just a small recommendation, try to use wget -c instead of just wget in order to allow resume download for partially downloaded file
The exact same script but with the modification proposed by @promach
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

Although this script is convenient, when using a cloud VM to download these files, you can potentially save a bit of time by running all the downloads in separate shells. I found that running 1 at once gave me 22.4/s for it, 4 at once gave me about 22.4MB/s each.
