@lukleu The launch.sh file was just the commands to start Prodigy itself on the container.

#!/usr/bin/env bash

prodigy dataset $(your dataset) $(string name of dataset)
prodigy textcat.........

For my needs, I needed a Text Categorization with a special recipe (to select multiple choices), but YMMV.

@walterg2 thank you Sir! i was suspecting as much but was really unsure

What is in the requirements.txt file?

@teebu then it was

psycopg2
prodigy-1.6.1-cp35.cp36.cp37-cp35m.cp36m.cp37m-linux_x86_64.whl

Probably ancient versions now
