@siddhartamukherjee ,I have run your code in colab. Below is the following error,

Caught FileNotFoundError in DataLoader worker process 0.
Original Traceback (most recent call last):

FileNotFoundError: [Errno 2] No such file or directory: '/content/gdrive/My Drive/PHD_project/NEULOC/NEUDET/train/annotations\rolled-in_scale_21.xml'

But the image mentioned in the above error is surely present.
Please do reply .Thanks in advance.
