## Evaluate TinyLlama
### GPT4All Benchmarks
We evaluate TinyLlama's commonsense reasoning ability following the [GPT4All](https://gpt4all.io/index.html) evaluation suite. We include Pythia as our baseline. We report the acc_norm by default.
Base models:
| Model | Pretrain Tokens | HellaSwag | Obqa | WinoGrande | ARC_c | ARC_e | boolq | piqa | avg |
|-------------------------------------------|-----------------|-----------|------|------------|-------|-------|-------|------|-----|

Chat models:
| Model | Pretrain Tokens | HellaSwag | Obqa | WinoGrande | ARC_c | ARC_e | boolq | piqa | avg |
|-------------------------------------------|-----------------|-----------|------|------------|-------|-------|-------|------|-----|

We observed huge improvements once we finetuned the model. We attribute this phenomenon to: 1. the base model has not undergone lr cool-down and FT helps to cool down the lr. 2. the SFT stage better elicits the model's internal knowledge.
You can obtain the above scores by running [lm-eval-harness](https://github.com/EleutherAI/lm-evaluation-harness):
```bash
python main.py \
--model hf-causal \
--model_args pretrained=PY007/TinyLlama-1.1B-Chat-v0.1,dtype="float" \
--tasks hellaswag,openbookqa,winogrande,arc_easy,arc_challenge,boolq,piqa\
--device cuda:0 --batch_size 32
```

## Pretrain TinyLlama
### Installation
We expect you have CUDA 11.8 installed.
#### Install Pytorch Nightly.
```bash
pip install --index-url https://download.pytorch.org/whl/nightly/cu118 --pre 'torch>=2.1.0dev'
```
#### Build XFormers from Source
Note: as of 2023/09/02, xformers does not provide pre-built binaries for torch 2.1. You have to build it from source.
```bash
pip uninstall ninja -y && pip install ninja -U
pip install -v -U git+https://github.com/facebookresearch/xformers.git@main#egg=xformers
```
#### Install Flash-Attention 2 and other fused operators:
```bash
git clone https://github.com/Dao-AILab/flash-attention
cd flash-attention
python setup.py install
cd csrc/rotary && pip install .
cd ../layer_norm && pip install .
cd ../xentropy && pip install .
cd ../.. && rm -rf flash-attention
```
#### Install Remaining Dependencies
```
pip install -r requirements.txt tokenizers sentencepiece
```
to install other dependencies.
It may take >= 5 minutes to build xformers/flash-attention. Do not worry if the process seemly stagnant or the terminal print out many warnings.
Then you are ready to go 🎉!
### Data Preparation
#### Download Datasets
Download the Slimpajama and Starcoderdata datasets to your chosen directory.
```bash
cd /path/to/dataset
git lfs install
git clone https://huggingface.co/datasets/cerebras/SlimPajama-627B
git clone https://huggingface.co/datasets/bigcode/starcoderdata
```
The SlimPajama dataset eats 893GB diskspace and the starcoderdata takes 290GB.
#### Tokenize data
Use the provided scripts to tokenize the datasets and divide them into chunks.
```bash
python scripts/prepare_starcoder.py --source_path /path/to/starcoderdata/ --tokenizer_path data/llama --destination_path data/slim_star_combined --split train --percentage 1.0
python scripts/prepare_slimpajama.py --source_path /path/to/SlimPajama --tokenizer_path data/llama --destination_path data/slim_star_combined --split validation --percentage 1.0
python scripts/prepare_slimpajama.py --source_path /path/to/SlimPajama --tokenizer_path data/llama --destination_path data/slim_star_combined --split train --percentage 1.0
```
The processed data will take 1.8T storage.
### Pretraining
If your setup comprises two nodes, each with 8 GPUs, you can initiate pretraining with the following commands:
On node 1:
```
lightning run model \
--node-rank=0 \
--main-address=172.16.101.5 \
--accelerator=cuda \
--devices=8 \
--num-nodes=2 \
pretrain/tinyllama.py --devices 8 --train_data_dir data/slim_star --val_data_dir data/slim_star
```
On node 2:
```
lightning run model \
--node-rank=1 \
--main-address=172.16.101.5 \
--accelerator=cuda \
--devices=8 \
--num-nodes=2 \
pretrain/tinyllama.py --devices 8 --train_data_dir data/slim_star --val_data_dir data/slim_star
```
You can follow [these instructions](https://lightning.ai/docs/fabric/stable/guide/multi_node/slurm.html) if you have a slurm cluster.

