XNAS is an effective, modular and flexible Neural Architecture Search (NAS) repository, which aims to provide a common framework and baselines for the NAS community. It is originally designed to decouple the search space, search algorithm and performance evaluation strategy to achieve freely combinable NAS.

This project is now supported by PengCheng Lab.

For more information and API usages, please refer to our Documentation.

Based on a common division of NAS, the project is organized by search space, search algorithm, and evaluation strategy. The project currently supports the content shown below. Each row of the table represents a search algorithm and each column represents the search space.

We also provide the interpretation of papers and experimental records for each algorithm. For more information, please refer to the links in the "Docs" column.

We are gradually providing support for more settings.

To run XNAS, python>=3.7 and pytorch=1.9 are required. Other versions of PyTorch may also work well, but there are potential API differences that can cause warnings to be generated.

For detailed instructions, please refer to get_started.md and data_preparation.md in our docs.

We welcome contributions to the library along with any potential issues or suggestions.

Please refer to Contributing.md in our docs for more information.
