**通义千问-1.8B(Qwen-1.8B)**是阿里云研发的通义千问大模型系列的18亿参数规模的模型。Qwen-1.8B是基于Transformer的大语言模型, 在超大规模的预训练数据上进行训练得到。预训练数据类型多样,覆盖广泛,包括大量网络文本、专业书籍、代码等。同时,在Qwen-1.8B的基础上,我们使用对齐机制打造了基于大语言模型的AI助手Qwen-1.8B-Chat。本仓库为Qwen-1.8B-Chat的Int4量化模型的仓库。
通义千问-1.8B(Qwen-1.8B)主要有以下特点:
如果您想了解更多关于通义千问1.8B开源模型的细节,我们建议您参阅GitHub代码库。
Qwen-1.8B is the 1.8B-parameter version of the large language model series, Qwen (abbr. Tongyi Qianwen), proposed by Aibaba Cloud. Qwen-1.8B is a Transformer-based large language model, which is pretrained on a large volume of data, including web texts, books, codes, etc. Additionally, based on the pretrained Qwen-1.8B, we release Qwen-1.8B-Chat, a large-model-based AI assistant, which is trained with alignment techniques. This repository is the one for Qwen-1.8B-Chat-int4.
The features of Qwen-1.8B include:
For more details about the open-source model of Qwen-1.8B-chat int4, please refer to the GitHub code repository.
<br>运行Qwen-1.8B-Chat-Int4,请确保满足上述要求,再执行以下pip命令安装依赖库。如安装auto-gptq遇到问题,我们建议您到官方repo搜索合适的预编译wheel。
To run Qwen-1.8B-Chat-Int4, please make sure you meet the above requirements, and then execute the following pip commands to install the dependent libraries. If you meet problems installing auto-gptq, we advise you to check out the official repo to find a pre-build wheel.
pip install transformers==4.32.0 accelerate tiktoken einops scipy transformers_stream_generator==0.0.4 peft deepspeed
pip install auto-gptq optimum
另外,推荐安装flash-attention库(当前已支持flash attention 2),以实现更高的效率和更低的显存占用。
In addition, it is recommended to install the flash-attention library (we support flash attention 2 now.) for higher efficiency and lower memory usage.
git clone https://github.com/Dao-AILab/flash-attention
cd flash-attention && pip install .
# 下方安装可选,安装可能比较缓慢。
# pip install csrc/layer_norm
# pip install csrc/rotary
<br>
下面我们展示了一个使用Qwen-1.8B-Chat-Int4模型,进行多轮对话交互的样例:
We show an example of multi-turn interaction with Qwen-1.8B-Chat-Int4 in the following code:
from modelscope import AutoTokenizer, AutoModelForCausalLM, snapshot_download
tokenizer = AutoTokenizer.from_pretrained("qwen/Qwen-1_8B-Chat-Int4", revision='master', trust_remote_code=True)
model = AutoModelForCausalLM.from_pretrained(
"qwen/Qwen-1_8B-Chat-Int4", revision='master',
device_map="auto",
trust_remote_code=True
).eval()
response, history = model.chat(tokenizer, "你好", history=None)
print(response)
# 你好!很高兴为你提供帮助。
# Qwen-1.8B-Chat现在可以通过调整系统指令(System Prompt),实现角色扮演,语言风格迁移,任务设定,行为设定等能力。
# Qwen-1.8B-Chat can realize roly playing, language style transfer, task setting, and behavior setting by system prompt.
response, _ = model.chat(tokenizer, "你好呀", history=None, system="请用二次元可爱语气和我说话")
print(response)
# 你好啊!我是一只可爱的二次元猫咪哦,不知道你有什么问题需要我帮忙解答吗?
response, _ = model.chat(tokenizer, "My colleague works diligently", history=None, system="You will write beautiful compliments according to needs")
print(response)
# Your colleague is an outstanding worker! Their dedication and hard work are truly inspiring. They always go above and beyond to ensure that
# their tasks are completed on time and to the highest standard. I am lucky to have them as a colleague, and I know I can count on them to handle any challenge that comes their way.
