   I've tried to import a module from a fat jar file and got a ModuleNotFoundError: No module named ... error.

   I checked that the jar file had more than 65k files and was created using Zip64. When I unzip the file, Python is capable of importing the modules.

   I was able to reproduce the error on a simple project, such as:

   simplePackage/
   __init__.py
   a/
   __init__.py
   moduleA.py

   where

   • I'm using Python 3.9.4
   • __init__.py files are empty
   • moduleA.py only has a printA() function

   I ran the following tests:

   1. When importing from the folder, it works

   python
   >>> import sys
   >>> sys.path.append('C:\\Users\\...\\simplePackage')
   >>> from a.moduleA import printA
   >>> printA()
   I'm module a

   2. When zipping the folder, it works

   python
   >>> import sys
   >>> sys.path.append('C:\\Users\\...\\simplePackage.zip')
   >>> from a.moduleA import printA
   >>> printA()
   I'm module a

   3. When forcing to zip with Zip64 it doesn't work

   On linux: zip -fzr simple64Package.zip .

   python
   >>> import sys
   >>> sys.path.append('C:\\Users\\...\\simple64Package.zip')
   >>> from a.moduleA import printA
   Traceback (most recent call last):
     File "<stdin>", line 1, in <module>
   ModuleNotFoundError: No module named 'a'

   Is this an expected behavior? Am I missing something?

   Thanks!
