一、encoding()_编码

clip_client提供 encode（）函数，允许您以流和同步/异步方式将句子、图像发送到服务器。这里的编码意味着获取文本或图像的固定长度矢量表示。
encoding()接收两种类型的输入，输入不同，输出的数据类型也随之不同
1、输入可迭代的字符串类型，例如字符串列表，字符串元组，字符串生成器，对应的输出的是numpy.ndarray.
2、输入可迭代的Document数据类型，例如List[Document], DocumentArray, Generator[Document]，对应的输出的数据类型是DocumentArray

1、作为文档可迭代对象的输入

类型url格式，包括相对路径，绝对路径http，url等都被视为图片数据，否则视为句子，
下面实例中的’apple.png’为本地的一张图片,'https://bpic.588ku.com/element_origin_min_pic/19/05/24/f862579f1d73afc60967a706238eac6d.jpg’是网络上的一张图片路径,

from clip_client import Client

c = Client('grpc://127.0.0.1:51000')

r = c.encode(
    [
        'she smiled, with pain',
        '追风赶月莫停留，平芜尽处是春山！',
        'apple.png',
        'https://bpic.588ku.com/element_origin_min_pic/19/05/24/f862579f1d73afc60967a706238eac6d.jpg',
        'data:image/gif;base64,R0lGODlhEAAQAMQAAORHHOVSKudfOulrSOp3WOyDZu6QdvCchPGolfO0o/XBs/fNwfjZ0frl3/zy7wAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAACH5BAkAABAALAAAAAAQABAAAAVVICSOZGlCQAosJ6mu7fiyZeKqNKToQGDsM8hBADgUXoGAiqhSvp5QAnQKGIgUhwFUYLCVDFCrKUE1lBavAViFIDlTImbKC5Gm2hB0SlBCBMQiB0UjIQA7',
    ]
)
print(r)

输出如下

2、作为文档可迭代对象的输入

此功能使用 DocArray，它作为上游依赖项一起安装。您不需要单独安装 DocArray。

from clip_client import Client
from docarray import Document
c = Client('grpc://127.0.0.1:51000')

da = [
    Document(text='she smiled, with pain'),
    Document(uri='apple.png'),
    Document(uri='apple.png').load_uri_to_image_tensor(),
    Document(blob=open('apple.png', 'rb').read()),
    Document(uri='https://clip-as-service.jina.ai/_static/favicon.png'),
    Document(
        uri='data:image/gif;base64,R0lGODlhEAAQAMQAAORHHOVSKudfOulrSOp3WOyDZu6QdvCchPGolfO0o/XBs/fNwfjZ0frl3/zy7wAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAACH5BAkAABAALAAAAAAQABAAAAVVICSOZGlCQAosJ6mu7fiyZeKqNKToQGDsM8hBADgUXoGAiqhSvp5QAnQKGIgUhwFUYLCVDFCrKUE1lBavAViFIDlTImbKC5Gm2hB0SlBCBMQiB0UjIQA7'
    ),
]

r = c.encode(da)
print("======输出摘要===========")
print(r.summary())
print('=======输出编码==========')
print(r.embeddings)

输出如下
在这里插入图片描述

3、异步编码

import asyncio

from clip_client import Client
c = Client('grpc://127.0.0.1:51000')


async def another_heavylifting_job():
    # can be writing to database, downloading large file
    # big IO ops
    await asyncio.sleep(3)


async def main():
    t1 = asyncio.create_task(another_heavylifting_job())
    t2 = asyncio.create_task(c.aencode(['hello world'] * 100))
    await asyncio.gather(t1, t2)


asyncio.run(main())

二、ranking() _排序

这个函数的功能是给定一个句子，对多张图片进行排序或给一张图片对多个句子进行排序，此处和我的任务关系不大，就不再赘述

三、Indexing(）_索引

ps:感觉像生成一个数据库，向里面存储数据，实例如下

from clip_client import Client
from docarray import Document
c = Client('grpc://127.0.0.1:51000')

da = [
    Document(text='she smiled, with pain'),
    Document(uri='apple.png'),
    Document(uri='apple.png').load_uri_to_image_tensor(),
    Document(blob=open('apple.png', 'rb').read()),
    Document(uri='https://clip-as-service.jina.ai/_static/favicon.png'),
    Document(
        uri='data:image/gif;base64,R0lGODlhEAAQAMQAAORHHOVSKudfOulrSOp3WOyDZu6QdvCchPGolfO0o/XBs/fNwfjZ0frl3/zy7wAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAACH5BAkAABAALAAAAAAQABAAAAVVICSOZGlCQAosJ6mu7fiyZeKqNKToQGDsM8hBADgUXoGAiqhSvp5QAnQKGIgUhwFUYLCVDFCrKUE1lBavAViFIDlTImbKC5Gm2hB0SlBCBMQiB0UjIQA7'
    ),
]

r = c.index(da)
print(r.summary())

现在返回结果是一个DocumentArray，我们可以得到他的摘要如下

四、Searching（）_搜索

您可以设置参数（默认值为）来控制要检索的最相似文档的数量。limit10

import asyncio

from clip_client import Client
from docarray import Document
c = Client('grpc://127.0.0.1:51000')

da = [
    Document(text='she smiled, with pain'),
    Document(text='she smiles, with pain'),
    Document(uri='apple.png'),
    Document(uri='apple.png').load_uri_to_image_tensor(),
    Document(blob=open('apple.png', 'rb').read()),
    Document(uri='https://clip-as-service.jina.ai/_static/favicon.png'),
    Document(
        uri='data:image/gif;base64,R0lGODlhEAAQAMQAAORHHOVSKudfOulrSOp3WOyDZu6QdvCchPGolfO0o/XBs/fNwfjZ0frl3/zy7wAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAACH5BAkAABAALAAAAAAQABAAAAVVICSOZGlCQAosJ6mu7fiyZeKqNKToQGDsM8hBADgUXoGAiqhSvp5QAnQKGIgUhwFUYLCVDFCrKUE1lBavAViFIDlTImbKC5Gm2hB0SlBCBMQiB0UjIQA7'
    ),
]

r = c.index(da)
result = c.search(['smile'], limit=100)

print(result['@m', ['text', 'scores__cosine']])
