我正在研究使用 IBM Watson Machine Learning 预测户外设备购买的演示笔记本。我将笔记本复制到一个项目中并开始逐个单元格地运行。

一切都很顺利,除了当我进入第5.2 节:使用 Plotly 包的数据可视化示例

在本节中,首先安装一些库:

!pip install plotly --user 
!pip install cufflinks --user

接着 ...

import sys
import pandas
import plotly.plotly as py
from plotly.offline import download_plotlyjs, init_notebook_mode, plot, iplot
import cufflinks as cf
import plotly.graph_objs as go
init_notebook_mode(connected=True)
sys.path.append("".join([os.environ["HOME"]]))

这导致:

ImportError: No module named talib

所以我修改了 pip 命令并重新运行:

!pip install plotly --user --upgrade
!pip install cufflinks --user  --upgrade

当我重新运行绘图代码时,我得到:

ImportErrorTraceback (most recent call last)

      3 import plotly.plotly as py
      4 from plotly.offline import download_plotlyjs, init_notebook_mode, plot, iplot
----> 5 import cufflinks as cf
      6 import plotly.graph_objs as go
      7 init_notebook_mode(connected=True)

     10 
---> 11 from . import date_tools
     12 from . import utils
     13 from . import datagen

ImportError: cannot import name date_tools

更新:我尝试修复袖扣库版本:

Successfully installed cufflinks-0.8.2

使用不同版本的袖扣库时会出现您遇到的问题。

这应该修复 !pip install cufflinks==0.8.2 --user
