NameError: name 'TripletLoss' is not defined

[VCPY]

Hello,

thank you for your great project!
I'm currently trying to execute your code. However, when I try to execute the jupyter notebook, cell 6 throws the following error:

model = TripletLoss()
"NameError: name 'TripletLoss' is not defined".

Is there anything which needs to be additionally installed for this?
Best wishes

Edit: Is it possible, that "from model import TripletLossetLoss" is meant to be "from model import TripletLoss"?
