What happened?

I was trying to divide two DataArray objects, but I needed to check for zero values. I though to do something like: python res = np.divide(a, b, out=np.zeros_like(a, dtype=float), where=b != 0) to get zero whenever b == 0, but running this resulted in a crush of infinite recursion. Part of the traceback is shown below. The full traceback is way too long to post here.

What did you expect to happen?

The division would succeed and I'd get a DataArray with the same dimensions as a and b with the correct results and zero whenever b == 0.

Minimal Complete Verifiable Example

```Python import numpy as np import xarray as xr

a = xr.DataArray([-1, 0, 1, 2, 3], dims="x") b = xr.DataArray([0, 0, 0, 2, 2], dims="x") print(np.divide(a, b, out=np.zeros_like(a, dtype=float), where=b != 0)) ```

MVCE confirmation

  • [X] Minimal example — the example is as focused as reasonably possible to demonstrate the underlying issue in xarray.
  • [X] Complete example — the example is self-contained, including all data and the text of any traceback.
  • [X] Verifiable example — the example copy & pastes into an IPython prompt or Binder notebook, returning the result.
  • [X] New issue — a search of GitHub Issues suggests this is not a duplicate.
  • [X] Recent environment — the issue occurs with the latest version of xarray and its dependencies.
