RuntimeError: shape '[4000000, 1]' is invalid for input of size 4000 When running title-storyline to story model of plan and write

[ehsan-soe]

Hi,

I am trying to train a title-storyline to story model of plan and write paper using this command:

python pytorch_src/main.py --batch_size 20 --train-data rocstory_plan_write/ROCStories_all_merge_tokenize.titlesepkeysepstory.train --valid-data rocstory_plan_write/ROCStories_all_merge_tokenize.titlesepkeysepstory.dev --test-data rocstory_plan_write/ROCStories_all_merge_tokenize.titlesepkeysepstory.test --dropouti 0.4 --dropouth 0.25 --seed 141 --epoch 500 --emsize 1000 --nhid 1000 --save model.pt --vocab-file vocab.pkl

and I am getting this error:

I wonder if you have any idea of what is wrong?

Thanks.
