What happened?

After installing xarray version 2022.6.0 (currently the latest one) via pip install xarray: $ python -c "import xarray; print(xarray.__version__)" Traceback (most recent call last): File "<string>", line 1, in <module> File "/packages/xarray/xa/lib/python3.9/site-packages/xarray/__init__.py", line 1, in <module> from . import testing, tutorial File "/packages/xarray/xa/lib/python3.9/site-packages/xarray/testing.py", line 9, in <module> from xarray.core import duck_array_ops, formatting, utils File "/packages/xarray/xa/lib/python3.9/site-packages/xarray/core/duck_array_ops.py", line 26, in <module> from . import dask_array_compat, dask_array_ops, dtypes, npcompat, nputils File "/packages/xarray/xa/lib/python3.9/site-packages/xarray/core/npcompat.py", line 72, in <module> _SupportsDType[np.dtype], File "/x86_64/anaconda/3/2021.11/lib/python3.9/typing.py", line 275, in inner return func(*args, **kwds) File "/x86_64/anaconda/3/2021.11/lib/python3.9/typing.py", line 999, in __class_getitem__ _check_generic(cls, params, len(cls.__parameters__)) File "/x86_64/anaconda/3/2021.11/lib/python3.9/typing.py", line 209, in _check_generic raise TypeError(f"{cls} is not a generic class") TypeError: <class 'numpy.typing._dtype_like._SupportsDType'> is not a generic class

My environment includes numpy 1.20.3 which satisfies the minimal requirements in setup.cfg. On the other hand, updating it to version 1.21.0 or downgrading it to 1.19.0 solves the problem.

What did you expect to happen?

Successful import of xarray

Minimal Complete Verifiable Example

Python python -m venv test source test/bin/activate pip install numpy==1.20.0 pip install xarray==2022.06.0 python -c "import xarray"

MVCE confirmation

  • [X] Minimal example — the example is as focused as reasonably possible to demonstrate the underlying issue in xarray.
  • [X] Complete example — the example is self-contained, including all data and the text of any traceback.
  • [ ] Verifiable example — the example copy & pastes into an IPython prompt or Binder notebook, returning the result.
  • [ ] New issue — a search of GitHub Issues suggests this is not a duplicate.
