我一直在做名为网络分析入门(Pt1)的Datacamp课程,并且有一个以Graph / DiGraph形式出现的测试网络。
在他们网站上的交互式python shell
中,我可以键入T.edges()
,T.nodes()
等。但是我不知道如何在本地计算机上加载相同的网络。
数据以.p扩展名提供。点击https://mega.nz/#!hs4RhbjC!ukDcb6pDiJSEoAGy-WiosfcMgP62qiQgAAAAAAAAAAA)访问文件。
import networkx as nx
dg = pickle.load(open('../data/tw.p'))
print (dg.edges())
它读取错误
Traceback (most recent call last):
File "C:\Code\DataCamp-master\21-network-analysis-in-python-(part-1)\01-introduction-to-networks\02-queries-on-a-graph.py", line 22, in <module>
dg = pickle.load(open('../data/tw.p'))
File "C:\ProgramData\Anaconda3\lib\encodings\cp1251.py", line 23, in decode
return codecs.charmap_decode(input,self.errors,decoding_table)[0]
UnicodeDecodeError: 'charmap' codec can't decode byte 0x98 in position 4933: character maps to <undefined>
@
T = nx.read_gpickle('../folder/tw.p')
当我尝试通过nx.read_gpickle时,我得到了:
Traceback (most recent call last):
File "C:\Code\DataCamp-master\21-network-analysis-in-python-(part-1)\01-introduction-to-networks\02-queries-on-a-graph.py", line 21, in <module>
print (T.nodes())
File "C:\ProgramData\Anaconda3\lib\site-packages\networkx\classes\graph.py", line 719, in nodes
nodes = NodeView(self)
File "C:\ProgramData\Anaconda3\lib\site-packages\networkx\classes\reportviews.py", line 168, in __init__
self._nodes = graph._node
AttributeError: 'DiGraph' object has no attribute '_node'
下面显示的是它的外观,我不知道如何使它像这样:
Directed Graph from the provided file.
The Twitter network has been loaded as `T`.
在[1] type(T)
networkx.classes.digraph.DiGraph
T.nodes(data=True)[:10]
[(1, {'category': 'I', 'occupation': 'scientist'}),
(3, {'category': 'P', 'occupation': 'politician'}),
(4, {'category': 'D', 'occupation': 'celebrity'}),
(5, {'category': 'I', 'occupation': 'politician'}),
(6, {'category': 'D', 'occupation': 'politician'}),
(7, {'category': 'D', 'occupation': 'scientist'}),
(8, {'category': 'I', 'occupation': 'celebrity'}),
(9, {'category': 'D', 'occupation': 'celebrity'}),
(10, {'category': 'I', 'occupation': 'celebrity'}),
(11, {'category': 'I', 'occupation': 'celebrity'})]
我似乎不明白如何将.p文件转换为Graph的基本思想。
答案 0 :(得分:0)
我也遇到了在本地系统上加载datacamp课程中使用的.p文件的相同问题。
$pip freeze | grep networkx
在datacamp练习脚本中使用以上命令,我注意到他们在课程中使用的网络版本为 networkx == 1.1 。恢复到此版本可帮助我解决您遇到的以下错误。
AttributeError: 'DiGraph' object has no attribute '_node'.
希望这会有所帮助。 谢谢
