Instead of going through libsvm in order to access it with Python (I installed libsvm through MacPorts, and import svmutil fails), you might want to install the popular scikit-learn package, which contains an optimized version of libsvm with Python bindings.

The install is very simple with MacPorts: sudo port install py27-scikit-learn (adapt py27 to whatever version of Python you use).

SOLVED:
1. Navigate to http://www.lfd.uci.edu/~gohlke/pythonlibs/#libsvm
2. Download the .whl file of libsvm corresponding to your OS.
3. Open command prompt and navigate to that folder containing the downloaded .whl file.
4. Type the following command in command prompt-

pip install libsvm-3.20-cp27-none-win32.whl

NOTE: Type name of your .whl file after pip install

Easy way to install:

Download libsvm's install binaries from http://www.lfd.uci.edu/~gohlke/pythonlibs/#libsvm You might want to install libsvm‑3.17.win‑amd64‑py2.7.exe or libsvm‑3.17.win32‑py2.7.exe depending upon you windows config

You can do the following:

sudo apt-get install python-libsvm

Download and extract the zip or tar.gz. Run 'make' in the python directory to generate the shared library. You may need to add the location of the shared library to your path. The python modules are in the python directory. More information is found in the readme, also in the python directory.

Alternatively, follow the directions in the readme that's in the python_old directory.

There's also the main readme in the root of the archive.

You shouldn't have to copy any files to your system32 folder unless you are using WindowsXP. The README for libsvm doesn't seem to have been updated for the latest versions of Windows.

Also, you shouldn't have to move the .py files from where you installed libsvm.

If you want to try to get it to work this way, you should restore the original positions of the files and add the path to libsvm to your python paths. Do this by doing something like:

import sys; sys.path.append('/libsvm-3.18/python');

You may still run into problems even after this. There are more painless ways, however. See this question: How do I install libsvm for python under windows 7?

The libsvm package from conda-forge channel provides only the shared library, and not the python bindings. If you want both, I'd suggest you do the following:

conda remove libsvm
conda install pip

Visit http://www.lfd.uci.edu/~gohlke/pythonlibs and download the latest version of libsvm for your version of python and system architecture:

pip install /path/to/downloaded/libsvm-3.21-cp27-cp27m-win_amd64.whl

This wheel package contains the following files:

libsvm-3.21.data/data/Lib/site-packages/libsvm.dll
libsvm-3.21.data/data/Lib/site-packages/svm.py
libsvm-3.21.data/data/Lib/site-packages/svmutil.py
libsvm-3.21.dist-info/DESCRIPTION.rst
libsvm-3.21.dist-info/metadata.json
libsvm-3.21.dist-info/top_level.txt
libsvm-3.21.dist-info/WHEEL
libsvm-3.21.dist-info/METADATA
libsvm-3.21.dist-info/RECORD

libsvm is a C++ package and has a python wrapper. You first need to install the libsvm package itself.

sudo apt install libsvm3

And then install the python wrapper.

sudo apt install python-libsvm

If you are on ubuntu you may use synaptic package manager. It would make life lot easier.

EDIT : For older version of OS, if you use apt-get, use apt-get instead of apt.
