UTKFace dataset and imdb/wiki about gender

[cijliu]

hi, I found a bug about gender:
imdb :
gender: 0 for female and 1 for male, NaN if unknown
UTKFace:
[gender] is either 0 (male) or 1 (female)
it will get a adverse gender when use create_db_utkface.py to create UTKFace.mat
the code in 34:
age, gender = image_name.split("_")[:2]
it don't change the gender
