csv2libsvm.py

In this code, we write a basic script to convert a csv file to libsvm format. This example done for this type of csv file:
classs accelX accelY accelZ gyroX gyroY gyroZ
1 -0.329013 1.111466 9.943973 0.064446 -0.0759 -0.095295
1 -0.329013 1.111466 9.943973 0.064446 -0.0759 -0.095295

which 'class'(label) column of the dataframe is the first column.

Converted format is like:
1 1:-0.329013 2:1.111466 3:9.943973 4:0.064446 5:-0.0759 6:-0.095295
1 1:-0.329013 2:1.111466 3:9.943973 4:0.064446 5:-0.0759 6:-0.095295
which makes enable to use libsvm.

Also, example data('data.csv') uploaded to test script.

Usage is like:
python3 csv2libsvm.py -c path_of_input_csv -o path_of_output_folder

For my enviroment I used like:

python3 csv2libsvm.py -c /home/robogor/Desktop/workshop/muhur/data.csv -o /home/robogor/Desktop/
to save file on desktop.

You can change some input arguments to handle your csv data.
