There is a known issue with psycopg2 on AWS. You have to manually sudo install it.

What I usually do is I include the psycopg2 install (reqires installing postgressql-devel first) in .ebextensions so to make sure it's available before requirements.txt kicks off.

Include this in your config file:

container_commands:
  01_postgresql:
    command: sudo yum -y install gcc python-setuptools python-devel postgresql-devel
  02_postgresql:
    command: sudo easy_install psycopg2
