I am trying to prepare an executable using cx_Freeze but get the following error :

and here is my setup.py file :

from cx_Freeze import setup, Executable

base = None

executables = [Executable("Abkuehlzeit_HP_GUI.py", base=base)]

packages = ["idna","pandas","numpy","sklearn","tkinter","sklearn.model_selection"]
options = {
    'build_exe': {
        'packages':packages,
    },
}

setup(
    name = "Prediction_Tool",
    options = options,
    version = "1.0",
    description = '',
    executables = executables
)

Note : I tried making an executable using Pyinstaller and it worked, however the structure of the sub-folders and files in the destination folder is really unorganized, the structure of cx_Freeze is much more organized. Any help would be appreciated :)

Answer 1

I just had the same issue. You're correct that downgrading cx_Freeze to 6.1 fixes it. I also found another workaround: delete (or move someplace else) the directory lib\site-packages\numpy\random\_examples.

It seems to be fixed by this: https://github.com/marcelotduarte/cx_Freeze/pull/695 so we can expect version 6.3 to fix this when it's released eventually.

The problem (or a very similar one) is mentioned in https://github.com/marcelotduarte/cx_Freeze/issues/692 and https://github.com/marcelotduarte/cx_Freeze/issues/705. A comment in #705 also suggests eliminating the use of replace_paths as a workaround (which doesn't apply to your particular case but might to others).

Until 6.3 is released, if downgrading to 6.1 is not an option, you may want to try updating to the current development version using pip install -U git+https://github.com/marcelotduarte/cx_Freeze.git@master (at your own risk).
