Replicating Table 4, Image folder error #3

Open LuoyaoChen opened 4 months ago

LuoyaoChen commented 4 months ago

Hi,

I am trying to replicate the numbers in the Table 4, using ImageNet dataset. However, I am seeing this error, for the val/ data folder.

raise FileNotFoundError(f"Couldn't find any class folder in {directory}.")

I saw online that the val/ folder should be of the structure:

val
----
  |-- label_class_0
         |-- image1.JPEG
         |-- image2.JPEG
.....

However, using the imageget website dataset ILSVRC2012, I am not sure how to unzip into label/image.JPEG format automatically. Could you please provide some guidance on how to set up the ImageNet dataset properly?

Thank you very much!

Hi,

Our dataset was downloaded many years ago, and our validation images are sorted into class-specific folders by default. We are not sure what the file structure looks like right now. Do you have any file like val_annotations.txt that details which image belongs to which class? If yes, then you can use that to reconstruct your val/. We also found https://gist.github.com/antoinebrl/7d00d5cb6c95ef194c737392ef7e476a and https://github.com/DoranLyong/ImageNet2012-download, which have data preparation scripts that might help.
