Hello!
The docker container for Python3 is not working because Ubuntu 18 has python 3.6 and when you do pip3 install it will be installed in python 3.6 environment. But pl/container uses python 3.7.
As result I've got and error:
gpadmin=# select test();
ERROR: PL/Container client exception occurred:
Exception occurred in Python during function execution
Traceback (most recent call last):
File "<string>", line 4, in pylog
ModuleNotFoundError: No module named 'nltk'
CONTEXT: PLContainer function "test"
And for check:
$ docker run --rm -it python3:devel bash

The fix for python container is:
RUN python3.7 -m pip install nltk
RUN python3.7 -m nltk.downloader all
