Matplotlib无法找到基本字体 [英] Matplotlib cannot find basic fonts

问题描述

我在miniconda虚拟环境中的Python 3上使用了matplotlib版本2.0.0.我正在一个没有root特权的unix科学计算集群上工作.我通常通过ipython笔记本执行python代码.如果我执行基本命令，例如:

I am using matplotlib version 2.0.0 on Python 3 in a miniconda virtual environment. I am working on a unix scientific computing cluster where I don't have root privileges. I am generally executing python code through an ipython notebook. If I do a basic command such as:

import matplotlib.pyplot as plt
plt.scatter([1,5], [1,5])

我收到一条错误消息:

path_to_miniconda/miniconda3/envs/conda34/lib/python3.4/site-
packages/matplotlib/font_manager.py:1297: UserWarning: findfont: Font family
['sans-serif'] not found. Falling back to DejaVu Sans
(prop.get_family(), self.defaultFamily[fontext]))

我希望能够使用Times New Roman字体，但即使删除了从此处找到的字体缓存文件(fontList.py3k.cache)，也可以使用

I would like to be able to use a Times New Roman font but even after deleting the Font cache file (fontList.py3k.cache) which I find from here:

import matplotlib as mpl
fm = mpl.font_manager
fm.get_cachedir()

命令:

mpl.rcParams['font.family'] = ['serif']
mpl.rcParams['font.serif'] = ['Times New Roman']

没有任何作用，我得到了与上述相同的错误.真正的字体目录:

have no effect, I get the same error as above. The true type fonts directory:

path_to_miniconda/miniconda3/envs/conda34/lib/python3.4/site-packages/matplotlib/mpl-data/fonts/ttf/

path_to_miniconda/miniconda3/envs/conda34/lib/python3.4/site-packages/matplotlib/mpl-data/fonts/ttf/

其中只有40种类型的字体:DejaVuSerif，DejaVuSans，STIX，cmb，cmt，cmy

only has 40 fonts in it of the type: DejaVuSerif,DejaVuSans,STIX,cmb, cmt, cmy

有什么想法，怎么添加其他字体?谢谢！

Any idea what could be going on and how I can add additional fonts? Thanks!
