- Linux system, Windows, depending on
MMCVcan be installed - Python 3.6+, recommended 3.7
- PyTorch 1.10+ or higher, recommended 1.12.0
- CUDA 11.7 or higher, recommended 12.1
It is recommended to use Miniconda for installation. The following commands will create a virtual environment named bifa and install PyTorch. In the following installation steps, the default installed CUDA version is 12.1. If your CUDA version is not 12.1, please modify it according to the actual situation.
Note: If you are experienced with PyTorch and have already installed it, you can skip to the next section. Otherwise, you can follow the steps below.
Step 0: Install Miniconda.
Step 1: Create a virtual environment named bifa and activate it.
conda create -n bifa python=3.7
conda activate bifaStep 2: Install dependencies.
pip install -r requirements.txtNote: Use the following command to install mmcv
pip install mmcv-full==1.6.2 -f https://download.openmmlab.com/mmcv/dist/cu113/torch1.12/index.htmlYou can download or clone the BiFA repository.
git clone git@github.com:zmoka-zht/BiFA.git
cd BiFAWe provide the method of preparing the remote sensing change detection dataset used in the paper.
