Details:

octave's importdata function could not read a large file containing labels for
pixels of an image. The text file contains 
2,17,952 labels. Matlab can read the file in a few seconds and variable
containing the data appears in the workspace.

Octave kept me waiting for half an hour and never read the file.
I'm using octave cli (4.0.0) on windows 7. I have observed the same behaviour
in ubuntu 16.04.


a = importdata('imageLabels.txt');


I have attached the file I was trying to read.
