Imagenet 2012 tfrecord

imagenet2012 TensorFlow Dataset

  1. ILSVRC 2012, commonly known as 'ImageNet' is an image dataset organized according to the WordNet hierarchy. Each meaningful concept in WordNet, possibly described by multiple words or word phrases, is called a synonym set or synset. There are more than 100,000 synsets in WordNet, majority of them are nouns (80,000+)

Since ImageNet changed its rule of downloading the dataset, I could not directly access the dataset via tfds.load. I followed URL to transform local ImageNet 2012 dataset to tfrecord files. However I find it seems to be incompatible with current tfds API, especially tfds.load. I cannot load those tfrecord files through tfds.load Contribute to shl666/imagenet_to_tfrecord development by creating an account on GitHub May 7, 2012: We are preparing to run the ImageNet Large Scale Visual Recognition Challenge 2012 (ILSVRC2012).

所以,比较可行的方法是,自己下载ImageNet-2012,然后来进行转换(TFRecord). 看看代码吧,找找问题,发现涉及如下三个脚本: datasets/preprocess_imagenet_validation_data.py,处理val的数据; datasets/process_bounding_boxes.py,处理boundingbox数据; datasets/build_imagenet_data.py, 构建数据集. 但是其实Imagenet 2012竞赛中是单独提供了验证集的数据的(这部分数据有50000张图片,也是对应这1000个类别)。 Imagenet数据集转换为TFRECORD. 之后就可以对解压后的数据进行读取和处理,把数据转换为TFRECORD的数据格式


Prepare the ImageNet 2012 dataset. Start by downloading the ImageNet classification dataset (choose Download Original Images), which contains more than 140 GB of images. There are two tarballs to download and save to the same directory: Use the TFRecords as the label files for training the Faster R-CNN model This topic describes how to download, pre-process, and upload the ImageNet dataset to use with Cloud TPU. Machine learning models that use the ImageNet dataset include: ResNet; AmoebaNet; EfficientNet; MNASNet; ImageNet is an image database 根据Tensorflow官方整理的Imagenet的数据集,已经转换成TFRecord格式。 自己整理的话需要500G以上硬盘空间,大约两天的时间。整理完成后已完成训练测试,请放心使用 ImageNet 데이터 세트 다운로드. 다운로드 사이트 에서 페이지의 이미지 섹션으로 이동하고 '학습 이미지 (작업 1 및 2)'를 마우스 오른쪽 버튼으로 클릭합니다. 그러면 학습 세트에서 가장 큰 부분을 다운로드하는 데 필요한 URL이 제공됩니다. URL을 저장합니다. Create an EBS volume (1.0TB) for ImageNet dataset and then attach the volume it to your EC2 instance. ImageNet consists of 138GB for training set and 6.3GB for validation set, but we need an additional space since we need to extract tar files as well as need to transform it to the feature sets like TFRecord and RecordIO