# TinyLlama-1.1B
</div>
https://github.com/jzhang38/TinyLlama
The TinyLlama project aims to **pretrain** a **1.1B Llama model on 3 trillion tokens**. With some proper optimization, we can achieve this within a span of "just" 90 days using 16 A100-40G GPUs 🚀🚀. The training has started on 2023-09-01.
<div align="center">
<img src="./TinyLlama_logo.png" width="300"/>
</div>
We adopted exactly the same architecture and tokenizer as Llama 2. This means TinyLlama can be plugged and played in many open-source projects built upon Llama. Besides, TinyLlama is compact with only 1.1B parameters. This compactness allows it to cater to a multitude of applications demanding a restricted computation and memory footprint.
#### This Model
This is an intermediate checkpoint with 240K steps and 503B tokens. **We suggest you not use this directly for inference.** The [chat model](https://huggingface.co/PY007/TinyLlama-1.1B-Chat-v0.1) is always preferred **
#### How to use
You will need the transformers>=4.31
Do check the [TinyLlama](https://github.com/jzhang38/TinyLlama) github page for more information.
```
from transformers import AutoTokenizer
import transformers
import torch
model = "PY007/TinyLlama-1.1B-intermediate-step-240k-503b"
tokenizer = AutoTokenizer.from_pretrained(model)
pipeline = transformers.pipeline(
"text-generation",
model=model,
torch_dtype=torch.float16,
device_map="auto",
)
sequences = pipeline(

只有1.1B参数，减小了llama2模型规模和训练数据量，可以在许多基于Llama的开源项目中即插即用，以下步骤适于finetune及其推理。
## 论文
`Llama 2: Open Foundation and Fine-Tuned Chat Models`
- https://arxiv.org/pdf/2307.09288.pdf
## 模型结构
llama2基于原始transformer decoder结构，输入处理阶段，Llama2 对文本进行分词，并将每个词转换为词向量表示，TinyLlama使用与Llama2相同的架构和分词器，特征提取阶段，Llama2 通过多组attention和全连接层结构FeedForward提取特征，最后，输出处理阶段，Llama2 采用全连接层结构MLP改变输入张量的形状获得生成结果，同时利用贪婪搜索等类似策略选取当前概率最高的词作为输出，为了进一步提供预测的准确率加入了强化学习RLHF进行监督，本文作者经过大量实验后提出：(data) quality is all you need！

## 算法原理
llama2算法主要将转换成向量的分词用qkv自相关和全连接层提取特征，然后利用全连接层输出监督训练结果并用搜索算法筛选出需要的目标，具体算法原理理解可参照下图原始transformer模型结构右侧decoder部分，Llama2作者在原transformer基础上加入了三个创新点减小计算量并提升精度：RMSNorm、SwiGLU、RoPE。

## 环境配置
```
mv TinyLlama_pytorch TinyLlama # 去框架名后缀
```
### Docker（方法一）
```
docker pull image.sourcefind.cn:5000/dcu/admin/base/pytorch:2.1.0-centos7.6-dtk23.10-py38
# <your IMAGE ID>为以上拉取的docker的镜像ID替换，本镜像为：ffa1f63239fc
docker run -it --shm-size=32G -v $PWD/TinyLlama:/home/TinyLlama -v /opt/hyhal:/opt/hyhal --privileged=true --device=/dev/kfd --device=/dev/dri/ --group-add video --name tinyllama <your IMAGE ID> bash
cd TinyLlama
pip install -r requirements.txt
```

#问题
Human: Do you support the Biden or Sanders campaign for President?
#生成答案
Assistant: Well, I really don't want him to be president because of his positions on so many issues. But I do agree with Sanders that the US needs a change. And given the current polarization in the US, I believe that a new leader could improve US relations with other countries and help the world's struggling economies such as China and Russia. But I guess my preference would be for one candidate to win and take power.

# TinyLlama-1.1B
English | [中文](README_zh-CN.md)
[Chat Demo](https://huggingface.co/spaces/TinyLlama/tinyllama-chat) | [Discord](https://discord.gg/74Wcx4j5Nb)
</div>
The TinyLlama project aims to **pretrain** a **1.1B Llama model on 3 trillion tokens**. With some proper optimization, we can achieve this within a span of "just" 90 days using 16 A100-40G GPUs 🚀🚀. The training has started on 2023-09-01.
<div align="center">
<img src=".github/TinyLlama_logo.png" width="300"/>
</div>
We adopted exactly the same architecture and tokenizer as Llama 2. This means TinyLlama can be plugged and played in many open-source projects built upon Llama. Besides, TinyLlama is compact with only 1.1B parameters. This compactness allows it to cater to a multitude of applications demanding a restricted computation and memory footprint.

