>>>import matplotlib.pyplot as plt /usr/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.')
在第八讲中,导入这个模块出错
解决:
找到缓存目录 删除~/.cache/matplotlib下面的缓存 deleted ~/.cache/matplotlib/fontList.cache
但是，当我准备删的时候，再import matplotlib时时没有出错,不知道具体的原因是什么
