NNI (Neural Network Intelligence) is a toolkit to help users run automated machine learning (AutoML) experiments. The tool dispatches and runs trial jobs generated by tuning algorithms to search the best neural architecture and/or hyper-parameters in different environments like local machine, remote servers and cloud.
- Those who want to try different AutoML algorithms in their training code (model) at their local machine.
- Those who want to run AutoML trial jobs in different environments to speed up search (e.g. remote servers and cloud).
- Researchers and data scientists who want to implement their own AutoML algorithms and compare it with other algorithms.
- ML Platform owners who want to support AutoML in their platform.
Install through pip

This project welcomes contributions and suggestions, we use GitHub issues for tracking requests and bugs.
Issues with the good first issue label are simple and easy-to-start ones that we recommend new contributors to start with.
To set up environment for NNI development, refer to the instruction: Set up NNI developer environment
Before start coding, review and get familiar with the NNI Code Contribution Guideline: Contributing
We are in construction of the instruction for How to Debug, you are also welcome to contribute questions or suggestions on this area.
