title: LIBSVM Accuracy Error: Accuracy comes Zero
body: <p>I want to use LIBSVM for electrical load forecasting but my prepared data stucked. People says that labels must be any real number but my data electrical load. How can i convert data or handle this issue? </p>
  
  <p>My Libsvm format: Labels represent electrical load, 1 represents days(1Monday..5 Friday), 2 represents hours(0...23), 3 represents temperature, 4 represents previous load. I have 1745 row like these.I used firslty svm-train.exe( approximtely 70% of data) after svm-predict.exe. Accuracy comes 0 every time. I tried scaling datas. What is the problem in this format?  Where am I doing wrong? If help me, I will be very appreciated.</p>
