TypeError when running prediction (problem with Predictor class)

[meganndare]

Hi, I am trying to use the best checkpoint for ZH provided by you to predict some AMRs given chinese sentences. However, when I run the prediction script, I'm getting a type error (see below). Additionally the same exact error occurs when I tried to run project_test.sh. Any idea how to get around this?
