| ## Layout |
|
|
| - `compressed/jsonl/*.jsonl.gz` - gzipped JSONL splits |
| - `compressed/images/images_shard_XXXX.tar.gz` - image shards |
| - `compressed/manifest.jsonl.gz` - absolute to repo path mapping |
| - `shards_index.json` - shard metadata |
|
|
| ## Extract |
|
|
| ```bash |
| # JSONL |
| mkdir -p jsonl && gzip -dc compressed/jsonl/train_DF40_EFS.jsonl.gz > jsonl/train_DF40_EFS.jsonl |
| |
| # Images |
| for shard in compressed/images/images_shard_*.tar.gz; do |
| tar -xzf "$shard" |
| done |
| ``` |
|
|
| ## JSONL format |
|
|
| ```json |
| { |
| "messages": [ |
| { |
| "role": "user", |
| "content": "<image>Is this image real or fake?" |
| }, |
| { |
| "role": "assistant", |
