Pandas 使用问题跟踪

pip install matplotlib --upgrade --user
I dont get any error but my program fails saying

Traceback (most recent call last):
  File "forest.py", line 22, in <module>
    matplotlib.style.use('ggplot')
AttributeError: 'module' object has no attribute 'style'
when I try to upgrade matplotlib without --user I get following error

$ pip install matplotlib --upgrade

    DEPRECATION: Uninstalling a distutils installed project (pyparsing) has been deprecated and will be removed in a future version. This is due to the fact that uninstalling a distutils project will only partially uninstall the project.
    Uninstalling pyparsing-2.0.1:

jupyter 安装错误


sudo pip install --upgrade ipython --ignore-installed six
