@beniz thanks for the reply . That is true , fine-tune my neural , that's my next step . Again , I want to thank you for your building up this software , which make it much easier to get into deep learning . I read a lot and watch a lot of videos , only you are providing detailed hands on & entry level material and plug & play software for deep learning . One more suggestion , if you can record videos (3-5 mins ) , together with your tutorials , will help a lot people . i guess I will need to talk to you on the possibility of professional consultant very soon if possible .
