Program crashes on Windows Conda Python 3.x about python-uncompyle6 HOT 9 CLOSED

I just tried decompling this locally on Ubuntu from a command-line and using the open() code and I am not seeing a problem in decompation.

The fact that you are getting that vague error message rather than information from the Python runtime with a stack trace leads me to believe something is weird about your environment or how this gets run from that code.

When you run this from a command-line does that error? When you run from a command-line using option "-a" does the output start:

 L.   2         0  LOAD_CONST               -1
                3  LOAD_CONST               ('hul_ai',)
                6  IMPORT_NAME           0  'custom.pub.ccom'
                9  IMPORT_FROM           1  'hul_ai'
               12  STORE_NAME            1  'hul_ai'
               15  POP_TOP          
             16_0  COLLECTION_START      0  'CONST_LIST'

While I appreciate the fact that you looked at other problems for similarities, I do not see that these are related yet.

That issue had to do with the types of the list values getting confused between variable names and strings as list elements. There is no evidence this is going on here.

Also, there is no report that things crashed let alone a stack trace.

Thank you for your response.

When I run from a command-line using option "-a"，I did indeed receive the output you mentioned.
But when I don't use -a, the result is as follows.

(venv) PS C:\test> uncompyle6 .\26193884.pyc   
# uncompyle6 version 3.9.0
# Python bytecode version base 2.7 (62211)
# Decompiled from: Python 3.10.4 (tags/v3.10.4:9d38120, Mar 23 2022, 23:13:41) [MSC v.1929 64 bit (AMD64)]
# Embedded file name: custom\pub\helper\RL\runtime_models\model_1002000_cpp.py
(venv) PS C:\test> 

In order to better describe the problem, I conducted the following tests.

1. new a python 3.10.4 venv
2. pip install uncompyle6
3. run

import uncompyle6


def main():
  uncompyle6.decompile_file("26193884.pyc")


if __name__ == '__main__':
  main()

I have obtained the following results.

C:\test\venv\Scripts\python.exe C:\test\main.py 
# uncompyle6 version 3.9.0
# Python bytecode version base 2.7 (62211)
# Decompiled from: Python 3.10.4 (tags/v3.10.4:9d38120, Mar 23 2022, 23:13:41) [MSC v.1929 64 bit (AMD64)]

I'm sorry, I think this issue can be closed now. After creating a Python 2.7 environment using conda, it is working fine.

But even when creating a new 3.10 or 3.8 environment using conda, it still doesn't work properly.

I'm sorry, but I still think this is an issue because the uncompyle6 version in 2.7 is outdated. I believe there are still problems with this pyc file even in the version 3.9.0 of uncompyle6. @rocky

You need to prove it then.

from python-uncompyle6.

Thank you, I have made the following attempts.

1. Createnew Python environment.
2. pip install uncompyle6
3. run uncompyle6.decompile_file("28856229.pyc", outstream=sys.stdout)

The conclusion is that this pyc file can only be decompiled correctly in a Python 2 environment,

And when I decompile another pyc file using Python 2, its docstring is displayed as something like "\xe8\x8e\xb7\xe5\x8f\x96\xe4\xb8\x8b\xe4".

I used uncompyle6 3.9.0 throughout the process.

in python 3.10 3.9 3.8 3.6, Output like this:

# uncompyle6 version 3.9.0
# Python bytecode version base 2.7 (62211)
# Decompiled from: Python 3.10.4 (tags/v3.10.4:9d38120, Mar 23 2022, 23:13:41) [MSC v.1929 64 bit (AMD64)]
# Embedded file name: custom\pub\helper\RL\runtime_models\model_1002000_cpp.py

Process finished with exit code -1073741571 (0xC00000FD)

In Python 2.7, it can decompile the source code normally,But the docstring displays incorrectly.

After further testing

it was found that the program works fine on Ubuntu regardless of whether Python 2 or Python 3 is used.

However, it does not work on Windows.

I assure you that this is not due to my personal environment configuration issue.

I'm not sure if this question belongs to Python or this project. I hope to get your answer.
