Need help understanding copy_attn_force

Hi there,

I am trying to figure out what this option copy_attn_force does? I understand that it is optionally used when you want to use the copy mechanism, in CopyGeneratorCriterion class in for calculating the output probability. However, I didn’ understand the comments for NOT using copy_attn_force: Regular prob (no unks and unks that can't be copied). What does this comment mean? Some explanation is greatly appreciated!!

Could you open an issue on GitHub with your question? There are more PyTorch devs there to answer questions about code details.


OK, will do. Thanks!
