See instructions below.\n\n- **Description**:\n\nImageNet-LT is a subset of original ImageNet ILSVRC 2012 dataset. The training\nset is subsampled such that the number of images per class follows a long-tailed\ndistribution. The class with the maximum number of images contains 1,280\nexamples, whereas the class with the minumum number of images contains only 5\nexamples. The dataset also has a balanced validation set, which is also a subset\nof the ImageNet ILSVRC 2012 training set and contains 20 images per class. The\ntest set of this dataset is the same as the validation set of the original\nImageNet ILSVRC 2012 dataset.\n\nThe original ImageNet ILSVRC 2012 dataset must be downloaded manually, and its\npath should be set with --manual_dir in order to generate this dataset.\n\n- **Additional Documentation** :\n [Explore on Papers With Code\n north_east](https://paperswithcode.com/dataset/imagenet-lt)\n\n- **Homepage** :\n \u003chttps://github.com/zhmiao/OpenLongTailRecognition-OLTR\u003e\n\n- **Source code** :\n [`tfds.datasets.imagenet_lt.Builder`](https://github.com/tensorflow/datasets/tree/master/tensorflow_datasets/datasets/imagenet_lt/imagenet_lt_dataset_builder.py)\n\n- **Versions**:\n\n - **`1.0.0`** (default): Initial release.\n- **Download size** : `5.21 MiB`\n\n- **Dataset size** : `20.92 GiB`\n\n- **Manual download instructions** : This dataset requires you to\n download the source data manually into `download_config.manual_dir`\n (defaults to `~/tensorflow_datasets/downloads/manual/`): \n\n manual_dir should contain two files: ILSVRC2012_img_train.tar and\n ILSVRC2012_img_val.tar.\n You need to register on \u003chttp://www.image-net.org/download-images\u003e in order\n to get the link to download the dataset.\n\n- **Auto-cached**\n ([documentation](https://www.tensorflow.org/datasets/performances#auto-caching)):\n No\n\n- **Splits**:\n\n| Split | Examples |\n|----------------|----------|\n| `'test'` | 50,000 |\n| `'train'` | 115,846 |\n| `'validation'` | 20,000 |\n\n- **Feature structure**:\n\n FeaturesDict({\n 'file_name': Text(shape=(), dtype=string),\n 'image': Image(shape=(None, None, 3), dtype=uint8),\n 'label': ClassLabel(shape=(), dtype=int64, num_classes=1000),\n })\n\n- **Feature documentation**:\n\n| Feature | Class | Shape | Dtype | Description |\n|-----------|--------------|-----------------|--------|-------------|\n| | FeaturesDict | | | |\n| file_name | Text | | string | |\n| image | Image | (None, None, 3) | uint8 | |\n| label | ClassLabel | | int64 | |\n\n- **Supervised keys** (See\n [`as_supervised` doc](https://www.tensorflow.org/datasets/api_docs/python/tfds/load#args)):\n `('image', 'label')`\n\n- **Figure**\n ([tfds.show_examples](https://www.tensorflow.org/datasets/api_docs/python/tfds/visualization/show_examples)):\n\n- **Examples** ([tfds.as_dataframe](https://www.tensorflow.org/datasets/api_docs/python/tfds/as_dataframe)):\n\nDisplay examples... \n\n- **Citation**:\n\n \\\n @inproceedings{openlongtailrecognition,\n title={Large-Scale Long-Tailed Recognition in an Open World},\n author={Liu, Ziwei and Miao, Zhongqi and Zhan, Xiaohang and Wang, Jiayun and Gong, Boqing and Yu, Stella X.},\n booktitle={IEEE Conference on Computer Vision and Pattern Recognition (CVPR)},\n year={2019},\n url={https://github.com/zhmiao/OpenLongTailRecognition-OLTR}\n }"]]
