DGL官方安装教程网址:Deep Graph Library
以下仅考虑Linux系统的情况。(在Windows上跑GNN是不是太身残志坚了)
以下对应可行的安装时间会对应附上。
注意:这里对应的cuda版本,一般情况下只要跟cudatoolkit对应上就行。

1. 安装
2022.8.3
我安装PyTorch用的Python3.8,命令是conda install pytorch==1.11.0 torchvision==0.12.0 torchaudio==0.11.0 cudatoolkit=10.2 -c pytorch
可以直接在DGL官网选择对应的情况,复制命令行进行安装:
注意在能够正常使用之前还需要安装psutil包,否则就会报如下错误:
Traceback (most recent call last):
File "", line 1, in <module>

from .dataloader import *
File "my_env/lib/python3.8/site-packages/dgl/dataloading/", line 12, in <module>
import psutil
ModuleNotFoundError: No module named 'psutil'
安装psutil(psutil的官方下载教程网站:psutil/ at master · giampaolo/psutil):pip install psutil
2. 检验安装效果
import dgl.data
dataset = dgl.data.CoraGraphDataset()
print('Number of categories:', dataset.num_classes)

(这个SciPy和numpy的版本警告我也没辙)
