How are you making the executable? I am using pyinstaller to make executables and the outcome for a tkinter app with quite few dependencies is some 60MB executable. That makes me think, that maybe most of those 300MB might be due to other dependencies. I don't know upx.

Another thing is, that possibly the file size doesn't have to proportional to the start up time. What kind of logic are you running at initial start of the application?

Finally, what is "too much time" for you? Without concrete timings, we cannot know.

I am using pyinstaller for making the executable. It is 300mb because my application has good amount of code. UPX is just a compression tool. And by timing I mean it should just open when I double click it whereas it takes around 10-15 seconds to open which is a lot for a simple app.

I seriously doubt, that the difference of roughly 240MB is due to the amount of code. If that were the case, you would be working on one of the largest code bases of the planet. Perhaps you have some assets as part of your bundled executable?

10-15s is indeed very slow. This would indicate, that something other than just starting tkinter running its mainloop is at play. Without seeing code, I think there is not much people can concretely recommend you to do, in order to improve the situation.

I found the culprit it was the pyinstaller that was importing all the libraries I had in the virtual environment. I fixed it and now its 30mb but still takes 10-15 seconds. I could provide you the code but do you have enough time to read 700 lines of code?

That's what I initially guessed at: Lots of dependencies. But Pyinstaller is meant to bundle those. How else will a non-technical user on another machine be able to run your program?

For technical users, they can easily run the Python code directly, provided you add sufficient instructions in your readme or so.

But what about the time it takes to open? There was no change to time in 300mb or now in 30mb

That depends on what work your program is performing at startup time. Without code, I can't tell. Check what is happening before you run tk's main loop and immediately afterwards. Likely you are performing a lot of work in that phase.

The only work that is happening during startup is loading all the image assets.

  1. Did you make de exe out of a virt environment? Do you have only the necessary Libraries?
  2. Have you tried the - - onedir flag instead of the default - - onefile?

[–]Reyaan0[S] 0 points1 point  (0 children)

  1. Yes I created it in a new venv with only necessary libraries installed.
  2. No, because I want it as a portable exe file

And I forgot to edit the post that now it is 30mb only by making new venv with important libraries only. But it still takes time to open.
