## Introduction MMPreTrain is an open source pre-training toolbox based on PyTorch. It is a part of the [OpenMMLab](https://openmmlab.com/) project. The `main` branch works with **PyTorch 1.8+**. ### Major features - Various backbones and pretrained models - Rich training strategies (supervised learning, self-supervised learning, multi-modality learning etc.) - Bag of training tricks - Large-scale training configs - High efficiency and extensibility - Powerful toolkits for model analysis and experiments - Various out-of-box inference tasks. - Image Classification - Image Caption - Visual Question Answering - Visual Grounding - Retrieval (Image-To-Image, Text-To-Image, Image-To-Text) https://github.com/open-mmlab/mmpretrain/assets/26739999/e4dcd3a2-f895-4d1b-a351-fbc74a04e904 ## What's new 🌟 v1.2.0 was released in 04/01/2023 - Support LLaVA 1.5. - Implement of RAM with a gradio interface. 🌟 v1.1.0 was released in 12/10/2023 - Support Mini-GPT4 training and provide a Chinese model (based on Baichuan-7B) - Support zero-shot classification based on CLIP. 🌟 v1.0.0 was released in 04/07/2023 - Support inference of more **multi-modal** algorithms, such as [**LLaVA**](./configs/llava/), [**MiniGPT-4**](./configs/minigpt4), [**Otter**](./configs/otter/), etc. - Support around **10 multi-modal** datasets! - Add [**iTPN**](./configs/itpn/), [**SparK**](./configs/spark/) self-supervised learning algorithms. - Provide examples of [New Config](./mmpretrain/configs/) and [DeepSpeed/FSDP with FlexibleRunner](./configs/mae/benchmarks/). Here are the documentation links of [New Config](https://mmengine.readthedocs.io/en/latest/advanced_tutorials/config.html#a-pure-python-style-configuration-file-beta) and [DeepSpeed/FSDP with FlexibleRunner](https://mmengine.readthedocs.io/en/latest/api/generated/mmengine.runner.FlexibleRunner.html#mmengine.runner.FlexibleRunner). 🌟 Upgrade from MMClassification to MMPreTrain - Integrated Self-supervised learning algorithms from **MMSelfSup**, such as **MAE**, **BEiT**, etc. - Support **RIFormer**, a simple but effective vision backbone by removing token mixer. - Refactor dataset pipeline visualization. - Support **LeViT**, **XCiT**, **ViG**, **ConvNeXt-V2**, **EVA**, **RevViT**, **EfficientnetV2**, **CLIP**, **TinyViT** and **MixMIM** backbones. This release introduced a brand new and flexible training & test engine, but it's still in progress. Welcome to try according to [the documentation](https://mmpretrain.readthedocs.io/en/latest/). And there are some BC-breaking changes. Please check [the migration tutorial](https://mmpretrain.readthedocs.io/en/latest/migration.html). Please refer to [changelog](https://mmpretrain.readthedocs.io/en/latest/notes/changelog.html) for more details and other release history. ## Installation Below are quick steps for installation: ```shell conda create -n open-mmlab python=3.8 pytorch==1.10.1 torchvision==0.11.2 cudatoolkit=11.3 -c pytorch -y conda activate open-mmlab pip install openmim git clone https://github.com/open-mmlab/mmpretrain.git cd mmpretrain mim install -e . ``` Please refer to [installation documentation](https://mmpretrain.readthedocs.io/en/latest/get_started.html) for more detailed installation and dataset preparation. For multi-modality models support, please install the extra dependencies by: ```shell mim install -e ".[multimodal]" ``` ## User Guides We provided a series of tutorials about the basic usage of MMPreTrain for new users: - [Learn about Configs](https://mmpretrain.readthedocs.io/en/latest/user_guides/config.html) - [Prepare Dataset](https://mmpretrain.readthedocs.io/en/latest/user_guides/dataset_prepare.html) - [Inference with existing models](https://mmpretrain.readthedocs.io/en/latest/user_guides/inference.html) - [Train](https://mmpretrain.readthedocs.io/en/latest/user_guides/train.html) - [Test](https://mmpretrain.readthedocs.io/en/latest/user_guides/test.html) - [Downstream tasks](https://mmpretrain.readthedocs.io/en/latest/user_guides/downstream.html) For more information, please refer to [our documentation](https://mmpretrain.readthedocs.io/en/latest/). ## Model zoo Results and models are available in the [model zoo](https://mmpretrain.readthedocs.io/en/latest/modelzoo_statistics.html).
