Datasets

We prepare the pre-training corpus following OSCAR and BLIP. As the data prepartion is very time consuming, we provide our experience for reference.

1. Download Datasets (images)

Pre-train Datasets:

CC3M

Step1: First download train/val/test annotation files include URL from google-research-datasets.

Step2: We provided our script for downloading and split CC3M into subsplit in cc3m_download.py. It's better to use our cript for downloading as the filename maybe different with different preprocess.

Notice we only download 2.8M data as some URLs has invalid.

SBU

First from annotation files include URL from huggingface.

Tip: We provided our script for downloading sbu: download_sbu.py

Visual Genome

Download image (version1.2) from visualgenome.

The download dirs will be VG_100K and VG_100K_2.

mkdir image
mv VG_100K/* image/
mv VG_100K_2/* image/

COCO

Down image (coco2014) from coco. Download 2014 Train, 2014 val and 2015 Test images.

CC12M

Step1: Download annotation files include URLs from google-research-datasets.

Step2: Just modify the source tsv file and image path in cc3m_download.py. Then download data the same as cc3m.

Notice we only download 10M data as some URLs has invalid.

Fine-tune Datasets:

COCO

Down image (coco2014) from coco. Download 2014 Train, 2014 val, 2014 test and 2015 Test images.

Flickr30K

Download image from kaggle.

VQA V2

Download images from VQA.

NLVR

Download images from NLVR.

Originze Datasets

Prepare the datasets as follow:

Dataset/
    CC3M/
        images/
            train/x/*.jpg
            val/x/*.jpg
    SBU/
        dataset/
            train/x/*.png
    coco2014/
        COCO2014/
            train2014/*.jpg
            val2014/*.jpg
            test2015/*.jpg
    
    VisualGenome/
        image/*.jpg

Use soft link to map directory, for example

ln -s [PATH_TO_COCO2014] Dataset/coco2014/COCO2014

2. Download/Prepare Corpus (image-text pair)

We provide two kinds of shuffled image-text pair. We use object information from OSCAR and follow BLIP for caption refine.

  1. Specifically, we download corups and object features from OSCAR codebase first. Follow download_cc3m_predictions.sh for details. Download COCOTrain, CC Train, SBU (all) and VG.
  2. Then Generate object_bbox and object_classes from object feature. Follow generate_sample_with_bbox_and_classes.py for details.
  3. At last, use generated caption to padding with origing caption, follow BLIP.

Notice each COCO image include 5 text in oscar corpus. As COCO is high-quality caption, it will affect the final downstream result much.

Make sure each line in corpus is

[image, refined_caption, object_bbox, object_classes]

A example is given below:

CC3M/images/train/1597/3250687125.jpg   i shall be bringing this white chair and table to the shoot; a white table with two white chairs and a couch    [[340, 226, 417, 323], [16, 364, 348, 810], [256, 206, 380, 325], [195, 322, 627, 899], [0, 0, 192, 288], [568, 198, 730, 335], [95, 107, 202, 141], [531, 0, 732, 191], [666, 244, 734, 369], [378, 208, 677, 341]] ['pillow', 'chair', 'pillow', 'table', 'window', 'pillow', 'box', 'window', 'pillow', 'pillow']
  • 2.8M Image (2G): CC3M

Thanks Jaeseok Byun for helping correct this corpus.

As we used all spaces for huggingface and google driver now, follow mentonied way to prepare more large corpus.
