How to show ML model chart into streamlit

Hi,

I have trained a model (via Keras framework), exported it with model.save('model.hdf5') and now I want to integrate it with the awesome Streamlit.
Obviously, I do not want to load the model every time the end-user insert a new input, but to load it once and for all.
And i want showwm chart of the model in streamlit web application how i do that ?
