本文介绍: 数据转换是 Towhee 的核心；管道只是在有向无环图中连接在一起的一系列转换。所有预构建的 Towhee 管道都有代表当前任务的名称。

安装Towhee

pip3 install towhee

如果你想在 towhee 中安装模型

pip3 install towhee.models

打开python终端

python3

引入towhee

数据转换是 Towhee 的核心；管道只是在有向无环图中连接在一起的一系列转换。所有预构建的 Towhee 管道都有代表当前任务的名称。

from towhee import AutoPipes

声明一个 sentence_embedding 的管道

p = AutoPipes.pipeline('sentence_embedding')

运行管道，获取向量值

output = p('Hello World.').get()

打印向量值

print(output)
