llamafile

在本地运行大型语言模型的最简单方法之一是使用 llamafile。llamafile 将模型权重和特殊编译版本的 llama.cpp 打包成单个文件,可在大多数计算机上运行而无需额外依赖。它们还内置了嵌入式推理服务器,提供与模型交互的 API 接口。

  1. HuggingFace 下载 llamafile
  2. 使文件可执行
  3. 运行文件

这是一个展示所有3个设置步骤的简单bash脚本:

Terminal window
# Download a llamafile from HuggingFace
wget https://huggingface.co/jartine/TinyLlama-1.1B-Chat-v1.0-GGUF/resolve/main/TinyLlama-1.1B-Chat-v1.0.Q5_K_M.llamafile
# Make the file executable. On Windows, instead just rename the file to end in ".exe".
chmod +x TinyLlama-1.1B-Chat-v1.0.Q5_K_M.llamafile
# Start the model server. Listens at http://localhost:8080 by default.
./TinyLlama-1.1B-Chat-v1.0.Q5_K_M.llamafile --server --nobrowser --embedding

您的模型推理服务器默认监听 localhost:8080。

如果您在 Colab 上打开这个笔记本,您可能需要安装 LlamaIndex 🦙。

%pip install llama-index-llms-llamafile
!pip install llama-index
from llama_index.llms.llamafile import Llamafile
llm = Llamafile(temperature=0, seed=0)
resp = llm.complete("Who is Octavia Butler?")
print(resp)
Octavia Butler was an American science fiction and fantasy writer who is best known for her groundbreaking work in the genre. She was born on August 26, 1947, in Philadelphia, Pennsylvania, to a family of educators. Her father, Dr. George Butler, was a professor of English at Temple University, while her mother, Dorothy Butler, was an elementary school teacher.
Octavia grew up in the city and attended public schools until she graduated from high school. She then went on to earn a bachelor's degree in English literature from Temple University and a master's degree in education from the University of Pennsylvania.
After graduating, Butler worked as an elementary school teacher for several years before pursuing her passion for writing full-time. She began publishing short stories in science fiction and fantasy magazines in the 1970s, and her work quickly gained recognition.
Her first novel, Kindred, was published in 1979 and became a bestseller. It was followed by several other novels that explored themes of race, gender, and science fiction. Butler's writing style was characterized by its vivid imagery, complex characters, and thought-provoking themes.
In addition to her writing, Butler also worked as an editor for various science fiction and fantasy magazines and served as a consultant on several television shows and films. She died in 2016 at the age of 67 due to complications from cancer.

警告:TinyLlama 对奥克塔维亚·巴特勒的上述描述包含大量虚假信息。 例如,她出生于加利福尼亚州而非宾夕法尼亚州。关于其家庭背景与教育经历的信息均属虚构。她从未担任过小学教师,而是通过从事一系列临时工作来集中精力进行创作。其作品并未“迅速获得认可”:她在1970年左右售出第一篇短篇小说,但直到14年后——1984年其短篇小说《言语之声》荣获雨果奖时——才真正崭露头角。请参阅维基百科获取奥克塔维亚·巴特勒的真实生平资料。

在这个示例笔记本中,我们使用TinyLlama模型主要是因为它体积小,因此出于示例目的下载速度快。更大的模型可能产生更少的幻觉。但这应该提醒我们,大型语言模型经常说谎,即使是那些知名度足以拥有维基百科页面的主题。通过自己的研究来验证它们的输出非常重要。
