I've followed through this post .

我正在尝试重现示例 from here

This is how mine looks

This is how it should look

代码在那个页面和这篇文章的末尾

我正在使用的系统

$ lsb_release -a
No LSB modules are available.
Distributor ID: Ubuntu
Description:    Ubuntu 14.04.5 LTS
Release:    14.04
Codename:   trusty

我正在使用的 Python 版本

3.5.2 |Continuum Analytics, Inc.| (default, Jul  2 2016, 17:53:06) 
[GCC 4.4.7 20120313 (Red Hat 4.4.7-1)]

Matplotlib 版本

import matplotlib
matplotlib.__version__
Out[37]: '1.5.1'

系统安装了Humorsans字体

这说明我已经安装了字体

$ fc-list | grep "Humo"
/usr/share/fonts/Humor-Sans-1.0.ttf: Humor Sans:style=Regular
/home/vco/.fonts/Humor-Sans-1.0.ttf: Humor Sans:style=Regular

我正在使用的 Matplotlib 后端

Here is the back end that I'm using

  plt.get_backend()
  Out[42]: 'TkAgg'

输出错误

我已按照帖子 here 中的说明进行操作;

python 输出错误:

/home/vco/anaconda/envs/math_general/lib/python3.5/site-packages/matplotlib/font_manager.py:1288:
UserWarning: findfont: Font family ['Humor Sans', 'Comic Sans MS'] not
found. Falling back to Bitstream Vera Sans

  (prop.get_family(), self.defaultFamily[fontext]))

我也试过把下载的Humorsans字体移到

/usr/share/matplotlib/mpl-data/fonts/ttf

但是还是报了下面的错误

/home/vco/anaconda/envs/math_general/lib/python3.5/site-packages/matplotlib/font_manager.py:1288: UserWarning: findfont: Font family ['Humor Sans', 'Comic Sans MS'] not found. Falling back to Bitstream Vera Sans

代码

from matplotlib import pyplot as plt
import numpy as np

plt.xkcd()

fig = plt.figure()
ax = fig.add_subplot(1, 1, 1)
ax.spines['right'].set_color('none')
ax.spines['top'].set_color('none')
plt.xticks([])
plt.yticks([])
ax.set_ylim([-30, 10])

data = np.ones(100)
data[70:] -= np.arange(30)

plt.annotate(
    'THE DAY I REALIZED\nI COULD COOK BACON\nWHENEVER I WANTED',
    xy=(70, 1), arrowprops=dict(arrowstyle='->'), xytext=(15, -10))

plt.plot(data)

plt.xlabel('time')
plt.ylabel('my overall health')

fig = plt.figure()
ax = fig.add_subplot(1, 1, 1)
ax.bar([-0.125, 1.0-0.125], [0, 100], 0.25)
ax.spines['right'].set_color('none')
ax.spines['top'].set_color('none')
ax.xaxis.set_ticks_position('bottom')
ax.set_xticks([0, 1])
ax.set_xlim([-0.5, 1.5])
ax.set_ylim([0, 110])
ax.set_xticklabels(['CONFIRMED BY\nEXPERIMENT', 'REFUTED BY\nEXPERIMENT'])
plt.yticks([])

plt.title("CLAIMS OF SUPERNATURAL POWERS")

plt.show()

最佳答案

尝试删除 Matplotlib 缓存并查看它是否有效(即，rm -r ~/.cache/matplotlib)。

就我而言，它解决了问题:

user@host:~$ ./xkcd.py
/home/user/.pyenv/versions/3.7.1/lib/python3.7/site-packages/matplotlib/font_manager.py:1241:
UserWarning: findfont: Font family ['xkcd', 'Humor Sans', 'Comic Sans MS'] not found.
Falling back to DejaVu Sans. (prop.get_family(), self.defaultFamily[fontext]))
user@host:~$ rm -r ~/.cache/matplotlib
user@host:~$ ./xkcd.py
