textract_python_table_parser.py command prompt lacking credentials

Question

I'm trying to put to work AWS's Textract export table suggestion in this link I'm a complete newbie in AWS's solutions and in command prompt so I'm trying to do exactly as they suggest. I'm running that in python so I'm using this piece of code:

import os
k=os.system("python textract_python_table_parser.py my_pdf_file_path.pdf")
print(k)

The code runs, I get an Image loaded my_pdf_file_path.pdf however at some point it bugs on credential matters:

Traceback (most recent call last):

I'm aware I didn't pass any credentials and that's natural to happen but where should I pass it and what would be the right syntax for that using python os? Amazon's example doesn't say anything about that.

Answer 1

It depends where you run your code, for example:

• local computer - can use aws configure CLI to set your credetnails
• EC2 instance - use instance role
• lambda function - use lambda execution role
