As the chaincode container will issue npm install upon instantiation, I added a new container called npmregistry in the docker-composer.yml so that it is provisioned alongside the rest of the Fabric containers and belongs to the same docker network (composer_default). Note I'm using the fabric-tools downloaded from https://hyperledger.github.io/composer/latest/installing/development-tools.html ) npmregistry: container_name: npmregistry image: verdaccio

How can two joinFieldNames be specified? This is the scripted(post processing) version: Create edge Expands from (select from MC where sample=1 and mkey=6) to (select from Event where sample=1 and mcl=6) . This works, but is not suitable for production. Can anyone help? 回答1: you can simply add 2 joinFieldName(s) like { "edge": { "class": "Conn", "joinFieldName": "b1", "lookup": "A.a1", "joinFieldName":

I used the following code to create the graph and add weights, but I'm not sure how to tackle reassigning weights based on count: g = nx.MultiDiGraph() df = pd.read_csv('G:\cluster_centroids.csv', delimiter=',') df['pos'] = list(zip(df.longitude,df.latitude)) dict_pos = dict(zip(df.cluster_label,df.pos)) #print dict_pos for row in csv.reader(open('G:\edges.csv', 'r'

可以将文章内容翻译成中文,广告屏蔽插件可能会导致该功能失效(如失效，请关闭广告屏蔽插件后再试): 问题: I have a NetworkX graph. I would like to know how to do edge contraction between multiple nodes. For example, if I wanted to contract X, Y and Z: _ node A _ _/ | \_ node X --- node Y --- node Z Would become node A | node XYZ (or whatever X/Y/Z) Graph creation is not the problem. It works. I want to reduce the graph by merging nodes that have the same "meanings": nodes that I call "end lvl" (node name length is equal to 7) and that are linked together. I have found the condensation function in NetworkX so I tried to use it: # edge contraction

I would like to control the line solid_capstyle and solid_joinstyle , which are (matplotlib) Line2D properties. >>> import networkx as nx >>> import matplotlib.pyplot as plt >>> G = nx.dodecahedral_graph() >>> edges = nx.draw_networkx_edges(G, pos=nx.spring_layout(G), width=7) >>> plt.show() In the example above, there are 'gaps' between the edges which I'd like to hide by controlling the
