| # archives |
|
|
| Original compressed Kubric-4D dataset files, mirrored from the |
| [Generative Camera Dolly project](https://gcd.cs.columbia.edu/#datasets). |
| Credit for the dataset belongs to its original creators. This repository does |
| not change the original data or its usage terms. |
|
|
| Access to data files requires a Hugging Face account and manual approval from |
| the repository owner. The original collection contains 20 archive files totaling |
| 7,652,279,103,561 bytes. Uploading is in progress. Large originals are stored as |
| binary `.partNNN` pieces (approximately 10–16 GB each) to allow reliable |
| verification. Every original listed in `manifests/` has all of its pieces |
| available and verified. Other originals may still be pending. |
|
|
| After downloading the repository, restore the original compressed files with: |
|
|
| ```bash |
| python3 restore_archives.py |
| ``` |
|
|
| The script verifies every piece and the restored original using SHA-256, and |
| refuses to overwrite existing originals. It does not extract archives. See |
| [RESTORE.md](RESTORE.md) for download commands, disk-space requirements, and |
| restoring a single original. The table below describes the original files |
| after restoration. |
|
|
| | Files | Count | Bytes per file | |
| | --- | ---: | ---: | |
| | `gcd_kubric4d_train.tar.gz.aa` through `.aq` | 17 | 400,000,000,000 | |
| | `gcd_kubric4d_train.tar.gz.ar` | 1 | 341,393,715,036 | |
| | `gcd_kubric4d_val.tar.gz` | 1 | 256,464,456,525 | |
| | `gcd_kubric4d_test.tar.gz` | 1 | 254,420,932,000 | |
|
|
| After restoring their `.partNNN` pieces, the 18 training files are consecutive pieces of one gzip-compressed tar stream. |
| They are not independently extractable. After downloading all files, they can |
| be joined in alphabetical order, for example: |
|
|
| ```bash |
| cat gcd_kubric4d_train.tar.gz.a? | tar -xz -C /path/to/output |
| ``` |
|
|
| The validation and test archives can be extracted individually. Extraction is |
| optional and requires additional disk space; the files in this repository are |
| kept compressed; reconstruction reproduces the original bytes exactly. |
