Python 3.5 Jupyter 笔记本 ggplot "name error"

Question

在运行 Python 3.5.2 的 Jupyter Notebook 中使用 yHat 的 Python ggplot 库(请参阅下面的完整错误)时，出现 NameError: name 'unicode' is not Defined。具有以下导入语句:

 %matplotlib inline
from ggplot import * 

图表仍然呈现，但我想消除错误，或者隐藏它(如果它不会引起重大冲突)。

完整的错误如下。非常感谢:)

如果您安装了 anaconda，请尝试安装 code-forge 版本。我能够通过切换到 python 3.5 的版本来解决同样的问题

conda install -c conda-forge ggplot

希望有帮助
