What s the problem with my data?

[mkhodakarami]

I ve installed crfsuite on windows7 64 bit.
I have a farsi text,like this:
دولتی ADJ-SIM-GEN O
عربی N-PR-SING O
استقامت N-COM-SING O
و CON O
ایستادگی N-COM،SING-GEN O
افزون‌تر ADJ-CMPR O
از P O
The encoding is windows_1256. when I run the command:
python chunking.py < train.txt > train.crfsuite.txt
I face an error: too few fields (1) for ['w','pos','y'].
What should I do?
