Environment data

• debugpy version: 1.8.13
• OS and version: MacOS 15.1
• Python version (& distribution if applicable, e.g. Anaconda): Python 3.13.2
• Using VS Code or Visual Studio: VSCode

Actual behavior

AssertionError: <code object _call_with_frames_removed at 0x1021c8570, file "<frozen importlib._bootstrap>", line 480> != <code object PyInit__frozenlist at 0x10a077b80, file "frozenlist/_frozenlist.pyx", line 1>

Expected behavior

Able to run minimal script

Steps to reproduce:

Install Datasets package and try to run this script with debugger:

from datasets import Dataset

if __name__ == "__main__":
    print("hi")

Thanks for the issue but I can't reproduce your problem. Do you have anything else installed in the venv?

I'm using 3.13.4 and I just installed datasets.

Hello! I ran into the same issue, FYI it seems to be the same as reported here microsoft/vscode-python-debugger#723
As mentioned by someone else in that issue, a temporary workaround is to unset breakpoints before running debugpy

I would hazard a guess that this is a problem with frozenlist. The other issue seems to indicate upgrading to the latest will fix the problem.

This worked for me. Note that it's not limited to frozenlist, we were encountering this with cartopy as well

(posting here rather than as a new issue because I don't have access to the original environment to provide debugging help)
