Description

I try to train a model from scratch on Kinetics-400 using same data as Non-local Network.
the config file is configs/Kinetics/SLOWFAST_8x8_R50.yaml
TRAIN.BATCH_SIZE is set to 64
GPU is 4xP40s,
But I got the top1-acc 74.13% on the validation set.
[INFO: logging.py: 67]: json_stats: {"split": "test_final", "top1_acc": "74.13", "top5_acc": "91.08"}
Is there something need to modify to reproduce the 77% reported in the model zoo?
