Importlib behaves differently when importing pyd file

[Jach Feng]

My working directory d:\Works\Python\ has a package 'fitz' looks like this:

fitz\
__init__.py
fitz.py
utils.py
_fitz.pyd

There is a statement in fitz.py:
return importlib.import_module('fitz._fitz')

It works fine under Python 3.4 interpreter:
>>> import fitz
>>>

But under Python 3.8 I get an exception:
>>> import fitz
Traceback(...
...
...
ImportError: DLL load failed while importing _fitz
>>>

I work under Windows7 64bit with Python 32bit. Can anyone help?

The Python C-API is Python version dependent.
Your `_fitz.pyd` may need to be recreated for Python 3.8.
