WebThe coding examples are influenced by Pytorch geometric documentation. Getting Started. We will install the Pytorch package as pytorch_geometric is built upon it. !pip install -q torch. Then we will use the torch version to install torch-scatter and torch-sparse. After that, we will install pytorch_geometric’s latest release from GitHub. WebThe core of the GCN neural network model is a “graph convolution” layer. This layer is similar to a conventional dense layer, augmented by the graph adjacency matrix to use information about a node’s connections. This algorithm is discussed in more detail in “Knowing Your Neighbours: Machine Learning on Graphs”.
