**警告原因**：matplotlib中文乱码问题

##### 解决办法 #####

1、在终端python 的环境下，查看字体路径

import matplotlib    
    print(matplotlib.matplotlib_fname())

![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3NpbmF0XzQwODc1MDc4_size_16_color_FFFFFF_t_70 1]  
2、下载SimHei  
[官方下载网址][Link 1]，并前往指定目录:`/Library/Frameworks/Python.framework/Versions/3.6/lib/python3.6/site-packages/matplotlib/mpl-data/fonts/ttf`，将下载好的SimHei移动到该目录下。  
3、删除matplotlib的缓冲目录  
在终端python 的环境下，输入如下指令，查看matplotlib的字体缓存路径：

import matplotlib
    matplotlib.get_cachedir()

然后使用`rm -rf +路径`删除缓存

4、修改matplotlibrc文件  
修改/Library/Frameworks/Python.framework/Versions/3.6/lib/python3.6/site-packages/matplotlib/mpl-data/matplotlibrc，修改内容如下：

font.family         : sans-serif   
     # 去掉前面的# 
     font.sans-serif     : SimHei, Bitstream Vera Sans, Lucida Grande, Verdana, Geneva, Lucid, Arial, Helvetica, Avant Garde, sans-serif  
     # 去掉前面的#，并在冒号后面添加SimHei
     axes.unicode_minus  : False
     # 去掉前面的#，并将True改为False

5、重新启动Eclipse。
