same thing just added ! in front of everything in case you want to run on jupyter

!mkdir coco
!cd coco

a HA
the same thing just added %%bash on the first line of the cell in case you want to run on Jupyter

%%bash

mkdir coco
cd coco
mkdir images
cd images

wget -c http://images.cocodataset.org/zips/train2017.zip
wget -c http://images.cocodataset.org/zips/val2017.zip
wget -c http://images.cocodataset.org/zips/test2017.zip
wget -c http://images.cocodataset.org/zips/unlabeled2017.zip

unzip train2017.zip
unzip val2017.zip
unzip test2017.zip
unzip unlabeled2017.zip

rm train2017.zip

unzip annotations_trainval2017.zip
unzip stuff_annotations_trainval2017.zip
unzip image_info_test2017.zip
unzip image_info_unlabeled2017.zip

rm annotations_trainval2017.zip
rm stuff_annotations_trainval2017.zip
rm image_info_test2017.zip
rm image_info_unlabeled2017.zip

The exact same script but with the modification proposed by @buttercutter and @ben-xD

First open three separate shells and lay out them for convenient use:

On the first one do the following: (you may need to use sudo if permission denied error appears )

mkdir coco
cd coco
mkdir images
cd images
wget -c http://images.cocodataset.org/zips/train2017.zip

On the second:

cd coco/images/
wget -c http://images.cocodataset.org/zips/val2017.zip
wget -c http://images.cocodataset.org/zips/test2017.zip

Note that you will need to press Enter on shell 2 to download test2017.zip after it finishes val2017.zip

On the third:

cd coco/images/
wget -c http://images.cocodataset.org/zips/unlabeled2017.zip

Wait a little while (or do some five-minute stretching 😄 ) until processes on shells one and two finish.

Back on the first shell, issue the following:

unzip train2017.zip
unzip val2017.zip
unzip test2017.zip
unzip unlabeled2017.zip

rm train2017.zip
rm val2017.zip
rm test2017.zip
rm unlabeled2017.zip 

On the second shell:

cd ../
wget -c http://images.cocodataset.org/annotations/annotations_trainval2017.zip
wget -c http://images.cocodataset.org/annotations/stuff_annotations_trainval2017.zip
wget -c http://images.cocodataset.org/annotations/image_info_test2017.zip
wget -c http://images.cocodataset.org/annotations/image_info_unlabeled2017.zip

unzip annotations_trainval2017.zip
unzip stuff_annotations_trainval2017.zip
unzip image_info_test2017.zip
unzip image_info_unlabeled2017.zip

rm annotations_trainval2017.zip
rm stuff_annotations_trainval2017.zip
rm image_info_test2017.zip
rm image_info_unlabeled2017.zip

By the time shells one and two finish, the shell three will have finished its job. Hope it helps save some time. 🤝

Great! Thanks, the only think that might further improve it would be to rm zip file right after having unzipped them. Might be useful for all the people that while working on VMs might have memory constraints

same script but instead of 5 min stretch, try doing squats.

Everything but Claude Haiku-fied with <script> + separate and run them in parallel (maybe background processes)
