This article will show you how to solve the error “modulenotfounderror: no module named ‘imblearn’” in Python.
Aside from that, we will also discuss with you the meaning of “imblearn.”
What does this error indicate?
The modulenotfounderror: no module named ‘imblearn’ shows that the imblearn module is not installed in the Python environment.
With this kind of issue, you do not need to panic, as it is easy to resolve, and we’re here to guide you with this one.
What is an imblearn?
‘Imblearn‘ (imbalanced–learn) is an open-source, third-party library that offers resources for handling imbalanced classes.
This needs to be separately installed using a pip.
As said above, the error occurs when the module is not installed in the Python environment.
And, to resolve this error, you need to install the imblearn library pip.
Here’s a simple guide on how to solve the error “no module named ‘imblearn’.”
How to solve the No Module Named ‘imblearn’ in Python
Time needed: 1 minute
The following are the steps on how to resolve the error message modulenotfounderror: no module named ‘imblearn’ in Python.
- Check if the imblearn module is installed.
The first step is to check if the imblearn module is installed in your Python environment.
To check, open the cmd or command prompt, then type the command:
The command “pip list” will show you the list of installed modules in your Python environment.
Moving on, if the imblearn module is not found, move to the next step. - Install ‘imblearn’.
If the imblearn module is not found in your Python environment, install it.
To install, input the command:
The command “pip install imblearn” will download and install the latest version of the imblearn module in Python.
Note: Once installed, try to run your program again. And, if an error still exists, try the following:
- Check if the imblearn module is installed in the same environment that you’re currently using.
To do so, input this command:
import sys
print(sys.path)
- If it’s in the same path but the error still exists, try to upgrade the imblearn module.
To do so, input the following command:
pip install –upgrade imblearn
The command “pip install –upgrade imblearn” will upgrade the imblearn module to its latest version.
If your imblearn module is already the latest version, this will come out: “requirement already satisfied.”
Install ‘imbalanced-learn’ on macOS or Linux
The following are the steps on how to install imbalanced-learn on macOS or Linux:
1. First, open the terminal.
2. Next, input the command: pip install imbalanced-learn.
3. Lastly, click the enter key.

python -mIt will look like this:
python -m pip install imbalanced-learnHowever, if you get a permissions error, use the command:
sudo pip install imbalanced-learn.Frequently Asked Questions
What is Python ModuleNotFoundError and what causes it?
ModuleNotFoundError (a subclass of ImportError) is raised when Python cannot find the module you tried to import. Common causes: the package isn’t installed (pip install missing), wrong virtual environment activated, typo in module name, or Python can’t find your local module on the import path. The error message names exactly which module is missing.
How do I fix ‘ModuleNotFoundError: No module named X’?
Run pip install X first. If that succeeds but you still get the error, check which Python you’re using (which python OR python –version) vs which pip (which pip OR pip –version), they must match. Common gotcha: pip points to system Python 3.9 but you’re running python3.11 in a venv. Inside the venv, use python -m pip install X to be sure pip matches the active Python.
Why does my code work in one environment but not another?
Different Python versions or different installed packages. To diagnose: pip freeze > requirements.txt on the working environment, then pip install -r requirements.txt on the broken one. Use virtualenv (python -m venv venv) or conda for every project to avoid system-wide package collisions.
Is ModuleNotFoundError the same as ImportError?
ModuleNotFoundError is a subclass of ImportError added in Python 3.6. It specifically means ‘no such module exists.’ Plain ImportError covers a wider set: module exists but a name inside it can’t be imported (e.g. ‘cannot import name X from Y’). except ImportError catches both; except ModuleNotFoundError catches only the missing-module case.
Where can I find more ModuleNotFoundError fixes?
Browse the ModuleNotFoundError reference hub for 198+ specific module fixes (TensorFlow, Flask, Django, pandas, numpy, etc.). For related issues see ImportError. For broader Python setup see Python Tutorial hub.
Conclusion
In conclusion, the error “modulenotfounderror: no module named ‘imblearn’” can be easily solved by:
Checking if the imblearn module is installed in your Python environment and, if not, by installing it.
By following the guide above, there’s no doubt that you’ll be able to resolve this error quickly.
We hope you’ve learned something from this.
