I had a problem generating pair.txt files for my data set.Can you help me?

It is because your folders naming is like "firstname_lastname" where as for this file to run it requires naming format like "firstname_lastname_count"
Rename images in the folder according to LFW format: Name_Surname_0001.jpg, Name_Surname_0002.jpg, etc.
