How to modify possible vocab in inverse_vocab

[lanyuchunmo]

Dear author,

When I was switching from p-mod to m-mod, I encountered a problem, I noticed a tip in the “Note” section that "To switch between m-mod and p-mod model, we need to comment/uncomment the possible vocab in inverse_vocab in nmt/input_config.py accordingly ('s', 't', 'y' at line 65, 67, 71)". But when I check the script "nmt/input_config.py", I found that these options ('s', 't', 'y') are located on lines 80, 82 and 86 of the file, respectively. Does this mean that if I want to switch to m-mod, I need to add a "#" to line 80, 83, and 86 to uncomment these lines ( Instead of line 65, 67 and 71).
