我试图呈现在IPython的笔记本来复杂的数学横跨在来到这个答案,这IPython的笔记本展示了丰富的显示系统(向下滚动至底部是最后一个例子),其中都提到一个的可用性%%latex细胞.但是,在尝试制作乳胶细胞时出现以下错误,

错误:%%latex未找到单元魔术功能.

我正在运行0.13.2版,我遗失了什么？我需要以某种方式导入这个神奇的功能吗？

所以 - ROOT社区中的优秀人员产生了以下魔力:

# This is for intercepting the output of ROOT
# In a cell, put %%rootprint so that the output that would normally be
# sent directly to the stdout will instead be displayed in the cell.
# It must be the first element in the cell.
import tempfile
import ROOT
from IPython.core.magic import (Magics, magics_class, cell_magic)

@magics_class
class RootMagics(Magics):
    """Magics related to Root.

    %%rootprint  - Capture Root stdout output and show in result cell
    """

我在mavericks osx上安装了anaconda.当我尝试从启动器应用程序安装ipython笔记本时 - 它显示应用程序正在安装的消息,但之后没有任何反应.启动器中的链接也不起作用,我可以轻松地从终端启动ipython笔记本.所以我觉得启动器本身有问题.

我该如何解决？

我一直在本地托管笔记本上工作一段时间没有任何问题.但是,我最近重新打开笔记本,发现我的所有单元格都重叠,如下图所示:

如果我再次上下移动细胞,它们似乎正确地重新对齐.我能想到的唯一变化可能是因为我最近更新了我的anaconda包.控制台的所有输出对我来说都是正常的.

知道可能导致这种情况的原因吗？

系统信息:

• Python 2.7.8 :: Anaconda 2.1.0(x86_64)

我有一个函数createWidgets,其目的是获取字符串列表并为每个字符串创建一个容器列表 - > 1容器=一个文本框和复选框.然后将每个容器放入大容器中.

我要做的是在容器上附加一个按钮,on_click将获取所有"True"并放入所有修改过的字符串并将它们放入数据框中

    widgelist = e.options
    txtBox_type = 'text_widget' # Define if Area box o regular txtbox
    bigContainer = createWidgets(widgelist, txtBox_type)

    Function
    def createWidgets(widgelist, txtBox_type):

        #containerList = []
        i = 0

        for k in widgelist:
        ## Build Container widgets

           chBox_Widget = widgets.CheckboxWidget(description = str(i),value = False,)
           if txtBox_type == 'textA_widget': # Check wether txtBox should be an area txt box or not.
               txt_Widget = widgets.TextareaWidget( description = str(i), value = k)
           else:
               txt_Widget = widgets.TextWidget( description = str(i), …

我有一个表示事件日志的日期时间对象列表:

 [datetime.datetime(2014, 12, 16, 0, 18, 12),
  datetime.datetime(2014, 12, 16, 0, 18, 27),
  datetime.datetime(2014, 12, 16, 0, 18, 27),
  datetime.datetime(2014, 12, 16, 0, 19, 9),
  datetime.datetime(2014, 12, 16, 0, 19, 39),
  datetime.datetime(2014, 12, 16, 0, 19, 49),
  datetime.datetime(2014, 12, 16, 0, 20, 2),
  datetime.datetime(2014, 12, 16, 0, 20, 19),
  datetime.datetime(2014, 12, 16, 0, 20, 47),
  ...
  datetime.datetime(2014, 12, 16, 6, 23, 43),
  datetime.datetime(2014, 12, 16, 6, 25, 45)]

如何创建每秒事件数量的情节？例如,价值应该是:

• 1表示datetime.datetime(2014,12,16,0,18,12)
• 0表示datetime.datetime(2014,12,16,0,18,13) - datetime.datetime(2014,12,16,0,18,26)
• 2表示datetime.datetime(2014,12,16,0,18,27)
• 等等

我试过这样的事情:

pd.Series([1 for _ in …

我正在使用iPython笔记本来测试交互功能.几个月前,以下示例(从这里开始)对我来说很好.但是,如果我现在运行它,它会绘制可能组合的所有图像.我不知道这是否是重复的,但这个并没有帮助.

%matplotlib inline

import numpy as np
import matplotlib.pyplot as plt
import matplotlib as mpl

# mpl.rcParams['figure.max_open_warning'] = 1

def plot(amplitude, color):

    fig, ax = plt.subplots(figsize=(4, 3),
                           subplot_kw={'axisbg':'#EEEEEE',
                                       'axisbelow':True})

    ax.grid(color='w', linewidth=2, linestyle='solid')
    x = np.linspace(0, 10, 1000)
    ax.plot(x, amplitude * np.sin(x), color=color,
            lw=5, alpha=0.4)
    ax.set_xlim(0, 10)
    ax.set_ylim(-1.1, 1.1)

    return fig

from ipywidgets import StaticInteract, RangeWidget, RadioWidget

StaticInteract(plot,
               amplitude=RangeWidget(0.1, 1.0, 0.1),
               color=RadioWidget(['blue', 'green', 'red']))

这是输出: 你能帮助我吗？

我有一个neo4j图,我想在一个带有网络x的ipython笔记本中绘制整个图形.我该怎么做呢？

像这样的东西？

g1 = nx.neo4j_graph
nx.draw(g1)
plt.show()

我安装了IPython 4.0.1.我无法弄清楚以下错误的原因 -

>>> from IPython.html import widgets
>>> k = widgets.Box
Traceback (most recent call last):
  File "C:\Python34\lib\site-packages\IPython\utils\shimmodule.py", line 90, in __getattr__
    return import_item(name)
  File "C:\Python34\lib\site-packages\IPython\utils\importstring.py", line 31, in import_item
    module = __import__(package, fromlist=[obj])
ImportError: No module named 'ipywidgets'

During handling of the above exception, another exception occurred:

Traceback (most recent call last):
  File "<pyshell#8>", line 1, in <module>
    k = widgets.Box
  File "C:\Python34\lib\site-packages\IPython\utils\shimmodule.py", line 92, in __getattr__
    raise AttributeError(key)
AttributeError: Box

我怎样才能解决这个问题？

我正在使用R ipython笔记本（相对R新手），并尝试使用“ bigrquery”从Google Big Query提取数据。有人告诉我这应该很简单，但是使用标准sql进行提取是行不通的。

这是我的代码：

require("bigrquery")

# Use your project ID here
project <- "project-id" # put your project ID here

standard_sql <- "SELECT year, month, day, weight_pounds FROM `publicdata.samples.natality` LIMIT 5"

legacy_sql <- "SELECT year, month, day, weight_pounds FROM [publicdata:samples.natality] LIMIT 5"

# doesn't work
standard_data <- query_exec(standard_sql, project = project, useLegacySql = FALSE)

# works
legacy_data <- query_exec(legacy_sql, project = project, useLegacySql = TRUE)

对于上面的标准sql，它返回以下错误：

Error: Invalid table name: `publicdata:samples.natality`
Traceback:

1. query_exec(standard_sql, project = project, useLegacySql …
