我刚刚升级到最新版本的matplotlib
(1.5.1),但每次我导入matplotlib时都会收到以下消息:
/usr/local/lib/python2.7/dist-packages/matplotlib/font_manager.py:273: UserWarning: Matplotlib is building the font cache using fc-list. This may take a moment.
warnings.warn('Matplotlib is building the font cache using fc-list. This may take a moment.')
......这总是会停顿几秒钟。
这是预期行为吗?在打印消息之前也是这样吗?
