'Economy Gains 227,000 Jobs in January Under President Trump - Breitbart,川沙公路,The U. S. economy gained 227, 000 jobs in January according to statistics released by the Labor Department on Friday, while unemployment ticked up slightly to 4. 8 percent. [Wages also increased 2. 5 percent compared to January 2016, rising six cents in December.  The economy added 157, 000 jobs in December and unemployment stood at 4. 7 percent. A number of companies announced before Trump’s inauguration they planned to expand in the U. S. not overseas, and hire American workers. These included Ford, SAP SE, Amazon. com, Lockheed Martin, GM, Bayer AG, Walmart, and many more. Employers have also found themselves managing a tighter employment market, according to the New York Times: Regardless of government estimates, however, employers across sectors and across the nation have increasingly complained about the difficulty of finding workers, a competition that kept the increase in the average hourly wage ahead of a 1. 6 percent price inflation rate. “We’re still continuing to see wage pressure as the candidate market continues to shrink,” said Amy Glaser, senior vice president of Adecco Staffing USA, which has 300 branch offices. In addition to the omnipresent hunger for engineers, Ms. Glaser said there is a demand for those with   trade skills like welding that fell into disuse during the recession, as well as   warehouse and light assembly workers. “Employers are getting very creative,” said Ms. Glaser, whose office is in Lexington, Ky. “We’re seeing   bonuses. They have added sabbaticals to their packages, increases to stock options, free child care on site and free meals. Anything to get a competitive edge. ” After Election Day, many companies, especially small businesses, responded with soaring optimism. During his inaugural address, Trump said: “We will follow two simple rules: Buy American and hire American. ”'

已经可以了。

可以看到你的english.pickle文件所在路径为C:\Users\Administrator\AppData\Roaming\nltk_data\tokenizers\punkt\punkt

这里多叠加了一个punkt文件夹，是你解压文件造成的，你需要改变文件的深度。

让englisth.pickle文件位于C:\Users\Administrator\AppData\Roaming\nltk_data\tokenizers\punkt下面

我这边是可以直接运行的。

你看下你的文件设置哪里和我不一样

from nltk.tokenize import word_tokenize

string="Economy Gains 227,000 Jobs in January Under President Trump - Breitbart"

word_tokenize(string)

看到有english.pickle文件

你需要重新下载punkt的资源包

谢谢老师，问题已经解决了！

你可以截下图吗？两者的具体内容应该没有什么区别

from sklearn.datasets import make_moons

feature,target = make_moons(n_samples=100,noise=0.05)

from matplotlib import pyplot

from pandas import DataFrame

df = DataFrame(dict(x=feature[:,0],y=feature[:,1],label=target))

colors={0:'red',1:'blue'}

fig,ax= pyplot.subplots()

grouped = df.groupby('label')

for key,group in grouped:

group.plot(ax=ax,kind='scatter',x='x',y='y',label=key,color=colors[key])

pyplot.show()

from sklearn.datasets import make_circles

feature,target = make_circles(n_samples=100,noise=0.05)

from matplotlib import pyplot

from pandas import DataFrame

df = DataFrame(dict(x=feature[:,0],y=feature[:,1],label=target))

colors={0:'green',1:'blue'}

fig,ax= pyplot.subplots()

grouped = df.groupby('label')

for key,group in grouped:

group.plot(ax=ax,kind='scatter',x='x',y='y',label=key,color=colors[key])

pyplot.show()

有make_moons 和 make_cricles ,他们最终展示的图形样式不一样。但是实际应用中是用来做什么的？

就假设有5个字段吧，找不回来了。 x是个数据框的意思是什么呢

问：set this to C:\nltk_data (Windows)
老师，请问这个是什么意思？

答：也就是说，你应该在下载过程中，根据自己电脑的操作系统情况比如你是windows，将下载路径指定为他说的C:\nltk_data

如果你的nltk.download()没有严格按照要求执行，后面的语句wnl.lemmatize('countries')运行时就会提示没有资源，就像你发到帖子上的错误提示那样：Resource wordnet not found.

通过你帖子里的第一章图片来看，你应该是语料库没有下载成功，所以导致后面用的时候出现错误提示
