Imagenet2012 validation set

Imagenet은 torrent로 다운받는다. 공식 사이트는 인증 관련해서 변경사항이 있어서 쉽게 다운로드가 되지 않는다.

imagenet2012.tar는 디텍토리가 없으므로 잘 지정해서 압축을 해제한다. 5만장의 이미지들로 구성되어 있음.

tar xvf ILSVRC2012_img_val.tar -C /root/Desktop/folder

Validation set 정리

bash shell을 이용한 방법
아래의 스크립트로 이미지들을 label에 맞게 디렉토리를 생성해서 분류해줘야한다. 하지만 mlperf에서는 val_map.txt로 동작하기 때문에 기존의 validation set 정제 작업은 필요하지 않다.

wget -qO- https://raw.githubusercontent.com/soumith/imagenetloader.torch/master/valprep.sh | bash

Python 코드를 이용한 방법
원본 주소: https://github.com/tensorflow/models/blob/master/research/inception/inception/data/preprocess_imagenet_validation_data.py

"""Process the ImageNet Challenge bounding boxes for TensorFlow model training.
Associate the ImageNet 2012 Challenge validation data set with labels.
The raw ImageNet validation data set is expected to reside in JPEG files
located in the following directory structure.
 data_dir/ILSVRC2012_val_00000001.JPEG
 data_dir/ILSVRC2012_val_00000002.JPEG
 ...
 data_dir/ILSVRC2012_val_00050000.JPEG
This script moves the files into a directory structure like such:
 data_dir/n01440764/ILSVRC2012_val_00000293.JPEG
 data_dir/n01440764/ILSVRC2012_val_00000543.JPEG
 ...
where 'n01440764' is the unique synset label associated with
these images.
This directory reorganization requires a mapping from validation image
number (i.e. suffix of the original file) to the associated label. This
is provided in the ImageNet development kit via a Matlab file.
In order to make life easier and divorce ourselves from Matlab, we instead
supply a custom text file that provides this mapping for us.
Sample usage:
  ./preprocess_imagenet_validation_data.py ILSVRC2012_img_val \
  imagenet_2012_validation_synset_labels.txt
