issue with test pdf file

[kiashann]

Hi. I installed the library on Google Colab and I ran the below instruction but I got the following error.

!psr pdf2csv '/content/bank-statement.pdf'

How can I use it in python code?
Error:
Traceback (most recent call last):

The above exception was the direct cause of the following exception:
