Using genfromtxt to import csv data with missing values in numpy

I have a csv file that looks something like this (actual file has many more columns and rows):

1,2,3,4,5
6,7,8,9,10
11,12,13,14,15
16

Say the name of the file is info.csv If I try to import this using

data = numpy.genfromtxt('info.csv', delimiter = ',')

then I get the following error:

ValueError: Some errors were detected ! Line #4 (got 1 columns instead of 5)

If I use,

data = numpy.genfromtxt('info.csv', delimiter = ',', skip_fo开发者_高级运维oter = 1) 

both lines with data 16 and with data 11, 12, 13, 14, 15 are skipped. I don't understand why the line with 11, 12, 13, 14, 15 is being skipped. I would appreciate any help on how I can appropriately use the genfromtxt to import first three lines in the above file.

Thanks

if you can ignore the 16 at the end of the file try using the

invalid_raise (bool, optional) parameter if set to False it ignores all incomplete lines without throwing an exception

see here (its the last parameter before the examples) http://docs.scipy.org/doc/numpy/reference/generated/numpy.genfromtxt.html

The command filling_values also helped me. I set it to zero. Thus each empty value is set to zero. It probably doesn't always make sense, but maybe it will help you.
