RTD failure is real:

Well I just fixed the issue to that.

Correct me if I'm wrong, but before pushing my corrected version I pulled the latest version from the remote branch, which seems to contain changes that fail the CI.

cumsum will be a lot more work, see ongoing work in https://github.com/pydata/xarray/pull/7152 . Thanks for looking in to it.

I see, thanks for the heads up :)

I'm running into an issue when trying to directly use the DataArray.reduce method.

At first I used DataArray.cumsum to see the expected behavior: ```

data = np.arange(12).reshape(4,3) da = xr.DataArray(data=data, dims=['x', 'y'], coords={'x': [10, 20, 30, 40], 'y': [70, 80, 90]}) da.cumsum(dim='x') <xarray.DataArray (x: 4, y: 3)> array([[ 0, 1, 2], [ 3, 5, 7], [ 9, 12, 15], [18, 22, 26]]) Coordinates: * x (x) int64 10 20 30 40 * y (y) int64 70 80 90 ```

When I'm trying to achieve the same result through DataArray.reduce I'm running into the following crash: ```

func = xr.DataArray.cumsum da.reduce(func=func, dim='x') Traceback (most recent call last): File "<stdin>", line 1, in <module> File "/mnt/c/Users/GoMaN/Desktop/GoMaN/Projects/xarray/xarray/core/dataarray.py", line 3442, in reduce var = self.variable.reduce(func, dim, axis, keep_attrs, keepdims, kwargs) File "/mnt/c/Users/GoMaN/Desktop/GoMaN/Projects/xarray/xarray/core/variable.py", line 1883, in reduce data = func(self.data, axis=axis, kwargs) File "/mnt/c/Users/GoMaN/Desktop/GoMaN/Projects/xarray/xarray/core/common.py", line 63, in wrapped_func return self.reduce( AttributeError: 'numpy.ndarray' object has no attribute 'reduce' ```

Am I using DataArray.reduce incorrectly?

Thanks in advance :)

I'm trying to figure out how to add examples to DataArray.cumsum and DataArray.cumprod, but it's not so clear to me.

It seems like they have partially dynamic docstrings. I have found the following script in xarray/core/common.py: _cum_extra_args_docstring = dedent( """\ dim : str or sequence of str, optional Dimension over which to apply `{name}`. axis : int or sequence of int, optional Axis over which to apply `{name}`. Only one of the 'dim' and 'axis' arguments can be supplied.""" ) However, it is not clear to me where the rest of the docstring is located, nor where the docstrings of each function (cumsum, cumprod) are located.

I'd appreciate if anybody could direct me to the explanation of this design :)

I noticed that DataArray.interp_like takes an argument called kwargs, but not in the traditional manner which allows passing keyworded arguments (**kwargs).

If this is the intended behavior then I think kwargs is kind of a misleading name for this argument.

I assume you are on windows? Same always happens to me.

Indeed I am.

Thank you very much, I just tried running the script in the same manner on WSL and that seems to give the expected output. Any ideas about how to avoid this issue on Windows?

Thanks for the advice @max-sixty!

I performed doctests on my machine inside a conda venv following the Contributing Guide using Python 3.9, and passed the them.

Yet, it doesn't pass the github tests. Any ideas as to why that might be?
