Hi @Kamarudin_Anhar and @Sameer_Katija!

Could you please send me your notebooks and your my_model.h5 files via a DM?

You can find these files by clicking in the jupyter logo in the upper left corner of the screen, which will take you to the jupyter filesystem and there you can download the files.


@a-zarta I have shared my file with you via DM.

Hi @Sameer_Katija, in your case the issue was the last Lambda layer in your model. There is a note mentioning that no Lambda layers should be used since they are not required and they are incompatible with the hd5 format.

By removing it you get full score :slight_smile:


@a-zarta Thank you for helping me out. Sure I will remove it and will check again. Thanks
