NetworkX storage of graph info

问题 I'm recently working on constructing social network graphs using networkX. I'm able to visualize and manipulate the graph at small scale. Howerver Im interested in knowing where networkX stores this graph info. This is because, I'm having a large collection of users for whom I need to construct graph and use the graph info for some suggestions. So I would like to know if I could store and access the graph. 回答1: NetworkX stores graph data in Python objects instantiated from one of several

问题 I am trying to use the pyvis library to show py network using the following code: import numpy as np import networkx as nx from pyvis.network import Network adjacency_matrix = [[0.5, 0.2, 0.3, 0], [0.1, 0.1, 0, 0.8], [0.3, 0, 0.4, 0.3], [0, 0.2, 0.2, 0.6]] A = np.array(adjacency_matrix) G = nx.from_numpy_matrix(A, create_using=nx.MultiDiGraph) G2 = Network() G2.from_nx(G) G2.show('network_map.html') I am not getting any error but this code is supposed to open a browser with the html file

2021年的第一盆冷水：有人说别太把图神经网络当回事儿

图神经网络（GNN）是目前热门的研究方向，但我们是否应把注意力过多地放在这上面？数据科学家 Matt Ranger 从模型的本质、性能基准测试、实践应用等方面陈述了自己的观点。 选自 http:// singlelunch.com ，作者：Matt Ranger，机器之心编译，机器之心编辑部。 图神经网络（GNN）是机器学习中最热门的领域之一，在过去短短数月内就有多篇优秀的综述论文。但数据科学家 Matt Ranger 对 GNN 却并不感冒。他认为这方面的研究会取得进展，但其他研究方向或许更重要。 博客链接： https://www. singlelunch.com/2020/12 /28/why-im-lukewarm-on-graph-neural-networks/ 机器之心对这篇博客进行了编译整理，以下是博客内容。 模型的关键是压缩 图经常被认为是一种「非欧几里得」数据类型，但实际上并不是。正则图（regular graph）只是研究邻接矩阵的另一种方式： 如上图所示，充满实数的矩阵却被称为「非欧几里得」，这很奇怪。 其实这是出于实际原因。大多数图都相当稀疏，因此矩阵中会包含很多 0。从这个角度看，非零数值非常重要，这让问题接近于（计算上很难的）离散数学，而不是（容易的）连续、梯度友好的数学。 有了全矩阵，情况会变得容易 如果不考虑物理领域的内容，并假设存在全邻接矩阵

Separate edge arrows in python/networkx directed graph

问题 I would like to obtain something similar to this: using the python library networkx. I can generate a similar directed graph using the following code: import matplotlib.pyplot as plt import networkx as nx G = nx.DiGraph() G.add_edge('1','2') G.add_edge('1','3') G.add_edge('3','2') G.add_edge('3','4') G.add_edge('4','3') nx.draw(G, node_color='w', edgecolors='k', width=2.0, with_labels=True) plt.show() which produces: However, the arrows between the nodes 3 and 4 are superimposed, and it just
