Can I use model which is trained using Keras to Scala? I train the NLP classification model using Keras by Python. 
But to deploy the trained model to a platform I need to use Scala. 

Can I use Scala with Keras model what I trained using Python? 

Thanks
Yep, check this blog: https://towardsdatascience.com/deploying-keras-deep-learning-models-with-java-62d80464f34a

Dump your model as .h5 like you normally would and load it in java using those libs from blog.

Another idea would be to create separate AI microservice in python(django/flask). That's what I usually do.
