MIM: Simplifying OpenMMLab Package Management
MIM, short for "MIM Installs OpenMMLab Packages," is a unified interface designed to simplify the installation and management of OpenMMLab projects, extensions, and model zoo. This tool is particularly handy for those involved in deep learning and computer vision projects using OpenMMLab libraries. Here’s a detailed look into what MIM offers:
Key Features
1. Package Management: MIM acts as a manager for OpenMMLab codebases, allowing users to install or uninstall packages with ease. Whether you're setting up your environment or updating components, MIM takes the hassle out of manual installations.
2. Model Management: Handling complex model zoos can be a daunting task. MIM addresses this by providing tools to manage the OpenMMLab model zoo. You can download model checkpoints by name or search for checkpoints that match specific criteria, streamlining the process of accessing powerful pre-trained models.
3. Unified Entrypoint for Scripts:
MIM provides a unified approach to executing any script across all OpenMMLab codebases. This feature ensures training, testing, and inference operations are more accessible than ever. Additionally, it includes a gridsearch command for conducting comprehensive hyper-parameter searches.
Customization
MIM allows for project customization through a configuration file known as .mimrc. This customization supports setting default values for various sub-commands, enabling users to tailor the tool to their specific project needs. More details can be accessed in the customization guide.
Building Custom Projects
For developers looking to extend OpenMMLab codebases or create new projects, MIM offers tools and examples through the MIM-Example. This setup allows developers to focus on innovation without the overhead of managing scripts and dependencies.
Installation and Usage
The installation guide for MIM can be found in the installation documentation. Once installed, MIM leverages command-line operations for key tasks, including installing/uninstalling packages, searching for models, and handling complex training and testing routines using powerful APIs.
For instance:
-
To install a package:
mim install mmcv-full -
To uninstall a package:
mim uninstall mmcv-full -
To search and download models:
mim search mmcls --config resnet18_8xb16_cifar10 mim download mmcls --config resnet18_8xb16_cifar10
Command Summary
MIM provides a suite of commands to facilitate various tasks:
- install/uninstall: Manage package installations.
- list/search: Explore available packages and models.
- download/train/test: Handle models and execute scripts with provided configurations.
- run/gridsearch: Execute specific operations or conduct hyper-parameter searches with ease.
Licensing and Contributions
MIM is made available under the Apache 2.0 license, welcoming contributions from the community to enhance its functionality further. If you're interested in contributing, check the detailed guidelines in the contributing document.
