SVM wrapper doesn't work about limdu

Sorry, who are you again? I've not heard from you and I don't remember recommending SVM wrappers to you.

Hi. Sure, we've never been in touch before. I'm referring to documentation that talks about SVM wrapper to avoid quadratic progression in learning time.

What operating system do you use? What do you get if you go to the command line and write: "*svm_perf_learn"* *?* *--- Erel Segal-Halevi (http://erelsgl.github.io <http://erelsgl.github.io>) אראל סגל הלוי*

Ofc, god I really am loosing my mind...

I'm working on Windows 10 (x64). If I run svm_perf_learn I've got:
Not enough input parameters!
Anyway I've used native libraries for textract in the same path and this one works.
Looking in the source code on-line, the check:
if (!SvmPerf.isInstalled()) {
var msg = "Cannot find the executable 'svm_perf_learn'. Please download it from the SvmPerf website, and put a link to it in your path.";
console.error(msg)
throw new Error(msg);
}
it will never be false, because SvmPerf.isInstalled() always return true.
It seems to me that what I get from npm is not aligned to source code.

@corradodebari, please, open the following folder limdu/classifiers/svm
and run node SvmPerfDemo.js
and print here the output.
Thank you.

This the output:

C:\Users\c\Desktop\package\classifiers\svm>svm_perf_learn

Not enough input parameters!

@corradodebari, I think you can try to update the environment variable in Windows and to include the path to the svm_perf_learn, alternativelly you can try to copy svm_perf_learn to %SystemRoot%\system32
and rerun node SvmPerfDemo.js

Hi. Finally I've found the issue.
In SvmPerf.js the checking of svm_perf_learn.exe is done executing this command:
var result = execSync("svm_perf_learn -c 1 a");
the fault is related to the fact that trainingSet file "a" doesn't exist.
Modifing in this way:
var result = execSync("svm_perf_learn");
it works.

I implemented your change. Thanks for the input.
