I am trying to replicate this paper. I have understood the paper. However, I’m stuck at the first step of creating a DataBunch for this.
I have downloaded the train and val images and have them in a folder.
I have a dictionary mapping the image ids to the captions and I am trying to use the following code to create a DataBunch:
q = (ImageList.from_folder(coco_imgs)
However, it seems like as a target it is expecting classes and not text.
I have been given this warning:
UserWarning: You are labeling your items with CategoryList.
Your valid set contained the following unknown labels, the corresponding items have been discarded.
I have tried going through the codebase for what other kinds of targets are permissible in fastai but I can’t seem to find any.
I did manage to find this example in fastai_dev. However
ObjectDetectDataset is no longer a part of fastai as it now resides in fasai/old/do_not_use
