When using the current official interp function (xarray v0.15.1), the code: ```python datax = xr.DataArray(data=da.from_array(np.arange(0, 4), chunks=2), coords={"x": np.linspace(0, 1, 4)}, dims="x") datay = xr.DataArray(data=da.from_array(np.arange(0, 4), chunks=2), coords={"y": np.linspace(0, 1, 4)}, dims="y") data = datax * datay

# both of these interp call fails
res = datax.interp(x=np.linspace(0, 1))
print(res.load())

res = data.interp(x=np.linspace(0, 1), y=0.5)
print(res.load())

`` fails withNotImplementedError: Chunking along the dimension to be interpolated (0) is not yet supported.`

but succeed with the monkey patched version

EDIT : added the second interp in order to show more general use
