If you want to use multiprocessing as a frozen executable, you need to call multiprocessing.freeze_support() at the beginning of your main script. This will allow multiprocessing to “take over” when it spawns its worker processes. See also https://github.com/pyinstaller/pyinstaller/wiki/Recipe-Multiprocessing
Trick is to make a new directory outside of the one you are building, and then make the build reference the main.py of the Kivy app like in the code below. This fixes permission errors, even from a regular CMD. PS C:\Users\theguy\Documents\Python\myapp-build> python -m PyInstaller –name “MyApp” “C:\Users\theguy\Documents\Python\myapp\main.py”
You can hack the spec file to remove the second instance by adding these lines after a=Analysis: for d in a.datas: if ‘pyconfig’ in d[0]: a.datas.remove(d) break
I accepted the answer above but I post here what I did step by step for complete beginners like me who easily get lost. Before I begin I post my complete test1.py example script with all the modules I actually need. My apologies if it is a bit more complex than the original question but … Read more

Literally just ran into this issue on windows, whereas macOS is okay. I’m building with fbs and PyQt5. The Problem google-api-python-client is not a python module, but a resource, which means you cannot inject it as a hidden-import. googleapiclient.model reads the distribution info from google-api-python-client folder as a packaged resource.

The issue does not come from tkcalendar but from the fact that PyInstaller does not detect second level imports. A way to solve this issue is explained in tkcalendar’s documentation in the HowTos section: When bundling an application with PyInstaller, there is an issue with the detection of the babel dependency of tkcalendar. This can … Read more
You need to use multiprocessing.freeze_support() when you produce a Windows executable with PyInstaller. Straight out from the docs: multiprocessing.freeze_support() Add support for when a program which uses multiprocessing has been frozen to produce a Windows executable. (Has been tested with py2exe, PyInstaller and cx_Freeze.) One needs to call this function straight after the if name … Read more
