英文:
error in installing knn plugin for elasticsearch
问题
我正在尝试安装KNN插件以使以下代码正常工作：
from elasticsearch import Elasticsearch
from elasticsearch.helpers import bulk
es = Elasticsearch('http://127.0.0.1:9200', verify_certs=False)
settings={
"settings":{
"index": {
"knn": "true",
"knn.space_type": "cosinesimil"
}
},
"mappings":{
"dynamic": "true",
"_source":{
"enabled":"true"
},
"properties":{
"vector": {
"type": "knn_vector",
"dimension": "768"
}
}
}
}
es.indices.create(index = 'document_embeddings', ignore=[400,404], body = settings)
但是我收到以下错误：
{'error': {'root_cause': [{'type': 'illegal_argument_exception',
'reason': 'unknown setting [index.knn] please check that any required plugins are installed, or check the breaking changes documentation for removed settings'}],
'type': 'illegal_argument_exception',
'reason': 'unknown setting [index.knn] please check that any required plugins are installed, or check the breaking changes documentation for removed settings',
'suppressed': [{'type': 'illegal_argument_exception',
'reason': 'unknown setting [index.knn.space_type] please check that any required plugins are installed, or check the breaking changes documentation for removed settings'}]},
'status': 400}
我认为问题是KNN插件未安装，因此我正在以下方式安装，其中zip文件从这里下载：
-> Installing file://elastiknn-8.6.1.0.zip
-> Downloading file://elastiknn-8.6.1.0.zip
-> Failed installing file://elastiknn-8.6.1.0.zip
-> Rolling back file://elastiknn-8.6.1.0.zip
-> Rolled back file://elastiknn-8.6.1.0.zip
Exception in thread "main" java.net.UnknownHostException: elastiknn-8.6.1.0.zip
at java.base/sun.nio.ch.NioSocketImpl.connect(NioSocketImpl.java:560)
at java.base/java.net.Socket.connect(Socket.java:666)
...
我运行的安装插件的命令是：
sudo bin/elasticsearch-plugin install file://elastiknn-8.6.1.0.zip
我的elasticsearch版本是8.6.1，看起来与elastiknn版本完全兼容。请问有人能告诉我如何在我的mac上设置KNN插件与elasticsearch一起使用吗？谢谢！ 1: https://github.com/alexklibisz/elastiknn/releases/tag/8.6.1.0-MAIN1517-SNAPSHOT

I am trying to install the KNN plugin to get the following code working:
from elasticsearch import Elasticsearch
from elasticsearch.helpers import bulk
es = Elasticsearch('http://127.0.0.1:9200',verify_certs=False)
settings={
"settings":{
"index": {
"knn": "true",
"knn.space_type": "cosinesimil"
}
},
"mappings":{
"dynamic": "true",
"_source":{
"enabled":"true"
},
"properties":{
"vector": {
"type": "knn_vector",
"dimension": "768"
}
}
}
}
es.indices.create(index = 'document_embeddings', ignore=[400,404], body = settings)
but am getting the following error:
{'error': {'root_cause': [{'type': 'illegal_argument_exception',
'reason': 'unknown setting [index.knn] please check that any required plugins are installed, or check the breaking changes documentation for removed settings'}],
'type': 'illegal_argument_exception',
'reason': 'unknown setting [index.knn] please check that any required plugins are installed, or check the breaking changes documentation for removed settings',
'suppressed': [{'type': 'illegal_argument_exception',
'reason': 'unknown setting [index.knn.space_type] please check that any required plugins are installed, or check the breaking changes documentation for removed settings'}]},
'status': 400}
I think the cause is that the KNN plugin is not installed, so I am installing it in the following way where thee zip file is downloaded from here.

The command that I am running to install the plugin is:
sudo bin/elasticsearch-plugin install file://elastiknn-8.6.1.0.zip
The version of my elasticsearch i.e. 8.6.1 seems perfectly compatible with that of elastiknn. Can anyone please tell me how can I get a working setup of KNN with elasticsearch in my mac? Thanks!
