Answer 1

要使用该库，需要先安装它。可以从official site安装它。

在Ubuntu中可以通过apt-get：

获取它

sudo apt-get install python-matplotlib

在Windows中，对于标准Python安装，请使用pip安装matplotlib：

python -m pip install -U pip setuptools
python -m pip install matplotlib

Answer 2

您没有正确安装你应该像这样通过pip安装它 python -m pip install -u pip setuptools python -m pip安装matplotlib

（此方法仅在Windows中有效）
