Metrics=['accuracy'] or ['acc'] in model.compile()

This is a general question:
I see that either metrics=[‘accuracy’] or metrics=[‘acc’] is used in model.compile()

Which is right/preferred?

I dont think its a matter of preference but Tensorflow/Keras at the model class might be using both terms. Sometimes with time one might become depreciated so you need to check which one they suggest.
