[Pytorch/Efficientnet-quant-b0] why I can not get the accuracy 76% for QAT?

Related to Pytorch/Efficientnet QAT

Describe the bug why I could not get hte EfficientNetb0 QAT result as described in the webpage?

To Reproduce Steps to reproduce the behavior: follow the guidance, download the NGC container, run the QAT training code with offical pretrained EfficientNet-b0 result. After more than 100 epochs, I still could not get the 76.5% accuracy. instead, I can only get aobut 73% accuracy. The only difference from offical guidance is I am using batch size 128.

Expected behavior I hope I can get accuracy about 76% for efficientnet-quant-b0

Environment using same as mentioned in the pytorch/efficientnet page.
