It looks like a "path problem". So open easy.py in text editor and go the line 25 which will look something like "gnuplot_exe = r"c:\tmp\Desktop\gnuplot\bin\pgnuplot.exe".
它看起来像一个“路径问题”。所以在文本编辑器中打开easy.py并转到第25行，它看起来像“gnuplot_exe = r”c:\tmp\Desktop\gnuplot\bin\pgnuplot.exe”。
so you need to put the exact path of gnuplot stored , for example for me it was "gnuplot_exe = r"c:\Documents and Settings\Desktop\gnuplot\binary\pgnuplot.exe".
所以你需要输入 gnuplot 存储的确切路径，例如对我来说它是“gnuplot_exe = r”c:\Documents and Settings\Desktop\gnuplot\binary\pgnuplot.exe”。
I Hope this will help you!!!
我希望这能帮到您！！！

- Please check your path of gnuplot.exe, check every character;
- Please install other version of gnuplot, maybe the version of gnuplot is incompatible whih the current version of libSVM;
- In my computer, LibSVM 3.2.1 gnuplot 5.0.1 python 2.7. It is OK!
- 请检查您的 gnuplot.exe 路径，检查每个字符；
- 请安装其他版本的 gnuplot，可能是 gnuplot 的版本与当前版本的 libSVM 不兼容；
- 在我的电脑中，LibSVM 3.2.1 gnuplot 5.0.1 python 2.7。没关系！
