Creating cx_Freeze exe with Numpy for Python

Question

Im trying to create a basic exe using cx_Freeze. It works for .py programs that don\'t have numpy but I can\'t get one made correctly with numpy.

*Any ideas on ho

Answer 1

This is a bug in cx_Freeze - it doesn't automatically detect that it should copy the module numpy.lib.format. It's already fixed in the development version, so if you're in a position to try that, it should work.

Otherwise, you'll need to specify that numpy.lib.format needs to be included in your setup.py. The line will look something like this:

options = {"build_exe": {"packages": ["numpy.lib.format"]}},

See also the documentation.

Answer 2

I recently encountered this issue using cx_freeze 6.1 and Python 3.5.4. In order to solve my runtime issues, I had to add the numpy lib path to the system paths at runtime. Here is the relevant code snippet if it can help anyone:

if __name__ == '__main__':
# The frozen app needs the numpy path added to it's file.
try:
    this_file = __file__
except NameError:
    this_file = sys.argv[0]
    sys.path.insert(0, str(Path(this_file).absolute().parent / "lib" / "numpy"))

Numpy seems to be a little confusing to cx_Freeze so you need to declare it explicitly. As referenced in the docs

Here is your solution:

   from cx_Freeze import setup, Executable

   build_exe_options = {"packages": ["numpy"]}

   setup(
        name = "Assignment4_5PythonExe",
        version = "0.1",
        description = "Sort Methods",
        options = {"build_exe": build_exe_options},
        executables = [Executable("Assignment4_5.py")]
        )
