In Course5 Week3 Assignment 1 “Neural\_machine\_translation\_with\_attention\_v4a”, when implementing “modelf”, the parameter “macine\_vocab\_size” isn’t used at all (I passed the assignment). Is this expected?

Thanks for bringing this up. The staff have been notified to remove `machine_vocab_size` from the function parameter list of `modelf`.

Happy learning.