关于更多的使用说明,请参考我们的GitHub repo获取更多信息。
For more information, please refer to our GitHub repo for more information.
注:作为术语的“tokenization”在中文中尚无共识的概念对应,本文档采用英文表达以利说明。
基于tiktoken的分词器有别于其他分词器,比如sentencepiece分词器。尤其在微调阶段,需要特别注意特殊token的使用。关于tokenizer的更多信息,以及微调时涉及的相关使用,请参阅文档。
Our tokenizer based on tiktoken is different from other tokenizers, e.g., sentencepiece tokenizer. You need to pay attention to special tokens, especially in finetuning. For more detailed information on the tokenizer and related use in fine-tuning, please refer to the documentation.
请注意:我们更新量化方案为基于AutoGPTQ的量化,提供Qwen-1.8B-Chat的Int4量化模型点击这里。相比此前方案,该方案在模型评测效果几乎无损,且存储需求更低,推理速度更优。
Note: we provide a new solution based on AutoGPTQ, and release an Int4 quantized model for Qwen-1.8B-Chat Click here, which achieves nearly lossless model effects but improved performance on both memory costs and inference speed, in comparison with the previous solution.
以下我们提供示例说明如何使用Int4量化模型。在开始使用前,请先保证满足要求(如torch 2.0及以上,transformers版本为4.32.0及以上,等等),并安装所需安装包:
Here we demonstrate how to use our provided quantized models for inference. Before you start, make sure you meet the requirements of auto-gptq (e.g., torch 2.0 and above, transformers 4.32.0 and above, etc.) and install the required packages:
pip install auto-gptq optimum
如安装auto-gptq遇到问题,我们建议您到官方repo搜索合适的预编译wheel。
随后即可使用和上述一致的用法调用量化模型:
If you meet problems installing auto-gptq, we advise you to check out the official repo to find a pre-build wheel.
Then you can load the quantized model easily and run inference as same as usual:
model = AutoModelForCausalLM.from_pretrained(
"Qwen/Qwen-1_8B-Chat-Int4",
device_map="auto",
trust_remote_code=True
).eval()
response, history = model.chat(tokenizer, "你好", history=None)
我们使用原始模型的FP32和BF16精度,以及量化过的Int8和Int4模型在基准评测上做了测试,结果如下所示:
We illustrate the model performance of both FP32, BF16, Int8 and Int4 models on the benchmark. Results are shown below:
| Quantization | MMLU | CEval (val) | GSM8K | Humaneval |
|---|---|---|---|---|
| FP32 | 43.4 | 57.0 | 33.0 | 26.8 |
| BF16 | 43.3 | 55.6 | 33.7 | 26.2 |
| Int8 | 43.1 | 55.8 | 33.0 | 27.4 |
| Int4 | 42.9 | 52.8 | 31.2 | 25.0 |
我们测算了FP32、BF16精度和Int8、Int4量化模型生成2048和8192个token的平均推理速度。如图所示:
We measured the average inference speed of generating 2048 and 8192 tokens under FP32, BF16 precision and Int8, Int4 quantization level, respectively.