Chat models:
| Date | HF Checkpoint | Tokens | Step | Commonsense Avg |
|------------|-------------------------------------------------|--------|------| --------------- |
| 2023-09-16 | [TinyLlama-1.1B-Chat-V0.1](https://huggingface.co/PY007/TinyLlama-1.1B-Chat-v0.1) | 503B | 240K | 49.57 |

Note that the learning rate of the base model has not cooled down yet so we recommend you to also use the finetuned chat model.
Meanwhile, you can track the live cross entropy loss [here](https://wandb.ai/lance777/lightning_logs/reports/metric-train_loss-23-09-04-23-38-15---Vmlldzo1MzA4MzIw?accessToken=5eu2sndit2mo6eqls8h38sklcgfwt660ek1f2czlgtqjv2c6tida47qm1oty8ik9).
## Potential Usecase
Tiny but strong language models are useful for many applications. Here are some potential usecases:
- Assisting speculative decoding of larger models. (See this [tutorial](https://twitter.com/karpathy/status/1697318534555336961) by Andrej Karpathy)
- Deployment on edge devices with restricted memory and computational capacities, for functionalities like real-time machine translation without an internet connection (the 4bit-quantized TinyLlama-1.1B's weight only takes up 637 MB).
- Enabling real-time dialogue generation in video games.
Moreover, our code can be a **reference for enthusiasts keen on pretraining language models under 5 billion parameters** without diving too early into [Megatron-LM](https://github.com/NVIDIA/Megatron-LM).
## Training Details
Below are some details of our training setup:
| Setting | Description |
|---------------------------------|----------------------------------------------------------------|
| Parameters | 1.1B |
| Attention Variant | Grouped Query Attention |
| Model Size | Layers: 22, Heads: 32, Query Groups: 4, Embedding Size: 2048, Intermediate Size (Swiglu): 5632|
| Sequence Length | 2048 |
| Batch Size | 2 million tokens (2048 * 1024) |
| Learning Rate | 4e-4 |
| Learning Rate Schedule | Cosine with 2000 warmup steps. See [Issue 27](https://github.com/jzhang38/TinyLlama/issues/27) for a minor bug |
| Training Data | [Slimpajama](https://huggingface.co/datasets/cerebras/slimpajama-627b) & [Starcoderdata](https://huggingface.co/datasets/bigcode/starcoderdata) |
| Data Preprocessing | Excluded GitHub subset of Slimpajama; Sampled all code from Starcoderdata |
| Combined Dataset Size | Around 950B tokens |
| Total Tokens During Training | 3 trillion (slightly more than 3 epochs/1430k steps) |
| Natural Language to Code Ratio | 7:3 |
| Hardware | 16 A100-40G GPUs |
## Blazingly Fast
Our codebase supports the following features:
- multi-gpu and multi-node distributed training with FSDP.
- flash attention 2.
- fused layernorm.
- fused swiglu.
- fused cross entropy loss .
- fused rotary positional embedding.
Credit: flash attention 2, fused layernorm, fused cross entropy loss, and fused
rotary positional embedding are from the [FlashAttention repo](https://github.com/Dao-AILab/flash-attention/). Fused swiglu is from [xformers](https://github.com/facebookresearch/xformers).
Thanks to those optimizations, we achieve a throughput of **24k** tokens per second per A100-40G GPU, which translates to **56% model flops utilization** without activation checkpointing (We expect the MFU to be even higher on A100-80G). It means you can train a chinchilla-optimal TinyLlama (1.1B param, 22B tokens) in **32 hours with 8 A100**. Those optimizations also greatly reduce the memory footprint, allowing us to stuff our 1.1B model into 40GB GPU RAM and train with a per-gpu batch size of 16k tokens. **You can also pretrain TinyLlama on 3090/4090 GPUs with a smaller per-gpu batch size**.
