If you’re new to Python, you may encounter the “ImportError: attempted relative import with no known parent package” error. This error message usually appears when you’re trying to import a module from a parent folder using relative imports. In this comprehensive guide, we’ll provide you with various solutions to fix this error, even if you’re a tech noob. So, let’s get started!
What Causes this Error?
According to a post on Reddit1, the error message “ImportError: attempted relative import with no known parent package” means that your “test” folder does not have a parent package. So, you can’t import something from the parent folder using relative imports.
How to Solve this Error?
Now, let’s dive into the various solutions to fix this error.
Option 1: Get Rid of “from”
One solution that worked for someone on Reddit1 is to get rid of “from” and use an absolute import instead. For example, instead of writing:
javascript
Copy code
[from .. import my_module]
You can write:
arduino
Copy code
[import my_module]
This solution should work if you’re importing a module from a parent folder.
Option 2: Make an Actual Package
Another solution is to make an actual package instead of just having a folder with modules. To do this, you need to create a file named “setup.py” in the parent folder and add the following code:
arduino
Copy code
[from setuptools import setup, find_packages]
[setup
name=’my_package’,
version=’0.1′,
packages=find_packages(),
install_requires=[],]
After that, you need to install your package by running the following command:
arduino
Copy code
python setup.py install
Then, you can use absolute imports to import your modules. For example, instead of writing:
javascript
Copy code
[from .. import my_module]
You can write:
javascript
Copy code
[from my_package import my_module]
Option 3: Changing the Caller Program (runcode.py)
If you have a “runcode.py” file in your project, you can modify it to add the parent folder to the Python path. Here’s an example:
javascript
Copy code
[import sys]
[sys.path.insert(0, ‘../’)]
[from my_module import my_function]
Conclusion:
In conclusion, the “ImportError: attempted relative import with no known parent package” error can be fixed by using various solutions, such as getting rid of “from” and using absolute imports, making an actual package, or modifying the caller program. We hope that this ultimate guide provides you with the necessary steps to solve this error, regardless of your level of expertise in Python. Don’t let this error discourage you from continuing your Python projects, and apply these solutions to overcome it. Happy coding!
