I have installed keras and when I'm trying to import resnet by command

# from resnet.py
import resnet

I'm getting the below error

ImportError: cannot import name 'BatchNormalization' from 'keras.layers.normalization' (C:\Users\Toshiba\anaconda3\lib\site-packages\keras\layers\normalization\__init__.py)

After importing resnet I have to build model using resnet18
