the decompiled file header is like this:

# uncompyle6 version 3.9.0
# Python bytecode version base 3.7.0 (3394)
# Decompiled from: Python 3.7.15 (default, Nov 24 2022, 21:12:53)

and during the decompiling process, i got the following error info:

i don't know where it go wrong...

and i'm not sure what more info is needed, i'm very glad to add more info.

Thx ahead!

Attach the pyc file and src/hc_sim/PVD/device/LoadLock.py if you have that. And please look at https://github.com/rocky/python-uncompyle6/blob/master/.github/ISSUE_TEMPLATE/bug-report.md and https://github.com/rocky/python-uncompyle6/blob/master/HOW-TO-REPORT-A-BUG.md

sorry, the src file is not allowed for upload or any..... is there any other info that i can share with you? certain snippet?

Sorry - when you report an issue here, there is no privacy; and there should be no reason for privacy. In theory you should be stripping down the source code and bytecode to the smallest example that exhibits the problem. In that process anything confidential or personal can be removed or anonymized.

As stated elsewhere, we have a means of generating an unbounded number of decompilation problems where there is both the source code and bytecode, and often these are fairly isolated too.
