XSeg training stops after loading all samples (no errors)

[arcvaw]

Expected behavior

Attempting to train XSeg by running 5.XSeg) train.bat after generating masks using the default generic XSeg model.

After the XSeg trainer has loaded samples, it should continue on to the filtering stage and then begin training.

Actual behavior

Instead of the trainer continuing after loading samples, it sits idle doing nothing infinitely like this:

There are no errors visibly being logged.

Steps to reproduce

1. Run 5.XSeg) train.bat
2. Select NVIDIA GeForce RTX 2080 SUPER GPU
3. Use whole face type
4. Use a batch size of 8
5. Do not enable pretraining mode
