blocks|key|4375916|text|我花了好几个小时才最终确定我需要更新matplotlib。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|4375917|我的原始版本的3.0.3+(与我的jupyter-datascience+docker镜像一起提供)会给我这个错误，但是更新到3.1.1修复了它。|offset|length|style|CODE|4375918|最后，我的docker脚本：|4375919|RUN+pip+install+matplotlib==3.1.1

It took me many hours to finally figure out that I needed to update matplotlib. 

My original version of <code>3.0.3</code> (which came with my jupyter-datascience docker image) would give me this error, but updating to <code>3.1.1</code> fixed it.

In the end, my docker script:

<pre class="lang-sh prettyprint-override"><code>RUN pip install matplotlib==3.1.1
COPY fonts /usr/share/fonts/truetype/
RUN fc-cache -fv
RUN rm /home/jovyan/.cache/matplotlib -rf
</code></pre>

is what did it for me.

try all the methods above, not work for me.

my way to solve this is a little dirrent cause I'm using conda on ubuntu server running jupyter

<pre><code>locate -b '\mpl-data'
</code></pre>

find a folder 

<pre><code>/usr/share/matplotlib/mpl-data
</code></pre>

then I add the simhei fonts into the font folder in mpl-data .
then remove matplotlib fonts cache

<pre><code>rm -rf ~/.cache/matplotlib
</code></pre>

restart jupyter notebook, and it works.

I am in macOS with jupyter notebook, I solved with the following, first close your jupyter notebook. Then find out the font path by doing the following in Python

<pre class="lang-py prettyprint-override"><code>import matplotlib
print(matplotlib.matplotlib_fname())
</code></pre>

it prints <code>/Users/zyy/anaconda2/lib/python2.7/site-packages/matplotlib/mpl-data/matplotlibrc</code> for me, notice <code>matplotlibrc</code> is a file, not a directory.

Then download font <a href="https://github.com/StellarCN/scp_zh/blob/master/fonts/SimHei.ttf" rel="nofollow noreferrer">SimHei</a>, and copy it to the directory <code>fonts/ttf</code> under the <code>mpl-data/</code> directory above.

Delete directory <code>～/.cache/matplotlib</code> and restart your jupyter notebook, everything should be good.

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:

<pre><code>import matplotlib.pyplot as plt
plt.scatter([1,5], [1,5])
</code></pre>

I get an error message:

<pre><code>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]))
</code></pre>

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:

<pre><code>import matplotlib as mpl
fm = mpl.font_manager
fm.get_cachedir()
</code></pre>

The commands:

<pre><code>mpl.rcParams['font.family'] = ['serif']
mpl.rcParams['font.serif'] = ['Times New Roman']
</code></pre>

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/

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

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

Matplotlib cannot find basic fonts

我在一个miniconda虚拟环境中的Python3上使用matplotlib版本2.0.0。我在一个unix科学计算集群上工作，在那里我没有root权限。我通常通过ipython notebook执行python代码。如果我执行一个基本命令，例如：import matplotlib.pyplot as pltplt.scatter([1,5], [1,5])我收到一条错误消息：path_to_m
