  • Importlib behaves differently when importing pyd file

    From Jach Feng@21:1/5 to All on Tue Nov 15 22:52:07 2022
    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.

    It seems that I have to install pymupdf to use fitz. Thank you.
