Dataset.reduce(func, dim=None, keep_attrs=False, numeric_only=False, allow_lazy=False, **kwargs)

Reduce this dataset by applying func along some dimension(s).

Parameters:

Function which can be called in the form f(x, axis=axis, **kwargs) to return the result of reducing an np.ndarray over an integer valued axis.

dim : str or sequence of str, optional

Dimension(s) over which to apply func. By default func is applied over all dimensions.
