networkx如何导入以下文本数据，权重显示第三列（日期和数字）？

求问如何修改使得边权重可以显示第三列的内容？

text.txt部分内容如下：
| #from | in | weight |
| 0 | 1 | 20210101,0.25 |
| 0 | 2 | 20210103,0,5 |
| 1 | 0 | 20210201,0.3 |
| 1 | 2 | 20210202,0.4 |
| 2 | 1 | 20210202,0.6 |

代码如下：

import networkx as nx
import numpy as np
import matplotlib.pyplot as plt
import pylab
 
g = nx.read_edgelist('./test.txt', nodetype=int,
    data=(('weight',float),), create_using=nx.DiGraph())
 
print(g.edges(data=True))
 
val_map = {'1':"red",   # 点颜色
    '0': "green"}
 
values = [val_map.get(node, 0.25) for node in g.nodes()]
edge_labels=dict([((u,v,),d['weight'])
                 for u,v,d in g.edges(data=True)])
 
red_edges = [(1,2),(0,2)]
edge_colors = ['black' if not edge in red_edges else 'red' for edge in g.edges()]
 
pos=nx.spring_layout(g)
nx.draw_networkx_labels(g, pos)   # 显示点中字母
nx.draw_networkx_edge_labels(g,pos,edge_labels=edge_labels)   # 显示边权重
nx.draw(g,pos, node_color = values, node_size=1500,edge_color=edge_colors,edge_cmap=plt.cm.Reds)
pylab.show()
