exe generated by pyinstaller doesn't work as expected

Question

I use pyinstaller to convert my py to exe. It contains a UI written by tkinter.

pyinstaller -F my_tool.py

The exe runs normally on my own computer (UI appears in 1-2 min), but when I send it to others, it takes very long time (>15min) to display the UI.

I have no idea of why this happens and how to make the exe respond quickly in other computers. Does anyone know how to deal with it?

---Edit---

I found some warnings in the log and I'm wondering whether the warnings impact the exe:

62194 WARNING: Hidden import "importlib_resources.trees" not found!
62446 WARNING: Conda distribution 'numpy', dependency of 'numpy', was not found. If you installed this distribution with pip then you may ignore this warning.
76721 WARNING: Hidden import "pkg_resources.py2_warn" not found!
76721 WARNING: Hidden import "pkg_resources.markers" not found!

I checked the packages in the env and I have installed numpy, importlib_resources. For pkg_resources, pip throws no matching distribution error.

I also found that the suffix of the output file is '.exe.notanexecutable', not '.exe'.

Answer 1

Uninstall your pyinstaller, then install it from the following link https://github.com/pyinstaller/pyinstaller/tarball/develop most likely, the problem is solved

Answer 2

Yout could use auto-py-to-exe. Thats works for me fine(uses pyinstaller as well). It may add a few parameters that could fix your problem(not shure).

It would be interesting to know what modules your code uses and if it creates a database or so.

Maybe the other pc is just lackin hardware.
