...)
```
For ChatGLM model:
```python
from airllm import AutoModel #<----- instead of AirLLMLlama2
AutoModel.from_pretrained(...)
```
### 3. 401 Client Error....Repo model ... is gated.
Some models are gated models, needs huggingface api token. You can provide hf_token:
```python
model = AutoModel.from_pretrained("meta-llama/Llama-2-7b-hf", #hf_token='HF_API_TOKEN')
```
### 4. ValueError: Asking to pad but the tokenizer does not have a padding token.
Some model's tokenizer doesn't have padding token, so you can set a padding token or simply turn the padding config off:
```python
input_tokens = model.tokenizer(input_text,
return_tensors="pt",
return_attention_mask=False,
truncation=True,
max_length=MAX_LENGTH,
padding=False #<----------- turn off padding
)
```

AIコミュニティは常に非常にオープンです。今日のAIの発展は、多くの重要なオープンソースの取り組み、共有された論文、オープンソースのコードやデータなしでは実現できなかったでしょう。私たちは、AIの未来も確実にオープンであると信じています。この取り組みがオープンソースコミュニティに貢献できることを願っています。
**なぜ33Bモデルが重要なのか？そしてなぜQLoRAがゲームチェンジャーかもしれないのか？**
以前は、ほとんどのオープンソースのファインチューニング可能なモデルは比較的小さく、7Bまたは13Bのパラメータを持っていました。これらのモデルは、ファインチューニングを通じていくつかの簡単なチャットボット評価データセットでまともなパフォーマンスを達成できましたが、その限られたサイズのため、言語モデル内のコア推論能力は依然として比較的弱いままでした。これが、多くの小規模モデルが実際のアプリケーションでおもちゃのように見える理由です。この[研究](https://yaofu.notion.site/Towards-Complex-Reasoning-the-Polaris-of-Large-Language-Models-c2b4a51355b44764975f88e6a42d4e75)で主張されているように、チャットボット評価データセットは比較的簡単であり、モデルの能力を真にテストする複雑な論理推論や数学の問題に関しては、小規模モデルと大規模モデルの間には大きなギャップがあります。
したがって、QLoRAの研究は非常に重要であり、ゲームチェンジャーになる可能性があると信じています。QLoRAの最適化方法を通じて、初めて33Bパラメータのモデルをより民主的でコスト効果の高い方法でファインチューニングし、普及させることができます。QLoRA 33Bモデルは、大規模モデルのより強力な推論能力を活用し、同時にプロプライエタリなビジネスドメインデータでファインチューニングおよびトレーニングを行うことで、大規模言語モデルの制御を強化することが可能になります。

## 🚀トレーニング
#### バックボーンモデル
Animaモデルは、QLoRAの[33B guanaco](https://huggingface.co/timdettmers/guanaco-33b)に基づいてトレーニングされています。1つのH100 GPUで10000ステップのファインチューニングが行われました。
* **理由**：この作業は主にQLoRAトレーニング方法の有効性を検証するためのものであり、QLoRAに基づいてGuanaco 33Bモデルをファインチューニングすることを選択しました。これは、モデルの日本語能力を強化することのみを目的としています。ベースモデルの基本的な論理推論および知識能力がすでに十分であると仮定しています。
#### トレーニングデータセット
主に[Chinese-Vicuna](https://github.com/Facico/Chinese-Vicuna)プロジェクトによってまとめられた日本語トレーニングデータセット[guanaco_belle_merge_v1.0](https://huggingface.co/datasets/Chinese-Vicuna/guanaco_belle_merge_v1.0)を使用してファインチューニングトレーニングを行います。
* **理由**：
[QLoRA](https://arxiv.org/abs/2305.14314)の結論に従って、QLoRAファインチューニングでは、トレーニングサンプルの数が多ければ多いほど良いわけではありません。10000ステップはROIが比較的良いサイズです。したがって、10000ステップ以上のデータセットを選択したいと考えています。[Belle 10M](https://github.com/LianjiaTech/BELLE/blob/main/data/10M)データセットは大きすぎるように思え、データの質が不明です。時間が限られているため、まずguanaco_belle_merge_v1.0を選択します。後で、より多くのデータセットとデータ品質フィルタリングの効果をより体系的にテストします。
