title: Modifying scikit-learn code locally
body: <p>I am a new python programmer and I just changed an original python file in model_selection folder in anaconda3</p>
  
  <p>However, when I run the code it run the original version not the new one
  Is there any code I can run to make these changes take a place</p>
  
  <p>The full traceback:</p>
  
  <p>Command "C:\Users....\AppData\Local\Continuum\Anaconda3\python.exe -c "import setuptools, tokenize;<strong>file</strong>='C:\Users\...\scikit-learn\setup.py';f‌​=getattr(tokenize, 'open', open)(file);code=f.read().replace('\r\n', '\n');f.close();exec(compile(code, file, 'exec'))" develop --no-deps" failed with error code 1 in C:\Users...\scikit-learn\ –</p>
  
  <p>Thanks </p>
