psycopg2-3.11 issue

Greetings 

i copied the folders inside psycopg2-3.11 to my lambda

i got this error while trying to run

[ERROR] Runtime.ImportModuleError: Unable to import module 'lambda_load': /var/task/psycopg2/_psycopg.so: file too short
Traceback (most recent call last):

Am i missing something?

Thanks in advance!
