this error in the console ModuleNotFoundError: No module named 'validate_docbr'

Question

I am making a small project and installed the library "pip3 install validate_docbr". I can use it normally in the console, but when I run an application that imports it, I get the error "ModuleNotFoundError: No module named 'validate_docbr'".

I just wanted to import this function to my code "from validate_docbr import CPF"

from validate_docbr import CPF >>> ModuleNotFoundError: No module named 'validate_docbr'
