ImageNet Data

imagnet_data.sh

#Step1:

mkdir /hdd/ImageNet

cd /hdd/ImageNet

#Step2: Download ImageNet data

#Download training images (about 50GB) 
wget -c http://www.image-net.org/challenges/LSVRC/2012/nonpub/ILSVRC2012_img_train.tar &

#Download validation images: 
wget -c http://www.image-net.org/challenges/LSVRC/2012/nonpub/ILSVRC2012_img_val.tar &

#Step3: decompress ImageNet data

#To extract training data 
mkdir train && mv ILSVRC2012_img_train.tar train/ && cd train

tar -xvf ILSVRC2012_img_train.tar && rm -f ILSVRC2012_img_train.tar

find . -name "*.tar" | while read NAME ; do mkdir -p "${NAME%.tar}"; tar -xvf "${NAME}" -C "${NAME%.tar}"; rm -f "${NAME}"; done

// Make sure to check the completeness of the decompression, you should have 1,281,167 images in train folder

#To extract validation data

cd ../ && mkdir val && mv ILSVRC2012_img_val.tar val/ && cd val && tar -xvf ILSVRC2012_img_val.tar
