🛠Install

conda create -n UNetMamba-main python=3.8
conda activate UNetMamba-main
pip install -r UNetMamba/requirements.txt

💁Tips: If you're having difficulty in installing "causal_conv1d" or "mamba_ssm", please refer to causal_conv1d or mamba_ssm to download the wheel files and then pip install them. For our UNetMamba, we installed both "causal_conv1d-1.2.0.post2+cu118torch2.0cxx11abiFALSE-cp38-cp38-linux_x86_64.whl" and "mamba_ssm-1.1.1+cu118torch2.0cxx11abiFALSE-cp38-cp38-linux_x86_64.whl". Moreover, UNetMamba is also compatible with the newest version of "causal_conv1d" and "mamba_ssm", please feel free to try😁.

--mode "val" --split-size 1024 --stride 1024 --gt

🏋Training

"-c" means the path of the config, use different config to train different models in different datasets.

python UNetMamba/train.py -c UNetMamba/config/loveda/unetmamba.py
python UNetMamba/train.py -c UNetMamba/config/vaihingen/unetmamba.py

🎯Testing

"-c" denotes the path of the config, Use different config to test different models in different datasets

"-o" denotes the output path

"-t" denotes the test time augmentation (TTA), can be [None, 'lr', 'd4'], default is None, 'lr' is flip TTA, 'd4' is multiscale TTA

"--rgb" denotes whether to output masks in RGB format

1️⃣LoveDA (Online Testing)
