GDB设置断点后,我不确定为什么不能按预期工作:

这是运行后我收到的错误我有这个问题:

Traceback (most recent call last):

这是prop.test函数:

baby.prop.test = function (x, n, p, conf.level = 0.95) {
  # ...
  return(prop.test(x,n,p,conf.level))
  #baby.prop.test$statistic
}
# test case
baby.prop = baby.prop.test(72, 100, .7, conf.level=.99)
stopifnot(isTRUE(all.equal(as.numeric(baby.prop$statistic), .43643578)))
stopifnot(isTRUE(all.equal(as.numeric(baby.prop$p.value), .66252058)))

这是错误:

Error in match.arg(alternative) : 
  'arg' must be NULL or a character vector

知道什么是错的吗？

我正在遵循 NLTK教程，在 Python 交互式 shell 中遇到此错误，而本书显示了另一个结果。知道如何解决这个问题吗？

>>> import nltk
>>> nltk.corpus.gutenberg.files()
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
AttributeError: 'PlaintextCorpusReader' object has no attribute 'files'

我不知道为什么我不能将其写入document文件：

document=['', 'feeling frisky cool cat hits join us', 'askjoe app add music videos free today saintkittsandnevis', 'give dog flea bath midnight greeeeat smells like dawn', 'cat finds flash drive spent weeks looking', 'downside cat dude means can recognize nice smell pee second', 'louis pine apple make life brighter like star please follow me', 'gonna need nice cup coffee morning', 'gonna need nice cup coffee morning', 'iphone gives warning dies smh']

这是写入文件的代码：

with open("cleaned_tweet.txt", "w") as cleaned_tweet_file:
    cleaned_tweet_file.write(document) …

我该如何解决这个问题？

/tmp/hadoop-yarn/staging/ubuntu/.staging/job_1450038005671_0025/job.jar: Under replicated BP-938294433-10.0.1.190-1450037861153:blk_1073744219_3398. Target Replicas is 10 but found 3 replica(s).

当我hadoop fsck /在主节点中运行时,我得到了这个.我假设我应该.xml在conf或类似的东西中更改文件我只是不知道要更改哪个文件.

请注意,dfs.replicationin hdfs-site.xml已设置为3. dfs.replication.max我的hdfs-site.xml文件中没有.

我安装了plotly usingpip inOS X`:

Monas-MacBook-Pro:~ mona$ pip install plotly
Requirement already satisfied (use --upgrade to upgrade): plotly in ./anaconda/lib/python2.7/site-packages
Requirement already satisfied (use --upgrade to upgrade): pytz in ./anaconda/lib/python2.7/site-packages (from plotly)

当我尝试使用它时,julia我收到以下错误:

julia> using Plotly
ERROR: ArgumentError: Plotly not found in path
 in require at /Applications/Julia-0.4.3.app/Contents/Resources/julia/lib/julia/sys.dylib

我怎样才能解决这个问题？

你知道我为什么在第二行输出中印有"1"吗？

def word_map(string):
    dict = {}
    for word in string.split():
        word = filter(str.isalnum, word).lower()
        word = word.split()
        if word in dict:
            dict[word] +=1
        else:
            dict[word] = 1
    return dict

dict = word_map("This is a string , this is another string too")
for k in dict:
    print k, dict[k]

结果是:

a 1
 1
string 2
this 2
is 2
too 1
another 1

Process finished with exit code 0

我正在为 renderdoc 使用 CMake GUI，我收到了这些消息。我应该如何修复它们？

在 Firefox 中浏览时，我可以看到http://www.chicagotribune.com/ct-florida-school-shooter-nikolas-cruz-20180217-story.html 。但是，newspaper3k给了我这个错误：

Article download() failed with HTTPSConnectionPool(host='www.chicagotribune.com', port=443): Read timed out. (read timeout=7) on URL http://www.chicagotribune.com/ct-florida-school-shooter-nikolas-cruz-20180217-story.html

我的代码是：

from newspaper import Article
from newspaper import Config

user_agent = 'Mozilla/5.0 (Macintosh; Intel Mac OS X 10.15; rv:78.0) Gecko/20100101 Firefox/78.0'
config = Config()

config.browser_user_agent = user_agent

url = "https://www.chicagotribune.com/nation-world/ct-florida-school-shooter-nikolas-cruz-20180217-story.html"

page = Article(url, config=config)


page.download()
page.parse()
print(page.text)

我认为像“renewIPAddress()”之类的东西可能会有所帮助，但我不确定如何准确地将其适合此代码。/sf/answers/3534773791/
