PyInstaller is a powerful and widely used tool in Python for creating executable applications. However, it is common to face the “Imported Module Not Found” error while using this tool. This error often leaves developers puzzled and uncertain about how to fix it.

What causes the “Imported Module Not Found” error?

The PyInstaller error “Imported Module Not Found” occurs when a module that is imported is not recognized by the tool when creating the executable file. One of the main reasons why this issue arises is due to the complex nature of Python code and its dependency on external modules.

How to fix the “Imported Module Not Found” Error

Option 1: Adding Missing Modules to PyInstaller

If PyInstaller does not recognize your dependency, you should add it to the tool. This can be done by running the command “pyinstaller –hidden-import=[module_name] []”. This approach can be useful for applications with fewer external dependencies.

Option 2: Add Dependencies Manually

If option 1 does not work, you can manually add dependencies to PyInstaller by editing the “.spec” file. This file contains lists of modules PyInstaller uses when building an executable package. After adding the missing module, run the command “PyInstaller [your_script.spec]”.

Option 3: Using PyInstaller Hooks

If your application has many dependencies or external modules, using the PyInstaller hooks option might be a better solution. PyInstaller hooks are scripts that serve as pre-processors to identify and bundle third-party code into the generated executable file. To use them, create a new file in your project’s directory named “hooks” and save your hooks within this file. Then, run the command “pyinstaller []” to test if the error is resolved.

Comparison Table

Option Pros Cons
Adding Missing Modules to PyInstaller Easy to use Limited to applications with few dependencies
Add Dependencies Manually Requires some coding knowledge Time-consuming for applications with many external modules
Using PyInstaller Hooks Ideal solution for complex applications with multiple dependencies Requires good knowledge of PyInstaller hooks


The “Imported Module Not Found” PyInstaller error can cause frustration for developers. The solutions presented above provide effective ways to fix this issue. The best option varies depending on the size and complexity of the application. Regardless of the chosen approach, it is essential to maintain a comprehensive list of dependencies to avoid future errors.

Future Considerations

Although PyInstaller is a powerful tool, these steps might not be sufficient for large applications with significant dependencies. If you continue to face issues, consider using Docker-based workflows or other package managers like Anaconda to create an isolated environment. This makes it easier to package complex applications and resolve dependency issues.

When encountering the PyInstaller Error: Imported Module Not Found, developers may have several questions in mind. Here are some frequently asked questions and their corresponding answers:

  1. What causes the PyInstaller Error: Imported Module Not Found?

    The PyInstaller Error: Imported Module Not Found occurs when the PyInstaller package is unable to locate a module that is imported by the main script or any of its dependencies. This can happen when the module is not installed properly or when there is a typo or error in the import statement.

  2. How can I fix the PyInstaller Error: Imported Module Not Found?
    • Check if the module is installed correctly and is accessible from the environment where the script is being run.
    • Ensure that the import statement is correct and has no typos or errors.
    • Add the module to the PyInstaller package using the –hidden-import flag.
    • Manually specify the path to the module in the PyInstaller spec file.
  3. What is the –hidden-import flag in PyInstaller?

    The –hidden-import flag in PyInstaller is used to add a module that is not explicitly imported by the main script or any of its dependencies. This is useful for cases where a module is imported dynamically at runtime or when PyInstaller is unable to detect the module automatically.

  4. How can I manually specify the path to the module in the PyInstaller spec file?

    To manually specify the path to the module in the PyInstaller spec file, open the spec file in a text editor and add the path to the module in the Analysis section. For example:

    ...a = Analysis([''],             pathex=['/path/to/script'],             binaries=[],             datas=[],             hiddenimports=['module'],             hookspath=[],             runtime_hooks=[],             excludes=[],             win_no_prefer_redirects=False,             win_private_assemblies=False,             cipher=None,             noarchive=False)a.datas += [('path/to/module', 'path/to/module')]...
