I haven't checked in VSCode / LSP. I'll investigate this later, it's likely an issue external to xarray.

I moved the accessor code into a file, then imported it:
```python
In [1]: import xarray as xr
   ...: import numpy as np
   ...: import custom_accessor

In [2]: ds = xr.Dataset(
   ...:     {""a"": ((""latitude"", ""longitude""), np.linspace(0, 1, 5 * 10).reshape(5, 10))},
   ...:     coords={""latitude"": np.arange(5), ""longitude"": np.arange(10)},
   ...: )

In [3]: # ds.geo.c<TAB>
   ...: ds.geo.center
Out[3]: (2.0, 4.5)
```
It also works with the builtin `str`, `dt` and `plot` `DataArray` accessors (just not if I'm trying to access the `DataArray`s from a `Dataset` as described above).

Edit: does your accessor work, i.e. does `ds.geo.center` return something?","{""total_count"": 0, ""+1"": 0, ""-1"": 0, ""laugh"": 0, ""hooray"": 0, ""confused"": 0, ""heart"": 0, ""rocket"": 0, ""eyes"": 0}",,536900797

However, we're defining an accessor in ipython. It seems if an accessor is used in a module and that module imported to ipython the autocomplete doesn't work.

Am I missing something?

```python
In [5]: ds = xr.Dataset( 
   ...:     {""a"": ((""latitude"", ""longitude""), np.linspace(0, 1, 5 * 10).reshape(5, 10))}, 
   ...:     coords={
   ...:         ""latitude"": np.arange(5),
   ...:         ""longitude"": np.arange(10),
   ...:         ""time"": np.datetime64(""1999-01-01""),
   ...:     },
   ...: )

In [6]: # ds.time.dt.y<TAB>
   ...: ds.time.dt.y

In [7]: time = ds.time
   ...: # time.dt.y<TAB>
   ...: time.dt.year
