**Background:** Support for discovering and loading scripted modules from `.pyc` files has already been implemented for all scripted plugins and modules. You can find the related changes in the [Slicer GitHub repository](https://github.com/search?q=repo%3ASlicer%2FSlicer%20.pyc&type=code).

However, it’s crucial to note that, starting with Python 3.2, the default behavior of [py\_compile.compile](https://docs.python.org/3/library/py_compile.html#py_compile.compile), which is utilized in [ctk\_compile\_python\_scripts.cmake.in](https://github.com/commontk/CTK/blob/master/CMake/ctk_compile_python_scripts.cmake.in), is to generate files like ` __pycache__ /scriptname.cpython-XY.pyc`, following the specifications in [PEP-3147](https://peps.python.org/pep-3147/). This explains why we may not have `*.pyc` files compiled after building the `CompileSlicerPythonFiles` target.

**Update** : To address this, a pull request has been submitted to the CTK repository. This pull request, available at [https://github.com/commontk/CTK/pull/1188](https://github.com/commontk/CTK/pull/1188), aims to ensure that Slicer scripts are consistently compiled as legacy `.pyc` files.

After you have a chance to test and review, we will look into integrating the corresponding changes into Slicer.
