Hargreaves PET throws shape error

[jalder-usgs]

Trying to calculated daily PET with Hargreaves throws a “ValueError: The truth value of an array with more than one element is ambiguous. Use a.any() or a.all()” error.

I expect it is from the shape test:
if daily_tmin_celsius.size != daily_tmax_celsius != daily_tmean_celsius:

This should likely be:
if daily_tmin_celsius.size != daily_tmax_celsius.size != daily_tmean_celsius.size:
