首先，附上geometric官网链接：geometric官网
如果你不想看geometric官网，那么往下看：
首先进入自己的环境，按顺序输入如下五行（当然需要替换了）：
1
2
3
4
5
pip install torch-scatter==latest+${CUDA} -f https://pytorch-geometric.com/whl/torch-${TORCH}.html
pip install torch-sparse==latest+${CUDA} -f https://pytorch-geometric.com/whl/torch-${TORCH}.html
pip install torch-cluster==latest+${CUDA} -f https://pytorch-geometric.com/whl/torch-${TORCH}.html
pip install torch-spline-conv==latest+${CUDA} -f https://pytorch-geometric.com/whl/torch-${TORCH}.html
pip install torch-geometric
然后即可安装成功。
即，如果你是CUDA10.2，torch1.5.0，则输入：
1
2
3

pip install torch-scatter==latest+cu102 -f https://pytorch-geometric.com/whl/torch-1.5.0.html
pip install torch-sparse==latest+cu102 -f https://pytorch-geometric.com/whl/torch-1.5.0.html
pip install torch-cluster==latest+cu102 -f https://pytorch-geometric.com/whl/torch-1.5.0.html
pip install torch-spline-conv==latest+cu102 -f https://pytorch-geometric.com/whl/torch-1.5.0.html
pip install torch-geometric
