When I finetune the model with VQAv2,
It produces a lower score than that proposed in the paper. (43%)

Can you explain where this difference comes from and how to fix it??

How many epochs did you run. Did you properly initialized the model weights?

10 epochs and I initialized with pre-trained TVLT weights from huggingface named TVLT.ckpt

Hi! I'm experiencing the same issue and have found no performance difference between randomly initialized models and pre-trained checkpoints.

So, one suspicion is there might be some problems in the initialization. Is there a way to check if the model is properly initialized?
