spconv==1.2.1配置：

1.安装cmake和boost
有sudo权限：
sudo snap install cmake --classic
cmake --version
sudo apt-get install libboost-all-dev
无sudo权限：
pip install cmake
pip install boost （或conda install）
  pip安装需要配置boost路径，将'-DCMAKE_CXX_FLAGS:STRING=-I /data/zhaoshenao/anaconda3/envs/DTS/include',添加到setup.py文件中的如下位置：
    def build_extension(self, ext):
        extdir = os.path.abspath(os.path.dirname(self.get_ext_fullpath(ext.name)))
        cmake_args = [# '-G "Visual Studio 15 2017 Win64"',
                      '-DCMAKE_PREFIX_PATH={}'.format(LIBTORCH_ROOT),
                      '-DPYBIND11_PYTHON_VERSION={}'.format(PYTHON_VERSION),
                      '-DSPCONV_BuildTests=OFF',
                      '-DPYTORCH_VERSION={}'.format(PYTORCH_VERSION_NUMBER)，
                      '-DCMAKE_CXX_FLAGS:STRING=-I /data/zhaoshenao/anaconda3/envs/DTS/include',
                      ] #  -arch=sm_61
