Tensogram Python Bindings
Python bindings for the Tensogram N-tensor message format.
Native extension built with PyO3 + maturin. Supports NumPy arrays, async I/O, and GIL-free operation on free-threaded Python (3.13t / 3.14t).
Installation
pip install tensogram
# or, with the xarray and Zarr backends:
pip install tensogram[all]
Usage
import numpy as np
import tensogram
data = np.random.randn(100, 200).astype(np.float32)
msg = tensogram.encode(
{"version": 3},
[(
{"type": "ntensor", "shape": [100, 200], "dtype": "float32",
"compression": "szip"},
data,
)],
)
result = tensogram.decode(msg)
arr = result.objects[0][1] # numpy array
Features
- NumPy integration across every supported dtype (float / complex /
int / uint, plus
bitmaskandbfloat16) - Sync and async file APIs (
TensogramFile/AsyncTensogramFile) - GIL-free parallel encode / decode on free-threaded Python
- Partial-range decode (
decode_range) - Full codec support: szip, zstd, lz4, blosc2, zfp, sz3
- Validation (
tensogram.validate,tensogram.validate_file) - GRIB / NetCDF conversion (when the wheel is built with the matching feature)
