# Download Conceptual Captions Data
Place data from: https://ai.google.com/research/ConceptualCaptions/download in this folder
`Train_GCC-training.tsv / cc3m.tsv` Training Split (3,318,333)
run `download_data_cc3m.py` or `download_data_cc12m.py`.
Images will be in default LAVIS cache folders. You can stop and resume, the settings for splitting downloads into chunks / threads are not optimal, but it maxed out my connection so i kept them as is.
Note: A previous version of this script used a different file naming scheme, this changed and if you are resuming a previously started download, you will get duplicates.
A bunch of them will fail to download, and return web pages instead. These will need to be cleaned up later. See `downloaded_validation_report.tsv` after it downloads for HTTP errors. Around 8% of images are gone, based on validation set results. Setting the user agent could fix some errors too maybe - not sure if any requests are rejected by sites based on this.
It should take about a day or two to download the training data, keep an eye on disk space.
