I tried it. It doesn't solve the issue on Kaggle. Still gives the no module named keras.engine error

Hello everyone, I think I have solved this problem. My system is Linux.
I installed :

pip install keras==2.3.1 tensorflow==1.15.0
pip install protobuf==3.20.3
pip install pycocotools
pip install h5py==2.10.0

You could have a try!
