1) Environment requirements
- Python >= 3.7
- Pytorch >= 1.9.0
- CUDA >= 10.2
The following installation guide supposes python=3.7, pytorch=1.12.1, cuda=11.3, torch-scatter=2.0.9, and spconv-cu113==2.1.25. You may change them according to your system.
Create a conda virtual environment and activate it.
conda create -n gapro python=3.7
conda activate gapro
2) Install the dependencies
conda install pytorch==1.12.1 torchvision==0.13.1 cudatoolkit=11.3 -c pytorch
pip3 install spconv-cu113==2.1.25
pip3 install torch-scatter==2.0.9 -f https://data.pyg.org/whl/torch-1.12.1+cu113.html
pip3 install -r requirements.txt
3) Install Segmentator
git clone https://github.com/Karbo123/segmentator.git
cd segmentator/csrc
mkdir build && cd build
cmake .. \
-DCMAKE_PREFIX_PATH=`python -c 'import torch;print(torch.utils.cmake_prefix_path)'` \
-DPYTHON_INCLUDE_DIR=$(python -c "from distutils.sysconfig import get_python_inc; print(get_python_inc())") \
-DPYTHON_LIBRARY=$(python -c "import distutils.sysconfig as sysconfig; print(sysconfig.get_config_var('LIBDIR'))") \
-DCMAKE_INSTALL_PREFIX=`python -c 'from distutils.sysconfig import get_python_lib; print(get_python_lib())'`
make && make install
4) Install build requirement
sudo apt-get install libsparsehash-dev
5) Setup ISBNet
cd ./ISBNet/isbnet/pointnet2
python3 setup.py bdist_wheel
cd ./dist
pip3 install <.whl>
cd ../../../
python3 setup.py build_ext develop
6) Setup SPFormer
