Problem about loading model for testing.

Hi, I have a problem when I load the model to have a test.

>> Loading dataset with Mean: 58.50, STD: 13.73

I do not know why I will have this problem since I use the origin code of you. It will help me a lot if you have some experience to address this problem. Thanks!
