考虑在大小为N-by-M的网格上排列的一组点.我正在尝试构建邻接矩阵,以便连接相邻点.

例如,在带有图形的3x3网格中:

1-2-3
| | |
4-5-6
| | |
7-8-9

我们应该有相应的邻接矩阵:

+---+------------------------------------------------------+
|   |   1     2     3     4     5     6     7     8     9  |
+---+------------------------------------------------------+
| 1 |   0     1     0     1     0     0     0     0     0  |
| 2 |   1     0     1     0     1     0     0     0     0  |
| 3 |   0     1     0     0     0     1     0     0     0  |
| 4 |   1     0     0     0     1     0     1     0     0  |
| 5 …

我现在一直在与这个问题作斗争,我知道这很简单 - 但我对Python或NetworkX没什么经验.我的问题非常简单,我试图绘制一个大型数据集(大约200行/列)的矩阵,看起来像这样.第一行和第一列是相同的.

  A,B,C,D,E,F,G,H,I,J,K
A,0,1,1,0,1,1,1,1,0,1,0
B,1,0,0,0,1,1,1,1,0,1,0
C,1,0,0,0,1,1,1,1,0,1,0

它只是一个显示人们如何连接的矩阵,我想要的只是导入和绘制这个csv文件,并在NetworkX中使用它的相应标签.

我有这个文件(people.csv),并在这里查看以前的答案,似乎最好的方法是将数据放在一个numpy数组中.

这似乎有一个问题:

import numpy as np
import networkx as nx
import matplotlib.pyplot as plt
from numpy import genfromtxt
import numpy as np

mydata = genfromtxt('mouse.csv', delimiter=',')

我得到以下输出:

File "/System/Library/Frameworks/Python.framework/Versions/2.7/Extras/lib/python/numpy/lib/npyio.py", line 1272, in genfromtxt
  fhd = iter(np.lib._datasource.open(fname, 'rbU'))
File "/System/Library/Frameworks/Python.framework/Versions/2.7/Extras/lib/python/numpy/lib/_datasource.py", line 145, in open
  return ds.open(path, mode)
