>>>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
