所有人的上帝之日。我正试图在木星+ IPython环境下,执行由Cirille的"IPython交互式计算--可视化烹饪“一书中的代码。
在我尝试之前,一切都很好:
from collections import OrderedDict
from IPython.display import (display, clear_output, YouTubeVideo)
from IPython.html.widgets import DropdownWidget如果我确实重新启动内核,则会出现以下消息:
/usr/local/lib/python3.4/dist-packages/IPython/html.py:14: ShimWarning: The `IPython.html` package has been deprecated. You should import from `notebook` instead. `IPython.html.widgets` has moved to `ipywidgets`.
"`IPython.html.widgets` has moved to `ipywidgets`.", ShimWarning)然后,我试图通过以下方式更改第三行(问题):
from ipywidgets import DropdownWidgets但朱庇特回答:ImportError: cannot import name 'DropdownWidget'
有人能帮帮我吗?
下一个是部分答案
好吧,在这个网页上我找到了ipywidgets安装对我的问题和问题的答案。
我试着做下一个例子,做得很好:
import numpy as np
url = "http://donnees.ville.montreal.qc.ca/dataset/f170fecc-18db-44bc-b4fe-5b0b6d2c7297/resource/ec12447d-6b2a-45d0-b0e7-fd69c382e368/download/2013.csv"
df = pd.read_csv(url, index_col='Date', parse_dates=True, dayfirst=True)
from ipywidgets import interact
@interact
def plot(n=(1, 30)):
pd.rolling_mean(df['Berri1'], n).dropna().plot()
plt.ylim(0, 8000)
plt.show()但是jupyter声称我必须这样做:jupyter nbextension enable --py --sys-prefix widgetsnbextension
我去了终点站,听从了我的建议,并回答说:
Configure an nbextension to be automatically loaded
Options
-------
Arguments that take values are actually convenience aliases to full
Configurables, whose aliases are listed on the help line. For more information
on full configurables, see '--help-all'.
--debug
set log level to logging.DEBUG (maximize logging output)
-y
Answer yes to any questions instead of prompting.
--generate-config
generate default config file
--section=<Unicode> (EnableNBExtensionApp.section)
Default: 'notebook'
Which config section to add the extension to. 'common' will affect all
pages.
To see all available configurables, use `--help-all`
[EnableNBExtensionApp] CRITICAL | Bad config encountered during initialization:
[EnableNBExtensionApp] CRITICAL | Unrecognized flag: '--py'看一下,在1中有这样的建议:jupyter nbextension enable --py widgetsnbextension,但是在控制台中建议使用jupyter nbextension enable --py --sys-prefix widgetsnbextension。请注意,有一点差别,但在这两种情况下出现相同的错误关于--py选项
在这一刻,这个问题得到了部分回答。

好吧,在网页上查找我在jupyter页面(jupyter)上找到的重新浏览过的笔记本,几乎可以很好地运行(除了一些例外,至少在第01章,我去尝试其他章节)。
