Problem found.

Another example with more minimalistic code :

```python zname = '/tmp/test.zarr' zh = zarr.open(zname, "w")

data = np.ones(10, dtype=np.uint32) za = zh.array("example", data) za.attrs["_ARRAY_DIMENSIONS"] = ["obs"] # or won't be read by xarray

print("zarr : ", za.dtype, za[:])

ds = xr.open_zarr(zname) print("xarray : ", ds.example.dtype, ds.example.values) python

zarr : uint32 [1 1 1 1 1 1 1 1 1 1] xarray : float64 [1. 1. 1. 1. 1. 1. 1. 1. 1. 1.] ```

After investigations, i found that you have to explicitly pass fill_value=None :

```python zname = '/tmp/test.zarr' zh = zarr.open(zname, "w")

data = np.ones(10, dtype=np.uint32) za = zh.array("example", data, fill_value=None) # <-- default fill_value=0

za.attrs["_ARRAY_DIMENSIONS"] = ["obs"] print("zarr : ", za.dtype, za[:])

ds = xr.open_zarr(zname) print("xarray : ", ds.example.dtype, ds.example.values) python

zarr : uint32 [1 1 1 1 1 1 1 1 1 1] xarray : uint32 [1 1 1 1 1 1 1 1 1 1] ```

ok I missread the documentation. Adding

xr.set_options(keep_attrs=True)

copy attributes correctly.
