README
faiss-server
faiss-server provides gRPC services to for similarity search using faiss. It is written in C++ and now supports only CPU environments.
Installation
Currently, installation is from source only.
$ git clone https://github.com/ynqa/faiss-server
$ cd faiss-server
To build faiss-server on your local, please use cmake.
$ mkdir build; cd build
$ cmake ..
$ make
[Beta] To build as docker image:
$ docker build -t faiss-server .
Demo
- Create indexed file, which is composed of the word vectors. Indexed words are on text8 corpus and those vectors are trained by word2vec model of gensim.
$ python example/indexing/indexing.py
- Select the indexed file and then execute faiss-server.
$ ./build/bin/faiss_server -file_path example/indexing/faiss.index
- If you build with docker:
$ docker run -p 8080:8080 -v $(pwd)/example/indexing:/tmp faiss-server -file_path /tmp/faiss.index
- Throw the requests for similarity search
$ PYTHONPATH=python python example/client/search.py
Usage
faiss_server:
-file_path (index file name) type: string default: ""
-host (host of faiss server) type: string default: "0.0.0.0"
-port (port of faiss server) type: string default: "8080"
-top_k (default number of neighbor) type: uint64 default: 5
