We will save the trained model in our local drive in the models folder in our current working directory. To save the model, run the following code −

directory = "./models/"
name = ''handwrittendigitrecognition.h5''
path = os.path.join(save_dir, name)
model.save(path)
print(''Saved trained model at %s '' % path)

The output after running the code is shown below −

Now, as you have saved a trained model, you may use it later on for processing your unknown data.
