Impala fnv_hash() result not matching the one in Python fnv library

Question

I'm using Impala 3.2.0, and when I run fnv_hash(), I can't seem to be able to match the value with the fnv hash I get using Python, may I know why?

select fnv_hash('test')
7063314956707709637

!pip install fnv
import fnv
fnv.hash(b'test', algorithm=fnv.fnv_1a, bits=64)
