Script to download subset OpenImage-O from website using official instructions

[black0017]

Hello, thanks your for your work and especially for the new OOD dataset/benchmark contribution. I am very keen to try it out!!!

Maybe I have missed something in the instructions but:
I see that the information for creating OpenImage-O is not succinct, to the best of my understanding. For this reason, I have created a minimal script to make it easy for others below:

wget https://raw.githubusercontent.com/openimages/dataset/master/downloader.py
# Activate your virtual env and install packages like: `pip install boto3`
python downloader.py ./subset_test_set_open_image_ood.txt   --download_folder=./fold_to_save_the_subset_for_ood_detection/  --num_processes=2

I have followed the instruction from the official OpenImage website

Rename file list in the appropriate format (i have added test/ in the provided filenames):

• subset_test_set_open_image_ood.txt

@waynezhanghk @innerlee @haoqiwang could you please add some instructions like this for future users of your dataset/benchmark?

Thanks again for your dataset contribution and have a nice day!!!!