* **感謝**：[Chinese-Vicuna](https://github.com/Facico/Chinese-Vicuna)、[Belle](https://github.com/LianjiaTech/BELLE)、[GuanacoDataset](https://huggingface.co/datasets/JosephusCheung/GuanacoDataset)のすべてのオープンデータセットへの貢献に感謝します。
#### ハイパーパラメータ
コストの考慮から、あまり多くのグリッドサーチを行わず、[QLoRA paper](https://arxiv.org/abs/2305.14314)の包括的なハイパーパラメータグリッドサーチ実験の結論が私たちの場合にも適用されると仮定しています：
* バッチサイズ: 16 ([QLoRA](https://arxiv.org/abs/2305.14314) Appendix B.4およびTable 9)
* 最大ステップ数: 10000 ([QLoRA](https://arxiv.org/abs/2305.14314) Appendix B.4およびTable 9)、より大きなデータセットでの追加ステップが実験中であり、新しい発見を報告し続けます。
* 学習率: 1e-4 ([QLoRA](https://arxiv.org/abs/2305.14314) Appendix B.4およびTable 9)
* LoRA r=64, alpha=16 ([QLoRA](https://arxiv.org/abs/2305.14314) Appendix B.2)
* source_max_len=512, target_max_len=512、トレーニングデータセットのほとんどの情報が切り捨てられずに完全に保持されることが重要です。この[スクリプト](https://github.com/lyogavin/Anima/blob/main/scripts/test_cn_dataset_lenghts.py)を使用してトークン長の分布を確認しました。結論として、512が良い選択であるようです。
#### トレーニングの再現方法
1. Animaモデルのトレーニングを再現する：Anima 33Bモデルは、以下の手順で完全に再現できます（1x80GB H100のシングルGPU環境または2xA100 40GBのマルチGPU環境でテスト済み）：
```bash
# 1. 依存関係をインストール
pip install -r requirements.txt
# 2.
cd training
./run_Amina_training.sh
```
2. Animaに基づいて他のモデルをファインチューニングする：
```bash
# 1. 依存関係をインストール
pip install -r requirements.txt
# 2.
cd training
./run_finetune_raining_based_on_Anima.sh
```
注：run_finetune_raining_based_on_Anima.shの--datasetおよび--dataset_format引数を変更して、データセットを指すようにしてください。
#### マルチGPUトレーニング
Hugging Face Accelerateのおかげで、マルチGPUトレーニングがすぐにサポートされます。
2xA100 40GBでテストしましたが、上記のスクリプトはシームレスに動作します。
## 📊評価🏆
#### Eloレーティングトーナメント
| モデル | Elo | ランク |
|-------------------|---------|------|
| ChatGPT-3.5 turbo | 1341.98 | 1 |
| **Anima 33B** | **1096.69** | **2** |
| Belle | 937.71 | 3 |
| Chinese Vicuna | 623.62 | 4 |
#### 評価方法論
* **評価データセット**：[Belle Paper](https://github.com/LianjiaTech/BELLE/blob/main/docs/Towards%20Better%20Instruction%20Following%20Language%20Models%20for%20Chinese.pdf)で議論されているように、評価セット内の異なるタイプの分布は評価結果に大きな影響を与えます。最終結果は、データセット内の異なるドメイン間の比率の反映です。したがって、英語のチャットボットモデル研究で広く認識されている[Vicunaベンチマーク](https://lmsys.org/blog/2023-03-30-vicuna/)を選択しました。日本語を評価するために、GPT4を使用して質問を翻訳しました。
* **評価アプローチ**：コストをバランスさせるために、主にGPT4を使用して評価を行います。[QLoRA](https://arxiv.org/abs/2305.14314)で主張されているように、純粋なGPT4スコアリングモデルの比較には大きなランダムな変動があります。これは私たちの観察と一致しています。したがって、[QLoRA](https://arxiv.org/abs/2305.14314)で推奨され、現在広く使用されているEloレーティングトーナメント評価方法を採用しました。
* **ハイパーパラメータの選択**：コストの考慮から、次のように選択しました：300ラウンドのランダム評価、モデルの順序をランダムに選択して順序の影響を相殺し、ランダムシードを42に設定します。Eloレーティングの実装コードおよび他のハイパーパラメータは[VicunaのEloコード](https://raw.githubusercontent.com/lm-sys/FastChat/833d65032a715240a3978f4a8f08e7a496c83cb1/fastchat/serve/monitor/elo_analysis.py)に従います：K=32、初期レーティング=1000。

