VAW dataset location and structure changed

[ans92]

Hi @nirat1606
Thank you for your great work and paper. The location and structure of genome dataset has been changed. It is now moved to following url: https://homes.cs.washington.edu/~ranjay/visualgenome/api.html. Its structure is also changed. Now there is no train, val and test meta files therefore, I am not able to run your notebook to prepare VAW-CZSL dataset. Can you please change your code to accommodate the new changes in the visual genome dataset? I am looking forward to it. Thank you.
