What is the correct folder structure for the dataset?

[debvrat]

Hi,

As per the README.txt, I've setup my CLEVR dataset to look like this -

IODINE-master/data/CLEVR/
	images/
		train/
			CLEVR_train_xxxxxx.png
			CLEVR_train_xxxxxx.png
			.
			.

		test/
			.
			.
			.
		val/
			.
			.
			.
	questions/
	scenes/
	COPYRIGHT.txt
	LICENSE.txt
	README.txt

Is this the right folder structure? Because I'm getting the following error, which I think is probably because the png files are not accessible.
