Importerror Attempted Relative Import no Known Parent Package

You might encounter the dreaded “ImportError: Attempted Relative Import with No Known Parent Package” error when working with Python. This error message can be confusing for language beginners. It means your import statements and project package structure need to be corrected.

This issue can result from faulty package structure, missing files, or improper import statements. This error demands knowledge of Python’s import mechanism and package organization.

How to Fix the Error

The “ImportError: Attempted Relative Import with No Known Parent Package” error can be a roadblock in your Python projects, but fear not! You can employ several strategies to resolve this issue and restore the smooth functioning of your code. Let’s explore these solutions one by one:

Make Sure the Module is Part of a Package

Packages are the cornerstone of Python’s modular programming approach. This error indicates that your module needs to be correctly packaged. Check if the module is in a package directory with a file. This file tells Python to treat the directory as a package.

Add an Empty File to the Package Directory.

A missing file in your package directory may cause the “ImportError” issue. Python must identify the directory as a package even if the file is empty. Create an empty file in the module’s package directory.

Add the Package Directory to the Python Path

Python searches for modules to import in specific locations defined by its sys.path list. Python can only discover your modules if your package path is in this list. To fix this, add your package directory path to sys.path. More elegant methods exist, and it’s best to structure your project properly to prevent this workaround.

Use Absolute Imports

While relative imports can be useful, they can lead to confusion and errors, especially in larger projects. Consider using absolute imports instead. Absolute imports specify the full path of the module or package you want to import, starting from the project’s root directory. This eliminates any ambiguity about which package should be used as the reference point.

Other Ways to Fix the Error

While the solutions mentioned earlier can be highly effective in resolving the “ImportError: Attempted Relative Import with No Known Parent Package” error, there are additional approaches you can consider. Depending on your project’s structure and complexity, these alternative methods might provide the solution you need:

Use the if __name__ == “__main__”: Guard

When working with modules intended to be imported and executed as standalone scripts, using the if __name__ == “__main__”: guard can be beneficial. This guard ensures that the code within it is only executed when the script is run directly and not when it’s imported as a module. This helps avoid import errors due to circular imports or incorrect reference points.

Virtual Environments

Creating a virtual environment for your project can positively impact avoiding import-related errors. Virtual environments isolate your project’s dependencies from the global Python environment, preventing conflicts and ensuring your project’s packages are properly organized. This can indirectly help resolve import errors by promoting cleaner package structures.

Refactor Using IDE Tools

Many IDEs have tools for refactoring and optimising code. These tools can quickly identify and fix import issues, missing files, and relative imports. Refactoring code automatically saves time and ensures best practices.

By exploring these alternative methods, you expand your strategies to combat the “ImportError” error and enhance your Python programming experience.

Solutions to “ImportError: Attempted Relative Import with No Known Parent Package” Error

Make Sure the Module is Part of a PackageEnsure that the module is located within a package directory and the package contains an file.
Add an Empty File to the Package DirectoryCreate an empty file in the package directory to signify that it’s a package.
Add the Package Directory to the Python PathAppend the path to your package directory to the sys.path list to make the package discoverable.
Use Absolute ImportsUtilize absolute imports to explicitly specify the full path of the module to be imported.

Avoiding the Error in the First Place

While knowing how to fix the “ImportError: Attempted Relative Import with No Known Parent Package” error is essential, preventing the error from occurring in the first place is even better. By adhering to best practices and following certain guidelines, you can set up your Python projects for success and avoid stumbling upon this error altogether.

Package Structure

Organize related modules into packages and sub-packages and ensure each package directory contains an file. This initial groundwork can prevent import errors down the line.


While relative imports can be useful, especially within a package, relying primarily on absolute imports can make your code more robust. Absolute imports provide a clear path to the module you want to import, eliminating ambiguity about which package is the reference point.

Avoid Circular Dependencies

Circular dependencies occur when two or more modules depend on each other directly or indirectly. These can lead to import errors and often need better design. To prevent them, design your codebase with the separation of concerns in mind and refactor as necessary to break circular dependencies.

 Virtual Environments

Using virtual environments not only keeps your project dependencies isolated but also encourages cleaner package structures. Each project can have its virtual environment, reducing the likelihood of import errors caused by package conflicts.

 Testing and Code Reviews

Regularly testing your code and conducting thorough code reviews can help catch potential import errors early. Peer reviews can provide fresh perspectives and identify issues that might go unnoticed.

 Best Practices

Python’s community is active and vibrant, sharing best practices and coding conventions. Staying updated with these practices can guide you toward writing cleaner and more maintainable code, reducing the chances of import-related errors.

The module is Part of a Package.

Suppose you have a package named ‘mypackage’ and a module named ‘mymodule’ inside it.

# Your project structure:

# myproject/

# ├── mypackage/

# │ ├──

# │ └──

# └──

# In '', you want to import 'mymodule' properly:

# Correct way to import:

from mypackage import mymodule

# This ensures 'mymodule' is part of the 'mypackage' package.

an Empty File to the Package Directory

# To make sure your package is recognized, create an empty '' file in the package directory:

# myproject/

# ├── mypackage/

# │ ├── # Create this empty file

# │ └──

# └──

# Now, Python will treat 'mypackage' as a package.

Package Directory to the Python Path

# To add the package directory to the Python path, you can do this in your script (e.g., ''):

import sys


# Now, Python will find your package and its modules when importing.


Navigating the realm of Python programming comes with its challenges, and the “ImportError: Attempted Relative Import with No Known Parent Package” error can puzzle even seasoned developers. However, armed with the knowledge and strategies discussed in this article, you must be better equipped to overcome this error and maintain a more efficient and organized codebase.

 While fixing errors is crucial, avoiding them in the first place is even more beneficial. By adopting best practices, planning your project’s package structure meticulously, and staying informed about the latest developments in Python, you can set yourself up for success from the outset.

Python’s versatility and extensive community support make it an exciting language. By mastering the art of importing modules and packages, you’ll overcome hurdles like the “ImportError” error and elevate your overall Python programming skills.
