问题描述
我正在尝试使用 news3k 从包含演讲的网页中提取演讲者姓名，但没有运气。根据包的文档，Wavenumbers = DFF.columns
#in fact this is a little more complicated but that's the spirit
Spectre = DFF.values.tolist()
#btw DFF is my pandas.dataframe containing spectrum with features = wavenumber
SS = StandardScaler(copy=True)
DFF = SS.fit_transform(DFF) #at this point I use SS for preprocessing before PCA
#I'm then trying to inverse SS and get back the 1rst spectrum of the dataset
D = SS.inverse_transform(DFF[0])
#However at this point DFF[0] and D are almost-exactly the same I'm sure because :
plt.plot(Wavenumbers,D)
plt.plot(Wavenumbers,DFF[0]) #the curves are the sames,and :
for i,j in enumerate(D) :
if j==DFF[0][i] : pass
else : print("{}".format(j-DFF[0][i] )) #return nothing bigger than 10e-16
似乎总是返回一个空列表。
使用文档 here 中的示例。
article.authors返回
In:
from newspaper import Article
url = 'http://fox13Now.com/2013/12/30/new-year-new-laws-obamacare-pot-guns-and-drones/'
article = Article(url)
article.download()
article.parse()
article.authors
而不是预期
Out: []
它也不适用于许多其他示例。
解决方法
在github 485上参考这个issue，newspaper3k在python3中好像坏了，如果你降级到python2，问题中提到了一个解决方法。
