Matplotlib не может найти семейство без засечек

Этот код

import numpy as np
import matplotlib.pyplot as plt
from matplotlib import rcParams

rcParams.update({
    'font.family':'sans-serif',
    'font.sans-serif':['Helvetica'],
    })

fig, ax = plt.subplots()
im = ax.matshow(np.random.rand(16,16))

plt.show()

дает мне следующее предупреждение:

/usr/lib64/python2.7/site-packages/matplotlib/font_manager.py:1288: UserWarning: 
findfont: Font family [u'sans-serif'] not found. Falling back to Bitstream Vera Sans
(prop.get_family(), self.defaultFamily[fontext]))

Я проверил, у меня установлена ​​Helvetica:

Я также видел этот пост и неоднократно удалял fontList.cache, но безрезультатно.

Как я могу изменить свой шрифт на Helvetica?

Очевидно, это было потому, что мои шрифты были .pcf, а вам нужно .ttf, чтобы писать ими. из-за проблем с лицензированием, по крайней мере, в Gentoo Helvetica недоступна через диспетчер пакетов.

Мое решение состояло в том, чтобы установить media-fonts/liberation-fonts, который является пакетом Gentoo для шрифтов Liberation. Liberation Sans — неплохая замена Helvetica.

Следующий фрагмент кода в основном исправил мой пример:

rcParams.update({
    'font.family':'sans-serif',
    'font.sans-serif':['Liberation Sans'],
    })
