    import imp
ModuleNotFoundError: No module named 'imp'
Backend QtAgg is interactive backend. Turning interactive mode on.

Expected behavior

Interactive mode is turned on without printing a traceback.

Steps to reproduce:

1. Install matplotlib 3.8.3, PyQt5 5.15.10 and setuptools 69.1.1
2. Debug this script with a breakpoint on the print call:

   import matplotlib
   print()

Hello, following your instructions, I reinstalled matplotlib 3.8.3, PyQt5 5.15.10 and setuptools 69.1.1. However, I still made the above error. Here is my error message. Could you please provide me with some relevant guidance? I would really appreciate it. OS: Windows 11 Python version: 3.12.2 IDE: Pycharm 2024.1

Error: Failed to enable GUI event loop integration for 'qt' Traceback (most recent call last): import imp ModuleNotFoundError: No module named 'imp' Backend QtAgg is interactive backend. Turning interactive mode on.

To support python 3.12 you should change the code in:_vendored/pydevd/_pydevd_bundle/pydevd_utils.py from spec = spec_from_file_location('__main__', file, loader=loader) m = module_from_spec(spec) sys.modules['__main__'] = m return m to ` spec = importlib.util.spec_from_loader('main', loader=None) m = importlib.util.module_from_spec(spec)

Assign the new module to sys.modules['main']

sys.modules['__main__'] = m
return m`
