好吧，经过一番折腾:将解释器更改为不同版本(Python 3.5.x)可以使这项工作成功。这让我想知道 IPython 是否是问题所在……确实是!!

问题是 IPython for Python 3.3.5 无法与 PyCharm 一起使用。 IPython 版本 5 由 PyCharm 安装，但不适用于 Python 3.3.5。

我使用“Conda uninstall”然后“Conda clean”删除了 IPython，并重新启动了控制台，然后它就像一个魅力......

本质上:1.退出Pycharm2. 删除 IPython - 使用“Conda remove/uninstall”，然后使用“conda clean”来完全删除它。3. 重新启动 Pycharm 并允许其重新导入所有“骨架”4. 重新启动控制台。
