torchfits
FITS I/O for PyTorch: read and write FITS as tensors and tables — cutouts, predicate filters, and a shell CLI (C++ engine, vendored CFITSIO).
Prebuilt binary wheels for Python 3.10–3.14 on PyTorch 2.13.x (the wheel ABI lane) — Linux (x86_64, aarch64) and macOS (Apple Silicon arm64), with vendored CFITSIO.
Docs: stable · edge (main tip)
Install
pip install torchfits
Prebuilt wheels decode FITS on the host, then device="cuda" / "mps" copies the tensor onto the GPU when those runtimes are available. For CPU-only installs, custom CUDA builds, or other PyTorch versions, see the Installation guide.

| Task | API |
|---|---|
| Image → tensor | torchfits.read_tensor("img.fits", device="cuda") |
| Write a tensor | torchfits.write("out.fits", tensor) |
| Filter a catalog | torchfits.table.read(..., where="MAG < 20") |
| Columns as tensors | torchfits.table.read_torch(..., where=...) |
| Open a MEF | with torchfits.open("mef.fits") as hdul: … |

Quick start
import torchfits
tensor = torchfits.read_tensor("image.fits", hdu=0, device="cpu")
table = torchfits.table.read(
"catalog.fits",
columns=["RA", "DEC", "MAG_G"],
where="MAG_G < 20.0",
)
torchfits info science.fits
torchfits convert catalog.fits out.parquet --hdu 1
torchfits cutout 'science.fits[100:256,100:256]' cutout.fits
