And to train your model with the parameters used in our experiments, use:

CUDA_VISIBLE_DEVICES=0,1 python train.py --exp_name m2_transformer --batch_size 8 --m 40 --head 8 --warmup 10000 --features_path dataset/feature/coco_all_align.hdf5 --annotation_folder dataset/annotations
I get the error as follow:

Why did this error happen? How to solve it?Thank you!
