【问题描述】：
升级matplotlib 和jupyter、jupyter lab 后，内联魔法会产生弃用警告。虽然这有点帮助，但这些警告会妨碍您。
当然可以关闭警告：
import warnings warnings.filterwarnings('ignore')
但这似乎不是最好的方法。
问题：如何在不关闭所有警告的情况下解决这些警告？
魔法：
%pylab inline
警告：

【问题讨论】：
-
_classic_test.mplstyle用于测试，见here。我想你可以简单地删除它。 -
删除后警告消失。不过，这似乎是一种解决方法。我尝试卸载
matplotlib，就像在 github 问题中一样，这没有帮助。
