training over new dataset

I am training it over new dataset. I am getting this error in save checkpoint

Well, i had the same problem. You can make the para 'logppl' and 'logppln' to a very little value, such as 0.0001 in the line 72,73 driver.py.
That works for me.

Dear @goelankur7 , did you finally train your multimodal RNN model successfully? And could you test you own images on your multimodal RNN model?

hey @lebronze, I had this problem as well, and I use the "0.0001". It still doesn't work. Do you have any other fixes?

@agoel-cs @lebronze @infinity0a
how did you create the json file of your own dataset like dataset_coco.json file?
