download coco dataset

The coco14/coco17 dataset can be downloaded from here.

In mmfewshot, coco14 is used as default setting, while coco17 is optional. Some methods (attention rpn) were proposed with coco17 data split, which is also evaluated in mmfewshot.

The data structure is as follows:

mmfewshot
├── mmfewshot
├── tools
├── configs
├── data
│   ├── coco
│   │   ├── annotations
│   │   ├── train2014
│   │   ├── val2014
│   │   ├── train2017 (optional)
│   │   ├── val2017 (optional)

download few shot annotations

In mmfewshot, we use the train/val/few shot split of coco14 released in TFA repo. The original data spilt can be found in here.

We provide a re-organized data split. Please download coco.tar.gz and unzip them into $MMFEWSHOT/data/few_shot_ann.

The final data structure is as follows:

mmfewshot
├── mmfewshot
├── tools
├── configs
├── data
│   ├── coco
│   │   ├── annotations
│   │   ├── train2014
│   │   ├── val2014
│   │   ├── train2017 (optional)
│   │   ├── val2017 (optional)
│   ├── few_shot_ann
│   │   ├── coco
│   │   │   ├── annotations
│   │   │   │   ├── train.json
│   │   │   │   ├── val.json
│   │   │   ├── attention_rpn_10shot (for coco17)
│   │   │   ├── benchmark_10shot
│   │   │   ├── benchmark_30shot
