Describe the bug
When building docker container to the 2.4.2 I get the following error. This has been tested on two different docker containers that utilize the RethinkDB Python Driver. I have had to use the 2.4.1 driver in order to have docker run.

from rethinkdb import RethinkDB

File "/usr/local/lib/python3.6/dist-packages/rethinkdb/init.py", line 29, in
version = version.VERSION
AttributeError: module 'rethinkdb.version' has no attribute 'VERSION'
