In this paper, we transplant Mamba, a state-space language model, into VMamba, a vision backbone that works in linear time complexity. At the core of VMamba lies a stack of Visual State-Space (VSS) blocks with the 2D Selective Scan (SS2D) module. By traversing along four scanning routes, SS2D helps bridge the gap between the ordered nature of 1D selective scan and the non-sequential structure of 2D vision data, which facilitates the gathering of contextual information from various sources and perspectives. Based on the VSS blocks, we develop a family of VMamba architectures and accelerate them through a succession of architectural and implementation enhancements. Extensive experiments showcase VMamba’s promising performance across diverse visual perception tasks, highlighting its advantages in input scaling efficiency compared to existing benchmark models. ## Overview * [**VMamba**](https://arxiv.org/abs/2401.10166) serves as a general-purpose backbone for computer vision. <img src="assets/architecture.png" alt="architecture" width="80%"> * **2D-Selective-Scan of VMamba** <img src="assets/ss2d.png" alt="arch" width="80%"> * **VMamba has global effective receptive field** <img src="assets/erf.png" alt="erf" width="80%"> * **VMamba resembles Transformer-Based Methods in Activation Map** <img src="assets/attn.png" alt="attn" width="80%"> <img src="assets/activation_map.png" alt="activation" width="80%"> ## Main Results    :book: ***For details see [performance.md](./assets/performance.md).*** ### **Classification on ImageNet-1K** | name | pretrain | resolution |acc@1 | #params | FLOPs | TP. | Train TP. | configs/logs/ckpts | | :---: | :---: | :---: | :---: | :---: | :---: | :---: | :---: | :---: | | Swin-T | ImageNet-1K | 224x224 | 81.2 | 28M | 4.5G | 1244 |987 | -- | | Swin-S | ImageNet-1K | 224x224 | 83.2 | 50M | 8.7G | 718 |642 | -- | | Swin-B | ImageNet-1K | 224x224 | 83.5 | 88M | 15.4G | 458 |496 | -- | | VMamba-S[`s2l15`] | ImageNet-1K | 224x224 | 83.6 | 50M | 8.7G | 877 | 314| [config](classification/configs/vssm/vmambav2_small_224.yaml)/[log](https://github.com/MzeroMiko/VMamba/releases/download/%23v2cls/vssm_small_0229.txt)/[ckpt](https://github.com/MzeroMiko/VMamba/releases/download/%23v2cls/vssm_small_0229_ckpt_epoch_222.pth) | | VMamba-B[`s2l15`] | ImageNet-1K | 224x224 | 83.9 | 89M | 15.4G | 646 | 247 | [config](classification/configs/vssm/vmambav2_base_224.yaml)/[log](https://github.com/MzeroMiko/VMamba/releases/download/%23v2cls/vssm_base_0229.txt)/[ckpt](https://github.com/MzeroMiko/VMamba/releases/download/%23v2cls/vssm_base_0229_ckpt_epoch_237.pth) | | VMamba-T[`s1l8`] | ImageNet-1K | 224x224 | 82.6 | 30M | 4.9G | 1686| 571| [config](classification/configs/vssm/vmambav2v_tiny_224.yaml)/[log](https://github.com/MzeroMiko/VMamba/releases/download/%23v2cls/vssm1_tiny_0230s.txt)/[ckpt](https://github.com/MzeroMiko/VMamba/releases/download/%23v2cls/vssm1_tiny_0230s_ckpt_epoch_264.pth) | * *Models in this subsection is trained from scratch with random or manual initialization.

