annotation urls for CC, SBU about lavis

[happywu]

also the image loading process seems not adapting to the path defined in lavis/configs/default.yaml, the provided annotation json file for visual genome uses image location of '/export/xxxx', which will cause error when loading images

Hi @happywu , thanks for raising the issue.

We have now updated the SBU annotation URL, see commit for information.

For conceptual captions, there are usually a missing portion of data during downloading. Therefore, our annotations will not be universally applicable to users' local copies. You may instead use the following scripts to generate your annotations and modify the configuration files with the annotation path accordingly.

• lavis/datasets/download_scripts/DownloadConceptualCaptions/create_annotation_3m.ipynb
• lavis/datasets/download_scripts/DownloadConceptualCaptions/create_annotation_12m.ipynb

Let us know how it works.

Thanks.

Thanks for updating the url and guidance for generating CC annotations!
