<p>我正在使用matplotlib和python 3.4。
当我启动程序时,会显示以下警告消息:</p>
<blockquote>
<p>C:\Python34-32bits\lib\site-packages\matplotlib\cbook.py:123:
MatplotlibDeprecationWarning: The matplotlib.mpl module was deprecated
in version 1.3. Use <code>import matplotlib as mpl</code> instead.
warnings.warn(message, mplDeprecation, stacklevel=1)</p>
</blockquote>
<p>据我所知,我不使用mpl,而且我所有关于matplotlib的导入都是:</p>
<pre><code>import matplotlib.pyplot as plt
import matplotlib.animation as animation
</code></pre>
<p>我该怎么办?</p>