#### 結論
現代のLLMモデルの最も重要な能力は、その論理推論能力と知識をエンコードする能力です。したがって、モデルの規模は重要な要素となる可能性があります。QLoRAメソッドを通じて、十分に低コストで与えられたハードウェア条件に対して最大のモデルをファインチューニングおよび最適化し、最良の結果を達成できます。
Animaモデルは、トレーニングデータの質を深く最適化することなく、わずか10000ステップのトレーニングで日本語モデルとして最適なパフォーマンスを達成しました。

## ✍️私たちは誰ですか？
この作業は[Aiwrite Technology](https://aicompose.cn/about) <img src="https://static.aicompose.cn/static/logo/aiwrite_logo.png" width="99"/>から来ています。私たちのチームはシリコンバレー出身で、中国とアメリカの企業での多くの年の最前線のAIの仕事の経験があります。
私たちは、最新のAGIおよびLLM技術を使用して、コンテンツ作成のための次世代のコンテンツ作成ツールを提供することに取り組んでいます。
**私たちは信じています**：生成AIの時代において、「書く」ことは簡単になるのではなく、より難しくなります。これは、AIが優れたコンテンツクリエーターと平均的なクリエーターの間のギャップをますます平坦にしているためです。誰でも簡単にChatGPTを使ってコピーを作成することができます。
コンテンツクリエーターにコピーを「書く」ツールを提供するだけでは不十分です。コンテンツクリエーターが必要なのは「書く」ことではなく、「ヒットコンテンツを作成する」ことです。これは、「ヒットコンテンツ」のトレンドと、ユーザーの急速に変化する興味や嗜好に対する鋭い洞察を組み合わせる必要があります。私たちは、クリエーターが効率的にヒットコンテンツを作成できるAIを提供することを目指しています。
私たちは、中国のソーシャルメディアデータを大量に蓄積し、ヒットコンテンツの変動トレンドに関する豊富なリアルタイムデータを蓄積しています。ヒットコンテンツデータと最新のLLM AI技術を組み合わせることで、アルゴリズム配信の時代において、コンテンツクリエーターに真に効果的な競争優位性を提供します。

## Quickstart
### 1. Install package
First, install the airllm pip package.
```bash
pip install airllm
```
### 2. Inference
Then, initialize AirLLMLlama2, pass in the huggingface repo ID of the model being used, or the local path, and inference can be performed similar to a regular transformer model.
(*You can also specify the path to save the splitted layered model through **layer_shards_saving_path** when init AirLLMLlama2.*
```python
from airllm import AutoModel
MAX_LENGTH = 128
# could use hugging face model repo id:
model = AutoModel.from_pretrained("garage-bAInd/Platypus2-70B-instruct")
# or use model's local path...
#model = AutoModel.from_pretrained("/home/ubuntu/.cache/huggingface/hub/models--garage-bAInd--Platypus2-70B-instruct/snapshots/b585e74bcaae02e52665d9ac6d23f4d0dbc81a0f")
input_text = [
'What is the capital of United States?',
#'I like',
]
input_tokens = model.tokenizer(input_text,
return_tensors="pt",
return_attention_mask=False,
truncation=True,
max_length=MAX_LENGTH,
padding=False)
generation_output = model.generate(
input_tokens['input_ids'].cuda(),
max_new_tokens=20,
use_cache=True,
return_dict_in_generate=True)
output = model.tokenizer.decode(generation_output.sequences[0])
print(output)
```
Note: During inference, the original model will first be decomposed and saved layer-wise. Please ensure there is sufficient disk space in the huggingface cache directory.
