linux Tkinter导入报以下错解决:
Type "help", "copyright", "credits" or "license" for more information. >>> import Tkinter Traceback (most recent call last): File "<stdin>", line 1, in <module> File "/usr/local/python/lib/python2.7/lib-tk/Tkinter.py", line 39, in <module> import _tkinter # If this fails your Python may not be configured for Tk ImportError: No module named _tkinter >>> KeyboardInterrupt >>>
先看原版本python是否可以导入,如果可以的话,直接跳过安装tk等包,否则先后安装tk-devel,python-tk, tcl, tcl-devel等包,然后重新编译安装python,解决

linux中文乱码解决:
Linux、Mac osx 系统中,出现 matplotlib 或 seaborn 绘图中有中文乱码的情形,可以考虑使用以下方式处理:
- 到 anaconda 的 matplotlib 中查看是否有 simhei.ttf 字体:
-
cd ~/anaconda3/lib/python3.5/site-packages/matplotlib/mpl-data/fonts/ttf ls -al | grep simhei
-
- 如果没有,从 windows 中用 everything 搜索全局文件,找到 simhei.ttf,并将其上传到linux 的 matplotlib 的 fonts/ttf 文件夹
- 修改配置文件~/anaconda3/lib/python3.5/site-packages/matplotlib/mpl-data/matplotlibrc 文件, 将该文件拷贝到.cache/matplotlib 目录下,并找到以下两行,改为如下:
-
font.family : sans-serif font.sans-serif : simhei, Bitstream Vera Sans, Lucida Grande, Verdana, Geneva, Lucid, Arial, Helvetica, Avant Garde, sans-serif
-
- (linux)删除~/.cache/matplotlib/目录下的 fonts cache list,
-
rm -r ~/.cache/matplotlib
-
- 代码设置 matplotlib 和 seaborn 的环境
-
import matplotlib as mpl # mpl.rcParams['font.sans-serif'] = ['simhei'] # mpl.rcParams['font.serif'] = ['simhei'] import seaborn as sns sns.set_style("darkgrid",{"font.sans-serif":['simhei','Droid Sans Fallback']})
