openmim 0.3.9
MIM Installs OpenMMLab packages
Requires Python: >=3.6

# MIM: MIM Installs OpenMMLab Packages

MIM provides a unified interface for launching and installing OpenMMLab projects and their extensions, and managing the OpenMMLab model zoo.

## Major Features

- **Package Management**

  You can use MIM to manage OpenMMLab codebases, install or uninstall them conveniently.

- **Model Management**

  You can use MIM to manage OpenMMLab model zoo, e.g., download checkpoints by name, search checkpoints that meet specific criteria.

- **Unified Entrypoint for Scripts**

  You can execute any script provided by all OpenMMLab codebases with unified commands. Train, test and inference become easier than ever. Besides, you can use `gridsearch` command for vanilla hyper-parameter search.

## License

This project is released under the [Apache 2.0 license](LICENSE).

## Changelog

v0.1.1 was released in 13/6/2021.

## Customization

You can use `.mimrc` for customization. Now we support customize default values of each sub-command. Please refer to [customization.md](docs/en/customization.md) for details.

## Build custom projects with MIM

We provide some examples of how to build custom projects based on OpenMMLAB codebases and MIM in [MIM-Example](https://github.com/open-mmlab/mim-example).
Without worrying about copying codes and scripts from existing codebases, users can focus on developing new components and MIM helps integrate and run the new project.

## Installation

Please refer to [installation.md](docs/en/installation.md) for installation.
