matplotlib中文字体问题排查

article 2024/11/28 23:03:58

本文记录排查Raspberry Pi 4B+Mambaforge+ Python 3.10 + SimHei 下的字体渲染问题

操作系统信息：Linux raspberrypi 6.1.21-v8+ #1642 SMP PREEMPT Mon Apr 3 17:24:16 BST 2023 aarch64 GNU/Linux

字体的安装

字体的安装过程如下

sudo mkdir -p /usr/share/fonts/truetype/custom
sudo cp SimHei.ttf /usr/share/fonts/truetype/custom
sudo fc-cache -fv

确认安装成功使用了

fc-list | grep SimHei

得到结果 /usr/share/fonts/truetype/custom/SimHei.ttf: SimHei,黑体:style=Regular

到这一步安装成功，但是渲染中中文字符还是方框,执行了下面的操作试图fix

sudo apt-get install fonts-wqy-microhei fonts-wqy-zenhei

到这里为止依然不成功，开始进一步问题排查.

问题排查

怀疑matplotlib本身的font cache没有被更新，尽管system的font cache已经用命令进行刷新，并且已经重启了jupyter python kernel.

先打印出matplotlib能够访问到的font进行确认

import matplotlib.font_manager as font_manager

for font in font_manager.fontManager.ttflist:
    print(font)

到这里可以发现没有能访问到安装的SimHei

某些资料表面需要执行font_manager._rebuild(),但是这个操作是报错的，提示模块没有_rebuild这个Attribute.
因为原理是要清理并重建font cache,尝试用一种work-around方式

import shutil
import matplotlib

shutil.rmtree(matplotlib.get_cachedir())

重启Kernel

注意，我们这里要重启kernel,然后再打印进行确认font

import matplotlib.font_manager as font_manager

for font in font_manager.fontManager.ttflist:
    print(font)
