| # Large File Merge Instructions | |
| ## Overview | |
| Some large files have been split into 1GB chunks for easier upload/download. The split files are stored in dedicated `*_files/` directories alongside the original file location. | |
| ## Files that need merging | |
| - `kb_index.faiss` (25.3 GB) | |
| - Split into ~26 parts in `2M_kb_eval/echosight_evqa_2M_kb/kb_index_files/` | |
| ## How to Merge | |
| After downloading this dataset, navigate to the specific `*_files/` directory and run the merge script: | |
| ```bash | |
| cd annotation/2M_kb_eval/echosight_evqa_2M_kb/kb_index_files/ | |
| python merge_chunks.py | |
| ``` | |
| This will automatically: | |
| 1. Detect all `.part*` files in current directory | |
| 2. Merge them back into the complete file (e.g., `kb_index.faiss`) | |
| 3. Place the merged file in the parent directory (`../`) | |
| 4. Optionally delete the `.part` files after successful merge | |
| ## Requirements | |
| - Python 3.6+ | |
| - Sufficient disk space (at least 2x the size of the largest file during merge) | |
| ## Verification | |
| After merging, verify the file exists in the parent directory: | |
| ```bash | |
| ls -lh ../kb_index.faiss | |
| ``` | |
| Expected size: ~25.3 GB | |
