Introduction

NNI (Neural Network Intelligence) is a toolkit to help users running automated machine learning experiments. The tool dispatches and runs trial jobs that generated by tuning algorithms to search the best neural architecture and/or hyper-parameters at different environments (e.g. local, remote servers and cloud).

Who should consider using NNI

• You want to try different AutoML algorithms for your training code (model) at local
• You want to run AutoML trial jobs in different environments to speed up search (e.g. remote servers and cloud)
• As a researcher and data scientist, you want to implement your own AutoML algorithms and compare with other algorithms
• As a ML platform owner, you want to support AutoML in your platform

Getting Started with NNI

Installation

Install through python pip

• requirements: python >= 3.5

pip3 install -v --user git+https://github.com/Microsoft/nni.git@v0.1
source ~/.bashrc

Quick start: run an experiment at local

Requirements:

• NNI installed on your local machine

Run the following command to create an experiment for [mnist]

    nnictl create --config ~/nni/examples/trials/mnist-annotation/config.yml

This command will start an experiment and a WebUI. The WebUI endpoint will be shown in the output of this command (for example, http://localhost:8080). Open this URL in your browser. You can analyze your experiment through WebUI, or browse trials' tensorboard.

Please refer to here for the GetStarted tutorial.