algrithm).* ## Getting Started ### Installation **Step 1: Clone the VMamba repository:** To get started, first clone the VMamba repository and navigate to the project directory: ```bash git clone https://github.com/MzeroMiko/VMamba.git cd VMamba ``` **Step 2: Environment Setup:** VMamba recommends setting up a conda environment and installing dependencies via pip. Use the following commands to set up your environment: Also, We recommend using the pytorch>=2.0, cuda>=11.8. But lower version of pytorch and CUDA are also supported. ***Create and activate a new conda environment*** ```bash conda create -n vmamba conda activate vmamba ``` ***Install Dependencies*** ```bash pip install -r requirements.txt cd kernels/selective_scan && pip install . ```  ***Check Selective Scan (optional)*** * If you want to check the modules compared with `mamba_ssm`, install [`mamba_ssm`](https://github.com/state-spaces/mamba) first! * If you want to check if the implementation of `selective scan` of ours is the same with `mamba_ssm`, `selective_scan/test_selective_scan.py` is here for you. Change to `MODE = "mamba_ssm_sscore"` in `selective_scan/test_selective_scan.py`, and run `pytest selective_scan/test_selective_scan.py`. * If you want to check if the implementation of `selective scan` of ours is the same with reference code (`selective_scan_ref`), change to `MODE = "sscore"` in `selective_scan/test_selective_scan.py`, and run `pytest selective_scan/test_selective_scan.py`. * `MODE = "mamba_ssm"` stands for checking whether the results of `mamba_ssm` is close to `selective_scan_ref`, and `"sstest"` is preserved for development. * If you find `mamba_ssm` (`selective_scan_cuda`) or `selective_scan` ( `selctive_scan_cuda_core`) is not close enough to `selective_scan_ref`, and the test failed, do not worry. Check if `mamba_ssm` and `selective_scan` are close enough [instead](https://github.com/state-spaces/mamba/pull/161). * ***If you are interested in selective scan, you can check [mamba](https://github.com/state-spaces/mamba), [mamba-mini](https://github.com/MzeroMiko/mamba-mini), [mamba.py](https://github.com/alxndrTL/mamba.py) [mamba-minimal](https://github.com/johnma2006/mamba-minimal) for more information.*** ***Dependencies for `Detection` and `Segmentation` (optional)*** ```bash pip install mmengine==0.10.1 mmcv==2.1.0 opencv-python-headless ftfy regex pip install mmdet==3.3.0 mmsegmentation==1.2.2 mmpretrain==1.2.0 ``` ### Model Training and Inference **Classification** To train VMamba models for classification on ImageNet, use the following commands for different configurations: ```bash python -m torch.distributed.launch --nnodes=1 --node_rank=0 --nproc_per_node=8 --master_addr="127.0.0.1" --master_port=29501 main.py --cfg </path/to/config> --batch-size 128 --data-path </path/of/dataset> --output /tmp ``` If you only want to test the performance (together with params and flops): ```bash python -m torch.distributed.launch --nnodes=1 --node_rank=0 --nproc_per_node=1 --master_addr="127.0.0.1" --master_port=29501 main.py --cfg </path/to/config> --batch-size 128 --data-path </path/of/dataset> --output /tmp --pretrained </path/of/checkpoint> ``` ***please refer to [modelcard](./modelcard.sh) for more details.*** **Detection and Segmentation** To evaluate with `mmdetection` or `mmsegmentation`: ```bash bash ./tools/dist_test.sh </path/to/config> </path/to/checkpoint> 1 ``` *use `--tta` to get the `mIoU(ms)` in segmentation* To train with `mmdetection` or `mmsegmentation`: ```bash bash ./tools/dist_train.sh </path/to/config> 8 ``` For more information about detection and segmentation tasks, please refer to the manual of [`mmdetection`](https://mmdetection.readthedocs.io/en/latest/user_guides/train.html) and [`mmsegmentation`](https://mmsegmentation.readthedocs.io/en/latest/user_guides/4_train_test.html). Remember to use the appropriate backbone configurations in the `configs` directory. ### Analysis Tools VMamba includes tools for visualizing mamba "attention" and effective receptive field, analysing throughput and train-throughput. Use the following commands to perform analysis: ```bash # Visualize Mamba "Attention" CUDA_VISIBLE_DEVICES=0 python analyze/attnmap.py # Analyze the effective receptive field CUDA_VISIBLE_DEVICES=0 python analyze/erf.py # Analyze the throughput and train throughput CUDA_VISIBLE_DEVICES=0 python analyze/tp.py ``` ***We also included other analysing tools that we may use in this project.
