Amazon textextract I can't find trp module

Question

I want to use this amazon table textract script

The problem I encounter is that I don't have any clue what is trp module and how I can install it.

I tried

pip install trp

But when I try to run then I get this error

lib/python3.7/site-packages/trp/__init__.py", line 31
    print ip
           ^
SyntaxError: Missing parentheses in call to 'print'. Did you mean print(ip)?

Answer 1

Apparently it's now in PyPi: https://pypi.org/project/textract-trp/

pip install textract-trp

And then this works...

from trp import Document
doc = Document(blocks)

Answer 2

Create a file name trp.py and paste the below code
