Answer 1

You can use csv2libsvm.py to convert csv to libsvm data

python csv2libsvm.py iris.csv libsvm.data 4 True

where 4 means target index, and True means csv has a header.

Finally, you can get libsvm.data as

0 1:5.1 2:3.5 3:1.4 4:0.2
0 1:4.9 2:3.0 3:1.4 4:0.2
0 1:4.7 2:3.2 3:1.3 4:0.2
0 1:4.6 2:3.1 3:1.5 4:0.2
...

from iris.csv

150,4,setosa,versicolor,virginica
5.1,3.5,1.4,0.2,0
4.9,3.0,1.4,0.2,0
4.7,3.2,1.3,0.2,0
4.6,3.1,1.5,0.2,0
