导入袖扣为cf时，没有名为“ plotly.figure_factory”的模块

Question

我尝试import cufflinks as cf，但出现回溯错误：

Traceback (most recent call last):

  File "<ipython-input-22-fa10b240f3e4>", line 1, in <module>
    import cufflinks as cf

  File "/usr/local/lib/python3.6/dist-packages/cufflinks/__init__.py", line 15, in <module>
    from . import tools

  File "/usr/local/lib/python3.6/dist-packages/cufflinks/tools.py", line 6, in <module>
    import plotly.figure_factory as ff

ModuleNotFoundError: No module named 'plotly.figure_factory'

无论如何，我可以毫无问题地导入from plotly.tools import FigureFactory as FF。

有人可以帮忙吗？谢谢。
