prediction failed (octave error)

[jawonGim]

First of all, thanks for the docker build sharing.

I've been try to test cdeep3m with docker.
training(+retraining with pre-trained model) with my own dataset was just fine.
I'm faced octave error when predict boundary map with trained model.
this is what the program said.

I googled it, and it seemed this error caused by octave.
DefDataPackages.m done its job properly(I guessed), but octave spit the error after execution of DefDataPackages.
I wonder that is there anybody experience same error I've got and how can I solve this problem.
thanks.
