GraphPipe

Dead Simple ML Model Serving via a Standard Protocol

What is it?

GraphPipe is a protocol and collection of software designed to simplify machine learning model deployment and decouple it from framework-specific model implementations.

The existing solutions for model serving are inconsistent and/or inefficient. There is no consistent protocol for communicating with these model servers so it is often necessary to build custom clients for each workload. GraphPipe solves these problems by standardizing on an efficient communication protocol and providing simple model servers for the major ML frameworks.

We hope that open sourcing GraphPipe makes the model serving landscape a friendlier place. See more about why we built it here.

Features

• A minimalist machine learning transport specification based on flatbuffers
• Simple, efficient reference model servers for Tensorflow, Caffe2, and ONNX.
• Efficient client implementations in Go, Python, and Java.

What is in this repo?

This repo contains documentation as well as the flatubuffer definition files that are used by other language specific repos. If you are looking for GraphPipe clients, servers, and example code, check out our other GraphPipe repos:

• https://github.com/oracle/graphpipe-go - the GraphPipe go client library
• https://github.com/oracle/graphpipe-go/tree/master/cmd/graphpipe-tf - Go implementation of a GraphPipe TensorFlow model server
• https://github.com/oracle/graphpipe-go/tree/master/cmd/graphpipe-onnx - a Go implementation a GraphPipe ONNX/Caffe2 model server
• https://github.com/oracle/graphpipe-py - the GraphPipe client library for Python
• https://github.com/oracle/graphpipe-tf-py - a Python implementation of a remote operation client for TensorFlow, as well as some example server implementations

Building flatbuffer definitions

If you've got flatc installed you can just make all but if you don't want to install it, you can export USE_DOCKER=1 and then make all. (Remember, make needs vars exported, not just on the command-line where you run make).

This will produce the go, c, and python libraries, which can then be copied into their projects graphpipe-go, graphpipe-tf-py, and graphpipe-py, respectively.
