zsh：command not find:conda 的详细解决办

open ~/.zshrc

export PATH=/anaconda/bin:$PATH
source ~/.bash_profile

直接

pip install dgl

3.安装pyg

知乎的这个 改了官网的一个下划线

pip install torch_scatter==latest+cpu -f https://pytorch-geometric.com/whl/torch-1.5.0.html
pip install torch_sparse==latest+cpu -f https://pytorch-geometric.com/whl/torch-1.5.0.html
pip install torch_cluster==latest+cpu -f https://pytorch-geometric.com/whl/torch-1.5.0.html
pip install torch_spline-conv==latest+cpu -f https://pytorch-geometric.com/whl/torch-1.5.0.html
pip install torch-geometric
