I think you need to add more details to this. So do you have an example 
of the problem that includes code and expected output?

Perhaps genfromtxt is probably more appropriate than loadtxt for what 
you want:

from StringIO import StringIO
import numpy as np
t = StringIO("1,1.3,abcde\n2,2.3,wxyz\n1\n3,3.3,mnop")
data = np.genfromtxt(t, 
[('myint','i8'),('myfloat','f8'),('mystring','S5')], names = 
['myint','myfloat','mystring'], delimiter=",", invalid_raise=False)
print 'Bad data raise\n',data

This gives the output that skips the incomplete 3rd line:

/usr/lib64/python2.7/site-packages/numpy/lib/npyio.py:1507: 
ConversionWarning: Some errors were detected !
     Line #3 (got 1 columns instead of 3)
   warnings.warn(errmsg, ConversionWarning)
Bad data raise
[(1, 1.3, 'abcde') (2, 2.3, 'wxyz') (3, 3.3, 'mnop')]
