前一段时间我发现了以下website ,我从中复制了源代码并将其粘贴到我自己的 jupyter notebook 中。

%load_ext signature
%matplotlib inline

import requests
import helpers

import pandas as pd
import matplotlib as mpl
import matplotlib.pyplot as plt

from lxml import html
from datetime import datetime

# Set style and meta info.
mpl.style.use('ramiro')
url = 'https://en.wikipedia.org/wiki/Wikipedia:Database_reports/Pages_with_the_most_revisions'
end_date = '27 March 2015'
chartinfo = 'Author: Ramiro Gómez - ramiro.org • Data: ' + url.replace('https://', '')
infosize = 12

# Extract first wikitable from page
xpath = '//*[contains(@class, "wikitable")]'
tree = html.fromstring(requests.get(url).text)
table = tree.xpath(xpath)[0]
raw_html = html.tostring(table)

# Create dataframe from html table
df = pd.read_html(raw_html, header=0, index_col='Page')[0]
df.index = df.index.map(lambda x: x.replace('_', ' '))
df.head(10)

现在我重新发现了这个笔记本,想运行它。但是,它不起作用:

ImportError                               Traceback (most recent call last)

ImportError: No module named 'signature'

我不知道为什么缺少这个模块或者它实际上做了什么。

如何解决这个问题并让代码运行?

附加信息:

最佳答案

我也遇到过这个问题,摸索了一下,解决了。

请阅读关于%load_ext magic .显然 signature 是一个扩展,要使用它你需要先安装它。

现在的问题是你需要找到签名的代码。

我花了更长的时间才找到代码。本教程由 Ramiro Gómez 编写,我在 github and the script 上找到了他的网页。 .

要安装,您可以在 iPython shell 中使用 %install_ext 魔法。

关于python - Jupyter Notebook load_ext 签名,我们在Stack Overflow上找到一个类似的问题: https://stackoverflow.com/questions/35440072/
