Hello,
In many examples of using of pdfminer, there are imports like this:

from pdfminer.pdfinterp import PDFResourceManager, PDFPageInterpreter

I installed pdfminer (version 20191125according to pip list).
But there is no pdfinterp inside pdfminer.
Any comments ?
Thanks

When I run the posted code I don't get any error messages. I also looked at the project page and saw there is a pdfinterp submodule.

What is the error message?
Do you get an import error if you "import pdfminer"? I have installed packages in the wrong Python in the past. Easy to do when you have multiple virtual environments.

What is your pdfminer version ?

Output:
>>> from pdfminer.pdfinterp import PDFPageInterpreter

I am using pdfminer 20191125 with Python 3.9.0.

What does this print?

import pkgutil, pdfminer

for a, modname, c in pkgutil.walk_packages(path=pdfminer.__path__):
    print(modname)

I get this:

You are not importing pdfminer. What do you see when you run this?

import pdfminer

print(pdfminer.__file__)

How are you running this code? What Python are you using? Which OS? How do you run Python?

Look if have named a file pdfminer.py or folder,is a common mistake in these cases.
Do this.

>>> import pdfminer
>>> 
>>> dir(pdfminer)
['__builtins__',
 '__cached__',
 '__doc__',
 '__file__',
 '__loader__',
 '__name__',
 '__package__',
 '__path__',
 '__spec__',
 '__version__']

So these are the specials methods in pdfminer.
If you see something else or nothing then you import a file/folder that is not pdfminer.
pdfinterp import the ordinary methods it has.

>> import pdfminer.pdfinterp
>>> 
>>> dir(pdfminer)
['__builtins__',
 '__cached__',
 '__doc__',
 '__file__',
 '__loader__',
 '__name__',
 '__package__',
 '__path__',
 '__spec__',
 '__version__',

A pdfminer.py somewhere in the path was what I was thinking, but what kind of file doesn't raise an import error and doesn't have a __file__ attribute? I cannot make that happen if I try.
