Erro running VQA experiments

Hi,

I encountered the following issue when I ran the train.sh file under src/experiments/vqa/ :

Traceback (most recent call last):
  File "train.py", line 24, in <module>
    from dataGen import VQA
  File "/home/nesl/Documents/SLASH-CE/src/experiments/vqa/dataGen.py", line 9, in <module>
    from trainer import ClauseNTrainer  # the class for training, testing, etc.
  File "/home/nesl/Documents/SLASH-CE/src/experiments/vqa/trainer.py", line 30, in <module>
    from query_lib import QueryManager
  File "/home/nesl/Documents/SLASH-CE/src/experiments/vqa/query_lib.py", line 13, in <module>
    from transformers import DetailTransformer, SimpleTransformer
ModuleNotFoundError: No module named 'transformers'

I'm not sure where the transformer module is coming from.

Start with src/experiments/vqa/train.sh, then follow the imports through train.py, dataGen.py, trainer.py, and query_lib.py to identify how the missing module is expected to be provided. Check the project's documented environment or dependency setup, and consider the issue addressed when the VQA training command gets past the transformers import without this error.
