To create the minimum size executable with PyInstaller, you can use the --onefile flag when running the PyInstaller command. This flag packages the executable into a single file, which can help reduce the overall size of the executable. Additionally, you can use the --noconsole flag to create a GUI-only executable, which can also help reduce the file size. Make sure to include only the necessary dependencies and files in the package to further minimize the size of the executable. Lastly, consider optimizing your code and removing any unnecessary libraries or modules to create a smaller executable size.

How to bundle multiple Python scripts into a single executable with pyinstaller?
To bundle multiple Python scripts into a single executable using PyInstaller, follow these steps:
- Install PyInstaller: First, you need to install PyInstaller on your system if you haven't already. You can do this using pip:
1
|
pip install pyinstaller
|
- Create a spec file: Create a spec file that specifies which Python scripts you want to bundle into a single executable. You can create a spec file using the following command:
1
|
pyi-makespec your_script.py
|
This will create a your_script.spec file.
- Edit the spec file: Open the spec file in a text editor and add the paths to the other Python scripts that you want to include in the coll variable under the Analysis section. For example:
1
|
coll = COLLECT(exe, a.binaries, a.zipfiles, a.datas + [('path_to_script2.py', '.')])
|
- Build the executable: Once you have edited the spec file, you can build the executable using the following command:
1
|
pyinstaller your_script.spec
|
This will bundle all the specified Python scripts into a single executable.
- Run the executable: Once the build process is complete, you can find the executable in the dist directory. You can run the executable like any other compiled program.
That's it! You have successfully bundled multiple Python scripts into a single executable using PyInstaller.
How to create a standalone executable with pyinstaller?
To create a standalone executable with PyInstaller, follow these steps:
- Install PyInstaller: First, you need to install PyInstaller if you haven't already. You can do this using pip by running the following command:
1
|
pip install pyinstaller
|
- Create your Python script: Write your Python script that you want to convert into an executable. Save it as my_script.py.
- Open a terminal: Open a terminal window in the directory where your Python script is located.
- Run PyInstaller: In the terminal, run the following command to create a standalone executable:
1
|
pyinstaller --onefile my_script.py
|
This command will package your script and its dependencies into a single executable file located in the dist directory within your project folder.
- Test the executable: Navigate to the dist directory and run the generated executable file to test if it works as expected.
That's it! You have successfully created a standalone executable with PyInstaller. You can distribute this executable to others without the need for them to have Python or any dependencies installed.
How to troubleshoot common issues with pyinstaller?
Here are some common issues with PyInstaller and how to troubleshoot them:
- Missing files or modules: If PyInstaller is unable to find certain files or modules during the packaging process, you can try specifying the paths to these files or modules using the --paths or --hidden-import flags. Make sure to also check for any misspelled or incorrect paths.
- Executable not running on different machine: If the executable created by PyInstaller is not running on a different machine, check if the machine has the necessary runtime libraries or dependencies installed. You can use the --onedir option to create a directory with all the necessary files for running the executable on another machine.
- Large size of the executable: If the size of the executable is too large, you can try using the --onefile option to create a single executable file instead of multiple files. This can help reduce the overall size of the executable.
- Frozen application crashes or does not start: If the frozen application crashes or does not start, you can try running the application in debug mode using the --debug flag. This will provide more information about any errors or issues that may be causing the problem.
- Missing DLL files: If the frozen application is missing certain DLL files, you can try manually copying these files to the same directory as the executable or specifying the paths to these files using the --path or --add-binary flags.
By following these troubleshooting tips, you should be able to resolve common issues with PyInstaller and successfully package your Python scripts into standalone executables.
How to optimize the size of an executable created with pyinstaller?
There are several ways to optimize the size of an executable created with PyInstaller:
- Remove unnecessary files: You can use the --exclude-module option to exclude unnecessary modules and reduce the size of the executable. You can also manually delete unnecessary files from the dist folder.
- Compile with one file option: Using the --onefile option will package your application into a single executable file, which can help reduce the overall size.
- Use UPX compression: PyInstaller has the option to use UPX compression to compress the executable file, which can significantly reduce its size. You can use the --upx-dir option to enable UPX compression.
- Optimize imports: PyInstaller sometimes includes unnecessary packages in the executable. You can optimize imports by manually specifying the required packages in the spec file or using the --no-internal-imports option.
- Use an alternative packaging tool: If PyInstaller is not providing the desired level of size optimization, you can consider using alternative packaging tools like cx_Freeze or py2exe.
By incorporating these optimizations, you can effectively reduce the size of the executable created with PyInstaller.
How to create a portable executable with pyinstaller?
To create a portable executable with pyinstaller, follow these steps:
- Install PyInstaller: You can install pyinstaller using pip in your terminal:
1
|
pip install pyinstaller
|
- Navigate to your Python script: Open your terminal and navigate to the directory where your Python script is located.
- Create the Portable Executable: Run the following command in your terminal to create the portable executable:
1
|
pyinstaller --onefile yourscript.py
|
Replace yourscript.py with the name of your Python script.
- Find the Executable: After running the command, PyInstaller will create a dist directory in your current directory. Inside the dist directory, you will find the portable executable file with the same name as your script.
Your portable executable is now created and can be run on any Windows machine without the need to install Python or any dependencies.
