This seems to be new:

AttributeError: module 'dask.array.lib' has no attribute '_stride_tricks_impl'

[keewis]

as far as I can tell, that is an upstream issue (numpy.lib.stride_tricks.sliding_window_view has become an alias of numpy.lib._stride_tricks_impl.sliding_window_view, and dask has a particular way to figure out where to get the implementation for a specific function). See also dask/dask#10347

[headtr1ck]

Now there seem to be quite some cftime related errors.

[spencerkclark]

Regarding the cftime resample errors, a bisect indicates pandas-dev/pandas#52064 changed some answers in pandas. When I get a chance I'll look into how we should address that in xarray.

[headtr1ck]

And some more numpy 2.0 errors :)

Unfortunately this seems to be some issue with h5py. h5netcdf does indeed use that method, not from a ndarray-class instance, but directly as suggested from dtype-instance. The error seems to be issued from h5py (https://github.com/h5py/h5py/blob/f88fb8c5dc5a143037bd5251a7061f6731306209/h5py/_selector.pyx#L344). I'll check with upstream.

[kmuehlbauer]

Heads-up: the last CI Upstream tests seg fault somewhere in the backends-test.

The error seems to be issued from h5py (https://github.com/h5py/h5py/blob/f88fb8c5dc5a143037bd5251a7061f6731306209/h5py/_selector.pyx#L344). I'll check with upstream.

Should be solved by h5py/h5py#2329.

[kmuehlbauer]

Should be solved by h5py/h5py#2329.

The upstream-dev run does use the h5netcdf development version but not the h5py development version. So we will either need to wait for the next h5py-release or also use the h5py development version.

[keewis]

to fix most of the failing backends and the failing iris tests we'd need builds of netcdf4, h5py and cf_units that are compatible with numpy>=2.0.0.dev0 (possibly more). See also #8483.
