Dataloader issue in Kaggle Global Wheat detection dataset

Part 1 (2019) Advanced (Part 1 v3)
1

I am trying to build models for this archived competition using FastAI: https://www.kaggle.com/c/global-wheat-detection/data

Here is my notebook: https://www.kaggle.com/asharma85/pipeline-setup-kaggle
I am unable to correctly display a batch from a dataloader and not sure where the show_batch call is failing exactly

A few questions:

  1. How can I display a few batches in text using dataloaders will this work - next(iter(fastai_dataloader))
  2. Can someone take a look at the notebook and comment what I am doing wrong?

Thanks
