isaacyaf/imagenet2012_ValData_for_mxnet-im2rec

Pre-processing of verification data required by Maxnet

Make sure you have a docker environment in the (/tmp/Imagenet/), It contains the underlying information

1. ILSVRC2012_img_val.tar The dataset is from image.net
2. mkdir_imagenet_2012_validation.sh

wget https://raw.githubusercontent.com/isaacyaf/imagenet2012_ValData_for_mxnet-im2rec/master/mkdir_imagenet_2012_validation.sh

---

3. mv_imagenet_2012_validation.sh

---

wget https://raw.githubusercontent.com/isaacyaf/imagenet2012_ValData_for_mxnet-im2rec/master/mv_imagenet_2012_validation.sh
