the error:

Show your code please.
For c extension modules to be used within python, several flags must be enabled when the object is built. Please amend you question to give details for your compilation processes. If _crop_and_resize.so was created with a standard setup.py setup, it is very likely that it is only compatible with identical versions of the cpython interpreter
@AMIRABBAS what is the output of ldd _crop_and_resize.so?
@AMIRABBAS: Stack Overflow is not a service for going to your GitHub repository and diagnosing problems for you. You should narrow your problem down to a specific part of the code and reproduce it with a short program that you post entirely in the question, not as a link to elsewhere.
@AMIRABBAS that is your problem. The file is empty. It did not download for some reason. Redownload it directly from github.

Per @AMIRABBAS's comment, the output of stat _crop_and_resize.so on the Ubuntu 20.04.4 LTS, 64 bit terminal is:

File: _crop_and_resize.so
Size: 0 Blocks: 40 IO Block: regular empty file
Device: Inode: Links: 1

For whatever reason, when downloading the repository, it did not clone the file directly. Needless to say, you cannot link to a zero-length file.

For reference, having downloaded the same file directly from GitHub, the output should be:

~/downloads> stat _crop_and_resize.so
File: _crop_and_resize.so

I successfully downloaded the file, "_crop_and_resize.so" from its repository, and run it again and the current error gone and new error I am receiving!