| Quantization | FlashAttn | Speed (2048 tokens) | Speed (8192 tokens) |
|---|---|---|---|
| FP32 | v2 | 52.96 | 47.35 |
| BF16 | v2 | 54.09 | 54.04 |
| Int8 | v2 | 55.56 | 55.62 |
| Int4 | v2 | 71.07 | 76.45 |
| FP32 | v1 | 52.00 | 45.80 |
| BF16 | v1 | 51.70 | 55.04 |
| Int8 | v1 | 53.16 | 53.33 |
| Int4 | v1 | 69.82 | 67.44 |
| FP32 | Disabled | 52.28 | 44.95 |
| BF16 | Disabled | 48.17 | 45.01 |
| Int8 | Disabled | 52.16 | 52.99 |
| Int4 | Disabled | 68.37 | 65.94 |
具体而言,我们记录在长度为1的上下文的条件下生成8192个token的性能。评测运行于单张A100-SXM4-80G GPU,使用PyTorch 2.0.1和CUDA 11.4。推理速度是生成8192个token的速度均值。
In detail, the setting of profiling is generating 8192 new tokens with 1 context token. The profiling runs on a single A100-SXM4-80G GPU with PyTorch 2.0.1 and CUDA 11.4. The inference speed is averaged over the generated 8192 tokens.
我们测算了FP32、BF16精度和Int8、Int4量化模型生成2048个及8192个token(单个token作为输入)的峰值显存占用情况。结果如下所示:
We also profile the peak GPU memory usage for generating 2048 tokens and 8192 tokens (with single token as context) under FP32, BF16 or Int8, Int4 quantization level, respectively. The results are shown below.
| Quantization Level | Peak Usage for Encoding 2048 Tokens | Peak Usage for Generating 8192 Tokens |
|---|---|---|
| FP32 | 8.45GB | 13.06GB |
| BF16 | 4.23GB | 6.48GB |
| Int8 | 3.48GB | 5.34GB |
| Int4 | 2.91GB | 4.80GB |
上述性能测算使用此脚本完成。
The above speed and memory profiling are conducted using this script. <br>
与Qwen-1.8B预训练模型相同,Qwen-1.8B-Chat模型规模基本情况如下所示
The details of the model architecture of Qwen-1.8B-Chat are listed as follows
| Hyperparameter | Value |
|---|---|
| n_layers | 24 |
| n_heads | 16 |
| d_model | 2048 |
| vocab size | 151851 |
| sequence length | 8192 |
在位置编码、FFN激活函数和normalization的实现方式上,我们也采用了目前最流行的做法, 即RoPE相对位置编码、SwiGLU激活函数、RMSNorm(可选安装flash-attention加速)。
在分词器方面,相比目前主流开源模型以中英词表为主,Qwen-1.8B-Chat使用了约15万token大小的词表。
该词表在GPT-4使用的BPE词表cl100k_base基础上,对中文、多语言进行了优化,在对中、英、代码数据的高效编解码的基础上,对部分多语言更加友好,方便用户在不扩展词表的情况下对部分语种进行能力增强。
词表对数字按单个数字位切分。调用较为高效的tiktoken分词库进行分词。
For position encoding, FFN activation function, and normalization calculation methods, we adopt the prevalent practices, i.e., RoPE relative position encoding, SwiGLU for activation function, and RMSNorm for normalization (optional installation of flash-attention for acceleration).
For tokenization, compared to the current mainstream open-source models based on Chinese and English vocabularies, Qwen-1.8B-Chat uses a vocabulary of over 150K tokens. It first considers efficient encoding of Chinese, English, and code data, and is also more friendly to multilingual languages, enabling users to directly enhance the capability of some languages without expanding the vocabulary. It segments numbers by single digit, and calls the tiktoken tokenizer library for efficient tokenization.
对于Qwen-1.8B-Chat模型,我们同样评测了常规的中文理解(C-Eval)、英文理解(MMLU)、代码(HumanEval)和数学(GSM8K)等权威任务,同时包含了长序列任务的评测结果。由于Qwen-1.8B-Chat模型经过对齐后,激发了较强的外部系统调用能力,我们还进行了工具使用能力方面的评测。
提示:由于硬件和框架造成的舍入误差,复现结果如有波动属于正常现象。
For Qwen-1.8B-Chat, we also evaluate the model on C-Eval, MMLU, HumanEval, GSM8K, etc., as well as the benchmark evaluation for long-context understanding, and tool usage.
Note: Due to rounding errors caused by hardware and framework, differences in reproduced results are possible.
