VisualBERT_4b_Predictions_Test+Syn.py

""" 10fold Predictions on test and synthetic data
Use models trained on training data (9fold train - 1fold val) to make prediction on associated test and synthetic data.
This file loads models saved in VisualBERT/models folder and make prediction on the datasets.
Predictions made on test are saved in './VisualBERT/Predictions/predictions_test',
predictions made on synthetic are saved in './VisualBERT/Predictions/predictions_syn'

PREDICTIONS ARE NOT EXECUTABLE ON WINDOWS: Issue https://github.com/facebookresearch/mmf/issues/873
    For Windows execution, edit line 77 in file "mmf/mmf/common/test_reporter.py" by substituting ':' with '_'
    line 77 should become: time_format = "%Y-%m-%dT%H_%M_%S"
