I am learning xarray based on pydata's Doc. In Computation section and "Weighted array reductions" sub-section, when I run: weighted_prec = prec.weighted(weights) weighted_prec

Jupyter came back to me below ERROR:

AttributeError Traceback (most recent call last) <ipython-input-49-3893583b4b62> in <module> 1 import pandas as pd 2 import numpy as np ----> 3 data.weighted(weights).mean()

C:\ProgramData\Anaconda3\lib\site-packages\xarray\core\common.py in getattr(self, name) 231 return source[name] 232 raise AttributeError( --> 233 "{!r} object has no attribute {!r}".format(type(self).name, name) 234 ) 235

AttributeError: 'DataArray' object has no attribute 'weighted'

What is my problem?
