training custom datasets

[Abdullah Ibrahim]

Hi guys,

i'm new in using caffe, i'm trying to train caffe for custom dataset, group of some images, i have created train.txt, my question is the second field in the file must be an index for the label of image or i can just push the label directly there as example: mydata/01313_e434l3JKtt6_600x450.JPEG 0

or it's okay to do this:

mydata/01313_e434l3JKtt6_600x450.JPEG bird

if it should be index as in first example, what other file should be created, i can not understand this part, can anybody please help me out?

I believe they must be sequential numbers starting with 0, each digit representing a different class. 

Think of them as indexes into an array of classes. You would make another file to map the indexes to the class names, with your own code.
