一款易用的神经搜索框架。神经搜索是指用非结构化数据，搜索非结构化数据。Jina 简化了神经搜索系统的搭建流程，使开发者可以快速构建以图搜图、以文字搜图、问答机器人、照片去重、海量标签分类等应用 ```python from docarray import Document, DocumentArray from jina import Executor, Flow, requests class PreprocImg(Executor): @requests async def foo(self, docs: DocumentArray, **kwargs): for d in docs: ( d.load_uri_to_image_tensor(200, 200) # load .set_image_tensor_normalization() # normalize color .set_image_tensor_channel_axis( -1, 0 ) # switch color axis for the PyTorch model later ) ```
