visual-search-backend

BFF over a Tensorflow and FAISS index gRPC server for visual search.

Requirements

• Go 1.11 and later
• gRPC server providing the Tensorflow model
• gRPC server providing the FAISS index

And then install Tensorflow and Tensorflow serving Go packages:

git clone -b r1.15 https://github.com/tensorflow/tensorflow.git
git clone -b r1.15 https://github.com/tensorflow/serving.git
GO111MODULE=off go run protoc.go
cd proto/tensorflow/core && go mod init github.com/tensorflow/tensorflow/tensorflow/go/core && cd -
go build ./proto/tensorflow/serving

Compiling and creating the Docker image

Compiling:

make build

Create Docker image:

make docker

Run

To run the visual search backend, create a conf.yaml from the example file to put your values, and finally run:

./visual-search-backend

Or you can your values through the corresponding parameters:

visual-search-backend
