%matplotlib 内联：“NoneType”对象没有属性“is_interactive”

Question

我不知道为什么会这样。我该如何解决？

In [1]: %matplotlib inline

我得到了这个：

AttributeError: 'NoneType' object has no attribute 'is_interactive'

AttributeError: 'NoneType' object has no attribute 'is_interactive'

Answer 1

对我来说，

pip install jupyter_console

然后

ipython 控制台（'jupyter 控制台'推荐）

在 [1] 中：%matplotlib 内联

工作正常。

ipython 控制台 --matplotlib 内联

会引发错误：

无法识别的标志：'--matplotlib'