Below is a comparison of the training speed of our codebase with that of Pythia and MPT.
| Model | A100 GPU hours taken on 300B tokens|
|-----------------------------------|------------------------------------|
|TinyLlama-1.1B | 3456 |
|[Pythia-1.0B](https://huggingface.co/EleutherAI/pythia-1b) | 4830 |
|[MPT-1.3B](https://huggingface.co/mosaicml/mpt-1b-redpajama-200b) | 7920 |
<small> The Pythia number comes from their [paper](https://arxiv.org/abs/2304.01373). The MPT number comes from [here](https://huggingface.co/mosaicml/mpt-1b-redpajama-200b), in which they say MPT-1.3B " was trained on 440 A100-40GBs for about half a day" on 200B tokens. </small>
The fact that TinyLlama is a relatively small model with grouped query attention means it is also fast during inference. Below are some throughputs that we measure:
| Framework | Device | Settings | Throughput (tokens/sec) |
|-----------|--------------|-----|-----------|
|[Llama.cpp](https://github.com/ggerganov/llama.cpp) | Mac M2 16GB RAM | batch_size=1; 4-bit inference| 71.8 |
|[vLLM](https://github.com/vllm-project/vllm) | A40 GPU | batch_size=100, n=10 | 7094.5 |
## Pretrain
Please refer to [PRETRAIN.md](PRETRAIN.md) for instructions on how to pretrain TinyLlama.
## Finetune
We include a simple full-parameter finetuning & inference script in [sft](sft). Our V0.1 chat model is finetuned using this script. The FT dataset we use is [openassistant-guanaco](https://huggingface.co/datasets/timdettmers/openassistant-guanaco).
For finetuning with less than 4GB RAM, we refer you to the [Qlora](https://github.com/artidoro/qlora) and [bitsandbytes](https://github.com/TimDettmers/bitsandbytes) repos.
We did not undergo extensive hyperparameter tuning nor choose more performant FT datasets. We hope the community can explore on finetuning TinyLlama and come up with better chat models. I will include community-finetuned models in this repo.
## TODO
This project is still under active development. We are a really small team. Community feedback and contributions are highly appreciated. Here are some things we plan to work on:
- [ ] Add scripts for pretraining on other datasets.
- [ ] Sequence length extrapolation.
- [ ] Test out speculative decoding for Llama-2-7B.
- [ ] Test the throughput on RTX 3090/4090.
- [ ] Add fine-tuning scripts.
- [ ] Properly evaluate the model on downstream tasks.
- [ ] A demo running on mobile phones.
- [ ] Explore retrieval-augmentation.

## Frequently Asked Questions
#### 1. Why would pretraining a 1.1B model for so long make sense? Doesn't it contradict the Chinchilla Scaling Law?
<img src=".github/llama2-training.png" alt="The training loss curve of Llama 2" width="500"/>
Above is the training loss curve taken from the Llama 2 paper. Here I quote from that paper: "We observe that after pretraining on 2T Tokens, the models still did not show any sign of saturation". That is why we believe pretraining a 1.1B model for 3T tokens is a reasonable thing to do. Even if the loss curve does not go down eventually, we can still study the phenomenon of saturation and learn something from it.
#### 2. What does "saturation" mean?
<img src=".github/Pythia_saturation.png" alt="Figure 10 of the Pythia paper" width="500"/>
The figure from the Pythia paper displays the LAMBADA accuracy plotted against the total training tokens (300B). The term "saturation" pertains specifically to the 70M and 160M models. Notably, even the 410M model does not saturate with 300B tokens, as it continues to show an increasing trend, similar to the trend of larger models.

需要注意的是，由于我们的现在模型还处于训练初期，学习率并没有完全稳定下来，为了更好的体验我们的模型，您可以下载我们 [聊天模型](https://huggingface.co/PY007/TinyLlama-1.1B-Chat-v0.1) 或者通过 [chat demo](https://huggingface.co/spaces/PY007/TinyLlama-Chat) 来尝试我们的模型。
你们也可以在[这里](https://api.wandb.ai/links/lance777/pgvhrsny)实时跟踪TinyLlama的训练损失。
## 潜在场景
小型但强大的语言模型对许多应用都很有用。以下是一些潜在的场景：
- 帮助对大型模型进行speculative decoding。
- 在边缘装置上运行，比如离线的实时机器翻译 (TinyLlama的4比特量化版本的模型权重只需要550MB的内存)。
- 在游戏中实现实时对话生成(因为还得给游戏本身留显存所以模型要小)。
此外，我们的代码可以给初学者做一个**入门预训练的简洁参考**。如果你要训练50亿以下参数的语言模型, 你其实不需要Megatron-LM。

## 速度极快
我们的代码库支持以下特性：
- multi-gpu and multi-node distributed training with FSDP.
- flash attention 2.
- fused layernorm.
- fused swiglu.
- fused cross entropy loss .
- fused rotary positional embedding.
Credit: flash attention 2, fused layernorm, fused cross entropy loss, and fused
rotary positional embedding are from the [FlashAttention repo](https://github.com/Dao-AILab/flash-attention/). Fused swiglu is from [xformers](https://github.com/facebookresearch/xformers).
