Matplotlib Jupyter 5、Python 3.6和Latex,matplotlib,jupyter-notebook,python-3.6,Matplotlib,Jupyter Notebook,Python 3.6,我想用Jupyter笔记本记录我的研究成果。以前，我使用了一个带有Python2.7和Jupyter4的笔记本，没有任何问题。得益于Anaconda，我最近一直在尝试使用Jupyter 5和Python 3.6。但是，当我试图显示热图时，我收到一个错误使用简单折线图编辑 #--编码：utf-8-- %matplotlib内联 from future.builtins import * from future.utils import (viewitems, viewkeys, viewvalu
