MIM Installs OpenMMLab packages
MIM provides a unified interface for launching and installing OpenMMLab projects and their extensions, and managing the OpenMMLab model zoo.
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.
This project is released under the Apache 2.0 license.
v0.1.1 was released in 13/6/2021.
You can use .mimrc for customization. Now we support customize default values of each sub-command. Please refer to customization.md for details.
We provide some examples of how to build custom projects based on OpenMMLAB codebases and MIM in 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.
Please refer to installation.md for installation.
