为了更好地理解Graph的结构,我们可以使用类图和旅行图来进行说明。 1. 类图 以下是一个简单的类图,描述了图形的结构和相关功能。 Graph+add_node(node)+add_edge(node1, node2)+number_of_nodes()+number_of_edges() 在这个类图中,我们定义了一个Graph类,拥有添加节点、添加边、以及获取节点和边数量的相关方...
graph.node(name, label=None, **attrs): 添加一个节点 graph.edge(tail_name, head_name, label=None, _attributes=None, **attrs): 添加一条边 graph.edges(tail_head_iter):添加多个边 2.4 输出 graph.source: 输出graph的dot代码 graph.save(filename=None, directory=None, *, skip_existing=False)...
Deep Graph Library (DGL) 是一个 Python 包,用于在现有 DL 框架(目前支持 PyTorch、MXNet 和 TensorFlow)之上轻松实现图神
create_node(graph, default_datastore, context) 参数 展开表 名称说明 graph 必需 Graph 要将节点添加到的图对象。 default_datastore 必需 Union[AbstractAzureStorageDatastore, AzureDataLakeDatastore] 默认数据存储。 context 必需 <xref:azureml.pipeline.core._GraphContext> 图形上下文。 返回 ...