## Model Compression - 3x Inference Speed Up!
We just added model compression based on block-wise quantization-based model compression. Which can further **speed up the inference speed** for up to **3x** , with **almost ignorable accuracy loss!** (see more performance evaluation and why we use block-wise quantization in [this paper](https://arxiv.org/abs/2212.09720))
#### How to enable model compression speed up:
* Step 1. make sure you have [bitsandbytes](https://github.com/TimDettmers/bitsandbytes) installed by `pip install -U bitsandbytes `
* Step 2. make sure airllm verion later than 2.0.0: `pip install -U airllm`
* Step 3. when initialize the model, passing the argument compression ('4bit' or '8bit'):
```python
model = AutoModel.from_pretrained("garage-bAInd/Platypus2-70B-instruct",
compression='4bit' # specify '8bit' for 8-bit block-wise quantization
)
```
#### What are the differences between model compression and quantization?
Quantization normally needs to quantize both weights and activations to really speed things up. Which makes it harder to maintain accuracy and avoid the impact of outliers in all kinds of inputs.
While in our case the bottleneck is mainly at the disk loading, we only need to make the model loading size smaller. So, we get to only quantize the weights' part, which is easier to ensure the accuracy.
## Configurations
When initialize the model, we support the following configurations:
* **compression**: supported options: 4bit, 8bit for 4-bit or 8-bit block-wise quantization, or by default None for no compression
* **profiling_mode**: supported options: True to output time consumptions or by default False
* **layer_shards_saving_path**: optionally another path to save the splitted model
* **hf_token**: huggingface token can be provided here if downloading gated models like: *meta-llama/Llama-2-7b-hf*
* **prefetching**: prefetching to overlap the model loading and compute. By default, turned on. For now, only AirLLMLlama2 supports this.
* **delete_original**: if you don't have too much disk space, you can set delete_original to true to delete the original downloaded hugging face model, only keep the transformed one to save half of the disk space.
## MacOS
Just install airllm and run the code the same as on linux. See more in [Quick Start](#quickstart).
* make sure you installed [mlx](https://github.com/ml-explore/mlx?tab=readme-ov-file#installation) and torch
* you probabaly need to install python native see more [here](https://stackoverflow.com/a/65432861/21230266)
* only [Apple silicon](https://support.apple.com/en-us/HT211814) is supported

## FAQ
### 1. MetadataIncompleteBuffer
safetensors_rust.SafetensorError: Error while deserializing header: MetadataIncompleteBuffer
If you run into this error, most possible cause is you run out of disk space. The process of splitting model is very disk-consuming. See [this](https://huggingface.co/TheBloke/guanaco-65B-GPTQ/discussions/12). You may need to extend your disk space, clear huggingface [.cache](https://huggingface.co/docs/datasets/cache) and rerun.
### 2. ValueError: max() arg is an empty sequence
Most likely you are loading QWen or ChatGLM model with Llama2 class. Try the following:
For QWen model:
```python
from airllm import AutoModel #<----- instead of AirLLMLlama2
AutoModel.from_pretrained(...)
```
For ChatGLM model:
```python
from airllm import AutoModel #<----- instead of AirLLMLlama2
AutoModel.from_pretrained(...)
```
### 3. 401 Client Error....Repo model ... is gated.
Some models are gated models, needs huggingface api token. You can provide hf_token:
```python
model = AutoModel.from_pretrained("meta-llama/Llama-2-7b-hf", #hf_token='HF_API_TOKEN')
```
### 4. ValueError: Asking to pad but the tokenizer does not have a padding token.
Some model's tokenizer doesn't have padding token, so you can set a padding token or simply turn the padding config off:
```python
input_tokens = model.tokenizer(input_text,
return_tensors="pt",
return_attention_mask=False,
truncation=True,
max_length=MAX_LENGTH,
padding=False #<----------- turn off padding
)
```
