手动安装torch_geometric版本2.0.4

• 在文档界面找到对应版本 https://readthedocs.org/projects/pytorch-geometric/versions/
• 选择对应cuda版本11.3，pytorch1.11.0，推荐使用pip命令
  
• 可以先手动安装上述库，在以下链接查看注意torch是1.11.0，cuda113https://pytorch-geometric.com/whl/torch-1.11.0%2Bcu113.html

pip install --no-index torch-scatter -f https://pytorch-geometric.com/whl/torch-1.11.0+cu113.html
pip install --no-index torch-sparse -f https://pytorch-geometric.com/whl/torch-1.11.0+cu113.html
pip install --no-index torch-cluster -f https://pytorch-geometric.com/whl/torch-1.11.0+cu113.html
pip install --no-index torch-spline-conv -f https://pytorch-geometric.com/whl/torch-1.11.0+cu113.html
pip install --no-index pyg_lib -f https://pytorch-geometric.com/whl/torch-1.11.0+cu113.html

• 指定版本安装 pip install torch-geometric==2.0.4 -f https://data.pyg.org/whl/torch-1.11.0+cu113.html

• 记录一些玄学BUG
• 测试conda安装方法显示pyg，不推荐

conda search pyg -c pyg
conda install pyg=2.0.4=py38_torch_1.11.0_cu113 -c pyg

• 报错缺少库 version `GLIBCXX_3.4.29’ not found
  strings /usr/lib/x86_64-linux-gnu/libstdc++.so.6 | grep GLIBCXX 查看只到3.24.8
  知乎答案降低scipy版本，从scipy 1.5.1到scipy 1.3.1，看见底下评论把conda库加入bashrc也是可以的export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:~/anaconda3/lib

ImportError: /lib/x86_64-linux-gnu/libstdc++.so.6: version `GLIBCXX_3.4.29' not found (required by .conda/envs/torch/lib/python3.8/site-packages/scipy/spatial/_ckdtree.cpython-38-x86_64-linux-gnu.so)
看起来似乎是scipy的问题

• impor torch显示unknown location，重新安装torch显示invalid requirement，怀疑是网络问题，手动下载指定版本再安装

ImportError: cannot import name 'Tensor' from 'torch' (unknown location)
pip install torch1.11.0+cu113 torchvision0.12.0+cu113 torchaudio==0.11.0 --extra-index-url https://download.pytorch.org/whl/cu113

pip install torch-1.11.0+cu113-cp38-cp38-linux_x86_64.whl

• 装好了想再重新安装，显示ERROR: torch-1.11.0+cu113-cp38-cp38-linux_x86_64.whl is not a supported wheel on this platform.，重新进入环境就行了
• conda install python==3.8.18更换python解释器3.8.18警告：RuntimeWarning: scipy._lib.messagestream.MessageStream size changedhttps://blog.csdn.net/qq_43710864/article/details/133916131
