It looks like there is a small change to the GRIDMET elevation netcdf file that breaks the gridmet_ancillary.py script. The array shape was previously 3d (1, 585, 1386), but now the shape is 2d (585, 1386). I'm not sure when this change was made, but as of 17-Sep-2018, it looks like the file was last modified on 11-Sep-2018 (https://climate.northwestknowledge.net/METDATA/data/). There is a fix for this in the develop branch.
