WebIn this tutorial, we will look at PyTorch Geometric as part of the PyTorch family. Similar to PyTorch Lightning, PyTorch Geometric is not installed by default on GoogleColab (and actually also not in our dl2024 environment due to many dependencies that would be unnecessary for the practicals). Hence, let’s import and/or install it below: [8]: WebPytorch_geometric需要跟torch-scatter和torch-sparse一起使用。在安装torch-scatter时可能会遇到编译报错的情况. 问题1: 编译报错，gcc版本过低。 centos默认gcc是4.8.5，不支持c++ 14，因此需要升级gcc，版本4.9以上就可以了。 问题2：编译报错：fatal error: cusolverDn.h: No such file or ...
