| 688501399 | MDU6SXNzdWU2ODg1MDEzOTk= | 4386 | Zarr store array dtype incorrect | 6130352 | open | 0 | 2 | 2020-08-29T09:54:19Z | 2021-04-20T01:23:45Z | NONE | Writing a boolean array to a zarr store once works, but not twice. The dtype switches to int8 after the second write: ```python import xarray as xr import numpy as np ds = xr.Dataset(dict( x=xr.DataArray(np.random.rand(100) > .5, dims='d1') )) ds.to_zarr('/tmp/ds1.zarr', mode='w') xr.open_zarr('/tmp/ds1.zarr').x.dtype.str # |b1 xr.open_zarr('/tmp/ds1.zarr').to_zarr('/tmp/ds2.zarr', mode='w') xr.open_zarr('/tmp/ds2.zarr').x.dtype.str # |i1 ``` Environment: Output of <tt>xr.show_versions()</tt>INSTALLED VERSIONS ------------------ commit: None python: 3.7.6 | packaged by conda-forge | (default, Jun 1 2020, 18:57:50) [GCC 7.5.0] python-bits: 64 OS: Linux OS-release: 5.4.0-42-generic machine: x86_64 processor: x86_64 byteorder: little LC_ALL: en_US.UTF-8 LANG: en_US.UTF-8 LOCALE: en_US.UTF-8 libhdf5: 1.10.6 libnetcdf: None xarray: 0.16.0 pandas: 1.0.5 numpy: 1.19.0 scipy: 1.5.1 netCDF4: None pydap: None h5netcdf: None h5py: 2.10.0 Nio: None zarr: 2.4.0 cftime: None nc_time_axis: None PseudoNetCDF: None rasterio: None cfgrib: None iris: None bottleneck: None dask: 2.21.0 distributed: 2.21.0 matplotlib: 3.3.0 cartopy: None seaborn: 0.10.1 numbagg: None pint: None setuptools: 47.3.1.post20200616 pip: 20.1.1 conda: 4.8.2 pytest: 5.4.3 IPython: 7.15.0 sphinx: 3.2.1 |
