I came across this cpython issue #1720 (snippets below) which looks similar to the problem we saw. What version of cpython are we using? It seems to be fixed in cython 3.x which uses python3 by default:

Ok, @ncoghlan and I managed to diagnose the issue: Cython emulates Python 2-style implicit relative imports on Python 3 (see ). To disable the Python 3.6 warning, one has to add from __future__ import absolute_import at the top of every Cython source file.

Well, it's a bit surprising to have to add a __future__ import for a functionality that's actually standard in the Python version you're using ;-)

Cython code uses Python 2 syntax and semantics by default, but you can switch to Python 3 syntax/semantics with a compiler option.

I thinking changing the import might clarify the namespace lookup.

from:

import io

to:

from io import BytesIO

BytesIOReader is still used quite heavily in the Cython code. I don’t think it’s used directly in any of the Python code with the possible exception of a test case or two.

would you know if bytesio.pyd and bytesio.pyx are still used? I don’t see any references in the python (.py) code.
