AttributeError:“Graph”对象没有属性“node”

Question

我有下面的python代码来构建knn-graph，但是我有一个错误：AttributeError:“graph”对象没有属性“node”。看来nx.图形（）没有节点属性，但我不知道应该用它替换什么。在

import networkx as nx
def knn_graph(df, k, verbose=False):
    points = [p[1:] for p in df.itertuples()]
    g = nx.Graph()
    if verbose: print ("Building kNN graph (k = %d)" % (k))
    iterpoints = tqdm(enumerate(points), total=len(points)) if verbose else enumerate(points)
    for i, p in iterpoints:
        distances = map(lambda x: euclidean_distance(p, x), points)
        closests = np.argsort(distances)[1:k+1] # second trough kth closest
        for c in closests:
            g.add_edge(i, c, weight=distances[c])
        g.node[i]['pos'] = p
    return g

Answer 1

如果使用NetworkX 2.4，请使用G.nodes[]而不是G.node[]。因为后一个属性已被弃用。请参见（https://networkx.github.io/documentation/stable/release/release_2.4.html#deprecations）。在
