Hi, I am trying to reproduce the index-variable with the same data, dims, attributes, yet I got the following error message

```python-traceback Traceback (most recent call last):

The file is on Box drive. https://app.box.com/s/vc8m9c9blue3svbm9v7fy0xg1rkthut0 tmp_file = xr.open_dataset('olr.day.mean.nc') latP = tmp_file.variables['lat'] latPP=xr.IndexVariable(latP.data,latP.dims,latP.attrs)
