python - Reduce pyinstaller executable size

I have only one line of code input() written in python and packed with pyinstaller with option --onefile. The exe file is 4577 kB which is almost 5Mb. How can I reduce its size or exclude some auto-bundled libraries?

See Question&Answers more detail:os

Ah, You are not creating the build in a separate virtual environment.

Create a virtual environment just for build purpose and install the packages you need in this environment.

in your cmd execute these to create a virtual enviornment

python -m venv build_env

cd build_env

C:uild_envScriptsActivate

you will see this >>(build_env) C:uild_env

Install all the packages you need for your script, start with pyinstaller

pip install pyinstaller

Once you are all installed, build the exe as before. The exe built using the virtual environment will be faster and smaller in size!! For more details check https://python-forum.io/Thread-pyinstaller-exe-size
