I finally reproduced this problem.
I put the `ds.isel(time=[0], isoBaricInhPa=1).z[:, ::10, :][:, ::-1, :]` to
`ds.isel(time=[0], isoBaricInhPa=1).z[:, ::10, ::10][:, ::-1, :]` can make a minimal example.
```
import numpy as np
import xarray as xr
ds = xr.Dataset(
{
""z"": (
(""time"", ""isoBaricInhPa"", ""latitude"", ""longitude""),
np.ones((1, 5, 721, 1440)),
)
},
coords={""latitude"": np.linspace(-90, 90, 721)},
).to_netcdf(""test.nc"")
ds = xr.open_dataset('test.nc')
a = ds.isel(time=[0], isoBaricInhPa=1).z[:, ::10, ::10][:, ::-1, :]
print(a.sizes)
print(a.shape)
print(a)

Since I don't know how the grib file is generated, I can't reproduce it. But the data I use is the ECWMF official website data converted by engine='cfgrib', this problem may be caused by the 'cfgrib' engine, although it is not very big wrong, but it's a hidden danger.

Ok ,thanks. I try to simplify the problem on an array
`a = data3.sel(time='1979-1',isobaricInhPa=200).z[:, ::10,::10][:, ::-1,:]` ,my question is that the coordinates DO NOT correspond to the data, there is 73 on coordinates latitude but only the there is 72 only on real data latitude.","{""total_count"": 0, ""+1"": 0, ""-1"": 0, ""laugh"": 0, ""hooray"": 0, ""confused"": 0, ""heart"": 0, ""rocket"": 0, ""eyes"": 0}",,1222609313

I have added a zip dile with a .ipynb file , don't know if it is ok?

主题: Re: [pydata/xarray] error when using .sel() and [:, ::10, ::10][:, ::-1, :] (Issue #6560)
@jesieleo — I'm probably being unclear, and I'm sure you're well-intentioned, but this & the previous issues aren't constructive for either of us so far.
In the politest possible way: please make an issue that is complete and ""copy & pastes into an IPython prompt or Binder notebook, returning the result."". You cannot reference data that is only on your computer. This will require work from your end to take the example you have there, and reduce it to the bare minimum.
