jupyter lab 2.2.2 %pylab 内联弃用警告
jupyter lab 2.2.2 %pylab inline deprecation warnings
升级 matplotlib 和 jupyter、jupyter lab 后，内联魔术会产生弃用警告。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：
In C:\Python37\lib\site-packages\matplotlib\mpl-data\stylelib\_classic_test.mplstyle:
The text.latex.preview rcparam was deprecated in Matplotlib 3.3 and will be removed two minor releases later.
In C:\Python37\lib\site-packages\matplotlib\mpl-data\stylelib\_classic_test.mplstyle:
The mathtext.fallback_to_cm rcparam was deprecated in Matplotlib 3.3 and will be removed two minor releases later.
In C:\Python37\lib\site-packages\matplotlib\mpl-data\stylelib\_classic_test.mplstyle: Support for setting the 'mathtext.fallback_to_cm' rcParam is deprecated since 3.3 and will be removed two minor releases later; use 'mathtext.fallback : 'cm' instead.
In C:\Python37\lib\site-packages\matplotlib\mpl-data\stylelib\_classic_test.mplstyle:
The validate_bool_maybe_none function was deprecated in Matplotlib 3.3 and will be removed two minor releases later.

据我所知，Pylab 已被弃用。请参阅下面的 link（我能找到的最好的，Ipython 存储库上的一个线程）。我认为它破坏命名空间有很多问题。我看到的典型建议是将其替换为 %matplotlib inline.
