How do i produce train.hdf5 file to load weights in model ?
or How do i download train.hdf5 file to load weights in model in train.py?

You can skip this step. I think that line was for loading the model that you trained in previous cells.
Or alternatively use this to save the model first
save_model_hdf5(object, filepath, overwrite = TRUE, include_optimizer = TRUE)
and then execute that cell.