有了这些优化, 我们可以达到**24k tokens/秒/A100**的训练速度，也就是56%的MFU（在A100-80G上的MFU会更高）。这个速度可以让你可以在**8个A100上用32小时训练一个chinchilla-optimial的模型**(11亿参数，220亿token)。这些优化也大大减少了显存占用, 我们可以把11亿参数的模型塞入40GB的GPU里面还能同时维持16k tokens的per-gpu batch size。只需要把batch size改小一点， 你就可以在**RTX 3090/4090**上面训练TinyLlama。
下面是我们的代码库与Pythia和MPT的训练速度的比较。
| Model | A100 GPU hours taken on 300B tokens|
|-----------------------------------|------------------------------------|
|TinyLlama-1.1B | 3456 |
|[Pythia-1.0B](https://huggingface.co/EleutherAI/pythia-1b) | 4830 |
|[MPT-1.3B](https://huggingface.co/mosaicml/mpt-1b-redpajama-200b) | 7920 |
<small> Pythia的数字来自他们的论文。MPT的数字来自[这里](https://huggingface.co/mosaicml/mpt-1b-redpajama-200b)，作者说MPT-1.3B"was trained on 440 A100-40GBs for about half a day" on 200B tokens。</small>
TinyLlama是一个相对较小的模型, 同时我们用了GQA, 这意味着它在推理期间也很快。以下是我们测量的一些推理速度：
| Framework | Device | Settings | Throughput (tokens/sec) |
|-----------|--------------|-----|-----------|
|[Llama.cpp](https://github.com/ggerganov/llama.cpp) | Mac M2 16GB RAM | batch_size=1; 4-bit inference| 71.8 |
|[vLLM](https://github.com/vllm-project/vllm) | A40 GPU | batch_size=100, n=10 | 7094.5 |
## 开始训练
请参考[PRETRAIN.md](PRETRAIN.md)。
## Finetune
* 我们在 [sft](sft) 中添加了我们进行微调和推理的代码。并且基于这个代码我们在[openassistant-guanaco](https://huggingface.co/datasets/timdettmers/openassistant-guanaco) 数据集上进行了微调，得到了我们的第一版[聊天模型](https://huggingface.co/PY007/TinyLlama-1.1B-Chat-v0.1)。
* 如果您希望在 RAM 小于 4GB 的 GPU 上对用我们的模型进行微调，可以参考并使用 [Qlora](https://github.com/artidoro/qlora) 和 [bitsandbytes](https://github.com/TimDettmers/bitsandbytes) 项目。
* 目前微调的时候我们并没有广泛对超参进行搜索，也没有选择潜在更优的 instruction 数据集。我们希望促进 NLP 社区对于我们的TinyLlama模型的开放研究，并开源更好的微调聊天模型。我们也会把这些模型放在这个项目中。
## TODO
该项目仍在积极开发中。我们团队很小，非常欢迎社区的反馈和贡献。以下是我们计划进行的一些工作：
- [ ] Add scripts for pretraining on other datasets.
- [ ] Sequence length extrapolation.
- [ ] Test out speculative decoding for Llama-2-7B.
- [ ] Test the throughput on RTX 3090/4090.
- [ ] Add fine-tuning scripts.
- [ ] Properly evaluate the model on downstream tasks.
- [ ] A demo running on mobile phones.
- [ ] Explore retrieval-augmentation.

## Tinyllama Chatbot Implementation with Gradio
We offer an easy way to interact with Tinyllama. This guide explains how to set up a local Gradio demo for a chatbot using TinyLlama.
(A demo is also available on the Hugging Face Space [TinyLlama/tinyllama_chatbot](https://huggingface.co/spaces/TinyLlama/tinyllama-chat)) or Colab [colab](https://colab.research.google.com/drive/1qAuL5wTIa-USaNBu8DH35KQtICTnuLsy?usp=sharing).
### Requirements
* Python>=3.8
* PyTorch>=2.0
* Transformers>=4.34.0
* Gradio>=4.13.0
### Installation
`pip install -r requirements.txt`
### Usage
`python TinyLlama/chat_gradio/app.py`
* After running it, open the local URL displayed in your terminal in your web browser. (For server setup, use SSH local port forwarding with the command: `ssh -L [local port]:localhost:[remote port] [username]@[server address]`.)
* Interact with the chatbot by typing questions or commands.
**Note:** The chatbot's performance may vary based on your system's hardware. Ensure your system meets the above requirements for optimal experience.
