Question

我正在尝试在运行Ubuntu 14.04的计算机上使用pydna模块，当我尝试导入它时出现以下错误：

  File "<stdin>", line 1, in <module>
  File "/usr/local/lib/python2.7/dist-packages/pydna/__init__.py", line 97, in <module>
    from pydna.amplify                                  import Anneal
  File "/usr/local/lib/python2.7/dist-packages/pydna/amplify.py", line 32, in <module>
    from pydna.dsdna                    import rc
  File "/usr/local/lib/python2.7/dist-packages/pydna/dsdna.py", line 63, in <module>
    from IPython.display import Markdown as display
ImportError: cannot import name Markdown

有没有人找到解决这个问题的方法？我曾尝试重新安装IPython和pydna。 dsdna.py中的违规块如下：（第58-63行）

try:
    import IPython
except ImportError:
    def display(item): return item
else:
    from IPython.display import Markdown as display

非常感谢任何帮助！

（Python 2.7.6）

我安装了IPython 4.1.1，它对我有用（见下文）。你有哪个版本？另外，你安装了哪个pydna版本？

这可能是由于版本太旧的IPython，最近IPython被拆分为IPython和Jupyter，这导致一些代码中断。

Python错误：IPython.display导入Markdown作为显示
