How to prepare ImageNet22K?

[EricLina]

Hello, thanks for your awesome work!

Can you share the ImagetNet22k dataset preparation process?

We downloaded the compressed file of the 21K dataset from the official website and conducted an MD5 check. However, we have encountered the following issues:

• Lack of clear differentiation between the training and validation sets.
• The dataset contains only 19167 categories.
• Some files appear to be corrupted.

Your assistance and guidance on this matter would be greatly appreciated.
