Tensogram Zarr v3 Store Backend
Zarr v3 store backend for Tensogram .tgm files — read and write Tensogram
as if it were a Zarr v3 hierarchy. Works with zarr, xarray, and any
consumer that speaks the Zarr v3 store protocol.
Installation
pip install tensogram-zarr
The tensogram native package and zarr>=3.0 are pulled in automatically.
Usage
import zarr
from tensogram_zarr import TensogramStore
store = TensogramStore("forecast.tgm")
root = zarr.open(store, mode="r")
arr = root["temperature"]
print(arr.shape, arr.dtype)
print(arr[0, :10, :10]) # Zarr-style chunk-aware access
TensogramStore is a standard zarr.abc.store.Store, so the full Zarr
surface (groups, arrays, async reads, region I/O) applies.
