Read images from a csv file with Octave

Question

I want to read the training.csv file with Octave for the Kaggle competition . The file contains 16 fields. First 15 are the coordinates of keypoints. The 16th is is the image, which is 9216 numbers (0 to 255) separated by space.

Tried, but with no luck the followings:

 - data = csvread('training.csv'); 

 - data = dlmread('training.csv', ',');

 - [l1,l2,l3,l4,l5,l6,l7,l8,l9,l10,l11,l12,l13,l14,l15, image] =
   textread("training.csv", "%f %f %f %f %f %f %f %f %f %f %f %f %f %f
   %f %s", "delimiter", ",", "endofline", "\n", "headerlines", 1);

Note:

• The file also contains missing data.
• The first 3 lines of the csv file are here: pastebin.com/pwBQgcfa

Thanks,

This post contributed greatly to figure this out. The key is to:

• Remove the header row
• Replace the ",," (double commas) with "0"
• Replace "," (single comma) with " " (space)

• The code to read the file

  fn = 'training_space.txt'; M = dlmread(fn);
