Vega ver1.2.0 released:


Vega is an AutoML algorithm tool chain developed by Noah's Ark Laboratory, the main features are as follows:

  1. Full pipeline capailities: The AutoML capabilities cover key functions such as Hyperparameter Optimization, Data Augmentation, Network Architecture Search (NAS), Model Compression, and Fully Train. These functions are highly decoupled and can be configured as required, construct a complete pipeline.
  2. Industry-leading AutoML algorithms: provides Noah's Ark Laboratory's self-developed industry-leading algorithm(Benchmark) and Model Zoo to download the State-of-the-art (SOTA) model.
  3. Fine-grained network search space: The network search space can be freely defined, and rich network architecture parameters are provided for use in the search space. The network architecture parameters and model training hyperparameters can be searched at the same time, and the search space can be applied to Pytorch, TensorFlow and MindSpore.
  4. High-concurrency neural network training capability: Provides high-performance trainers to accelerate model training and evaluation.
  5. Multi-Backend: PyTorch, TensorFlow, MindSpore(trial)

Obtaining and Installing

Install Vega and the open source softwares that Vega depends on:

pip3 install --user noah-vega
python3 -m

For more detail, please refer installation guide. If you want to deploy Vega in local cluster, see the deployment guide .

Usage Guide

The Vega is highly modularized. You can configure the search space, search algorithm in a pipeline way. To run the Vega application is to load the configuration file and complete the AutoML process based on the configuration. Vega provides detailed operation examples for your reference. For details, see the examples . Example of running CARS algorithm:

cd examples
python3 ./ ./nas/cars/cars.yml -b pytorch

Therefore, before using the Vega, you need to fully understand the meaning of the configuration items. For details, see the Configuration Guide.


Before running an example, you need to configure the directory where the dataset and pre-trained models are located in the algorithm configuration file. Please refer to Example Reference .

Developer Guide

The Vega framework components are decoupled, and each functional component is combined using the registration mechanism to facilitate function and algorithm extension. For details about the Vega architecture and main mechanisms, see the Developer Guide .

In addition, you can refer to the Quick Start Guide to implement a simple network search function and quickly enter the Vega application development through practice.

During the development of the Vega application, the first problem is how to introduce the service data set to the Vega application. For details, see the Dataset Guide .

For different algorithms, you can refer doc Algorithm Development Guide . You can add the new algorithm to Vega step by step based on the example provided in this document.

In most Automl algorithms, the search space is closely related to the network. We try to unify the definition of the search space so that the same search space can adapt to different search algorithms. This is called the Fine-Grained Search Space Guide . Welcome to try it.

Of course, this document cannot solve all the problems. If you have any questions, please feel free to provide feedback through the issue. We will reply to you and solve your problems in a timely manner.
