Error while predicting

[juntuck]

Hi there,

I'm a student at the Robotics Chair of TU Munich, and I'm trying to get the activity anticipation code running, but I keep getting this error about 9 hours after running predict_seg:

I followed the steps in README.md, except for $ wget http://web3.cs.cornell.edu/pr/CAD-120/data/Subject1_rgbd_rawtext.tar.gz as the link seems to be dead.
Instead, I downloaded the RGB-D text data for Person 1 from http://pr.cs.cornell.edu/humanactivities/data.php#cad120

Do you know the cause of the error?
