numcodecs Compression / Decompression Starter

Use this skill to round-trip a small integer matrix through a deterministic numcodecs compressor and inspect the encoded payload summary.

What This Skill Does

  • reads a tiny tabular integer matrix
  • encodes the matrix bytes with numcodecs.Blosc
  • decodes the payload and verifies lossless recovery
  • reports shape, dtype, encoded byte count, and simple row statistics

When To Use It

  • when you need a starter for compression-decompression
  • when you want a repo-local numcodecs example outside the full Zarr stack
  • when you need a small regression fixture for round-trip codec checks

Run

./slurm/envs/data-tools/bin/python skills/data-acquisition-and-dataset-handling/numcodecs-compression-decompression-starter/scripts/run_numcodecs_compression_decompression.py --input skills/data-acquisition-and-dataset-handling/numcodecs-compression-decompression-starter/examples/toy_matrix.tsv --out scratch/numcodecs/toy_matrix_summary.json

Notes

  • The codec configuration is fixed so the canonical asset stays stable.
  • The example is intentionally tiny and integer-only; validate codec choices on real payloads before production use.
