ModuleNotFoundError: No module named ‘IPython’

In Python, ModuleNotFoundError: No module named ‘IPython’ error occurs if we try to import the ‘ipython‘ module without installing the package or if you have not installed it in the correct environment.

In this tutorial, let’s look at installing the ipython module correctly in different operating systems and solve ModuleNotFoundError: No module named ‘IPython’ error.  

What is ModuleNotFoundError: No module named ‘IPython’?

There are various reasons why we get the ModuleNotFoundError: No module named ‘IPython’ error

  • Trying to use the module- without installing the ipython package.
  • If the IDE is set to the incorrect version of the Python/Python interpreter.
  • You are using the virtual environment and the ipython module is not installed inside a virtual environment
  • Installing the ipython package in a different version of Python than the one which is used currently.
  • Declaring a variable name as the module name(ipython)

If you are getting an error installing pip, checkout pip: command not found to resolve the issue.

How to fix ModuleNotFoundError: No module named ‘IPython’?

ipython is not a built-in module (it doesn’t come with the default python installation) in Python; you need to install it explicitly using the pip installer and then use it.  

IPython provides a rich toolkit to help you make the most of using Python interactively. Its main components are:

  • A powerful interactive Python shell.Screenshot Of Ipython 6.0
  • Jupyter kernel to work with Python code in Jupyter notebooks and other interactive frontends.

We can fix the error by installing the ‘ipython‘ module by running the pip install ipython command in your terminal/shell.

We can verify if the package is installed correctly by running the following command in the terminal/shell.

This will provide the details of the package installed, including the version number, license, and the path it is installed. If the module is not installed, you will get a warning message in the terminal stating WARNING: Package(s) not found: ipython.

pip show ipython

Output

Name: ipython
Version: 8.4.0
Summary: IPython: Productive Interactive Computing
Home-page: https://ipython.org
Author: The IPython Development Team

Requires: backcall, prompt-toolkit, decorator, pickleshare, colorama, traitlets, matplotlib-inline, jedi, pygments, stack-data, setuptools

Solution 1 – Installing and using the ipython module in a proper way

Based on the Python version and the operating system you are running, run the relevant command to install the ipython module.

# If you are using Python 2 (Windows)
pip install ipython

# if you are using Python 3 (Windows)
pip3 install ipython

# If the pip is not set as environment varibale PATH
python -m pip install ipython

# If you are using Python 2 (Linux)
sudo pip install ipython

# if you are using Python 3 (Linux)
sudo pip3 install ipython

# In case if you have to easy_install
sudo easy_install -U ipython

# On Centos
yum install ipython

# On Ubuntu
sudo apt-get install ipython

# If you are installing it in Anaconda 
conda install -c anaconda ipython

Once you have installed the ipython module, we can now import it inside our code and use it as shown below.

Ensure that 'I' and 'P' characters are in the capital while importing the module as demonstrated.

import IPython

print(IPython.__version__)

Output

8.4.0

Solution 2 – Verify if the IDE is set to use the correct Python version

If you are still getting the same error even after installing the package, you can verify if the IDE you are using is configured with the correct version of the Python interpreter.

For Eg:- In the case of Visual Studio Code, we can set the Python version by pressing CTRL + Shift + Por ( + Shift + P on Mac) to open the command palette.

Once the command palette opens, select the Python interpreter and select the correct version of Python and also the virtual environment(if configured) as shown below.

Solution 3 – Installing ipython inside the virtual environment

Many different IDEs like Jupyter Notebook, Spyder, Anaconda, or PyCharm often install their own virtual environment of Python to keep things clean and separated from your global Python.

If you are using VS Code, then you can also create a virtual environment, as shown below.

In the case of virtual environments, you need to ensure that the ipython module needs to be installed inside the virtual environment and not globally.

Step 1: Create a Virtual Environment. If you have already created a virtual environment, then proceed to step 2.

Step 2: Activate the Virtual Environment

Step 3: Install the required module using the pip install command

# Create a virtual Environment
py -3 -m venv venv

# Activate the virtual environment (windows command)
venv\Scripts\activate.bat

# Activate the virtual environment (windows powershell)
venv\Scripts\Activate.ps1

# Activate the virtual environment (Linux)
source venv/bin/activate

# Install ipython inside the virtual environment
pip install ipython

Solution 4 – Ensure that a module name is not declared name a variable name.

Last but not least, you may need to cross-check and ensure that you haven’t declared a variable with the same name as the module name.

You should check if you haven’t named any files as IPython.py as it may shadow the original ipython module.

If the issue is still not solved, you can try removing the package and installing it once again, restart the IDE, and check the paths to ensure that packages are installed in the correct environment path and Python version.

Conclusion

The ModuleNotFoundError: No module named ‘IPython’ error occurs when we try to import the ‘ipython‘ module without installing the package or if you have not installed it in the correct environment.

We can resolve the issue by installing the ipython module by running the pip install ipython command. Also, ensure that the module is installed in the proper environment in case you use any virtual environments, and the Python version is appropriately set in the IDE that you are running the code.
