Parameters

pathPathLike

Path to the Zarr array.

Notes

1. The Zarr array is expected to be stored on disk. If the array is not stored on disk, it is recommended to use the PatchedArrayReader class instead.

2. When using padding, the padding is applied to the entire array. This will load the entire array into memory. If the array is too large to fit into memory, it is recommended to pad before.

Examples

```python >>> from pathlib import Path >>> data_path = Path(“data.zarr”) >>> reader = PatchedZarrReader( … path=data_path, … data_shape=(5, 5), … stride=(2, 5), … ) >>> print(len(reader)) >>> print(reader[0])

Parameters:

path (minerva.utils.typing.PathLike)
