With BatchNormalization + Sigmoid , layers the accuracy(top1) was 82% and top5 accuracy was 97.7%

Deleted sigmoid. Added L2 normalization. Model have difficulty to learn. (Earlier , befor change , it was same problem sometimes). But after get Model with Transfer Learning , model learns good , and everything is ok
