ModuleNotFoundError: No module named 'IPython' in Python #

The Python "ModuleNotFoundError: No module named 'IPython'" occurs when we forget to install the ipython module before importing it or install it in an incorrect environment. To solve the error, install the module by running the pip install ipython command.

no module named ipython

Open your terminal in your project's root directory and install the ipython module.

shell
# ๐Ÿ‘‡๏ธ in a virtual environment or using Python 2 pip install ipython # ๐Ÿ‘‡๏ธ for python 3 (could also be pip3.10 depending on your version) pip3 install ipython # ๐Ÿ‘‡๏ธ if you get permissions error sudo pip3 install ipython # ๐Ÿ‘‡๏ธ if you don't have pip in your PATH environment variable python -m pip install ipython # ๐Ÿ‘‡๏ธ for python 3 (could also be pip3.10 depending on your version) python3 -m pip install ipython # ๐Ÿ‘‡๏ธ for Anaconda conda install -c anaconda ipython

After you install the ipython package, try importing it like:

main.py
from IPython.display import Image import IPython print(Image) print(IPython.__version__)

Notice the casing is IPython - very important because imports are case sensitive.

Make sure to capitalize the I and P characters when importing the module.

The Python error "ModuleNotFoundError: No module named 'IPython'" occurs for multiple reasons:

  1. Not having the ipython package installed by running pip install ipython.
  2. Installing the package in a different Python version than the one you're using.
  3. Installing the package globally and not in your virtual environment.
  4. Your IDE running an incorrect version of Python.
  5. Naming your module ipython.py which would shadow the official module.
  6. Declaring a variable named ipython which would shadow the imported variable.

If the error persists, get your Python version and make sure you are installing the package using the correct Python version.

shell
python --version

get python version

For example, my Python version is 3.10.4, so I would install the ipython package with pip3.10 install ipython.

shell
pip3.10 install ipython # ๐Ÿ‘‡๏ธ if you get permissions error use pip3 (NOT pip3.X) sudo pip3 install ipython

Notice that the version number corresponds to the version of pip I'm using.

If the PATH for pip is not set up on your machine, replace pip with python3 -m pip:

shell
# ๐Ÿ‘‡๏ธ make sure to use your version of Python, e.g. 3.10 python3 -m pip install ipython

If the "No module named 'IPython'" error persists, try restarting your IDE and development server / script.

You can check if you have the ipython package installed by running the pip show ipython command.

shell
# ๐Ÿ‘‡๏ธ check if you have ipython installed pip3 show ipython # ๐Ÿ‘‡๏ธ if you don't have pip setup in PATH python3 -m pip show ipython

The pip show ipython command will either state that the package is not installed or show a bunch of information about the package, including the location where the package is installed.

If the package is not installed, make sure your IDE is using the correct version of Python.

If you have multiple Python versions installed on your machine, you might have installed the ipython package using the incorrect version or your IDE might be setup to use a different version.

For example, In VSCode, you can press CTRL + Shift + P or (โŒ˜ + Shift + P on Mac) to open the command palette.

Then type "Python select interpreter" in the field.

python select interpreter

Then select the correct Python version from the drop down menu.

select correct python version

Your IDE should be using the same version of Python (including the virtual environment) that you are using to install packages from your terminal.

If you are using a virtual environment, make sure you are installing ipython in your virtual environment and not globally.

You can try creating a virtual environment if you don't already have one.

shell
# ๐Ÿ‘‡๏ธ use correct version of Python when creating VENV python3 -m venv venv # ๐Ÿ‘‡๏ธ activate on Unix or MacOS source venv/bin/activate # ๐Ÿ‘‡๏ธ activate on Windows (cmd.exe) venv\Scripts\activate.bat # ๐Ÿ‘‡๏ธ activate on Windows (PowerShell) venv\Scripts\Activate.ps1 # ๐Ÿ‘‡๏ธ install ipython in virtual environment pip install ipython

Your virtual environment will use the version of Python that was used to create it.

If the error persists, make sure you haven't named a module in your project as ipython.py because that would shadow the original ipython module.

You also shouldn't be declaring a variable named ipython as that would also shadow the original module.

If the error is not resolved, try to uninstall the ipython package and then install it.

shell
# ๐Ÿ‘‡๏ธ check if you have ipython installed pip3 show ipython # ๐Ÿ‘‡๏ธ if you don't have pip setup in PATH python3 -m pip show ipython # ๐Ÿ‘‡๏ธ uninstall ipython pip3 uninstall ipython # ๐Ÿ‘‡๏ธ if you don't have pip setup in PATH python3 -m pip uninstall ipython # ๐Ÿ‘‡๏ธ install ipython pip3 install ipython # ๐Ÿ‘‡๏ธ if you don't have pip setup in PATH python3 -m pip install ipython

Try restarting your IDE and development server / script.

You can also try to upgrade the version of the ipython package.

shell
pip3 install ipython --upgrade # ๐Ÿ‘‡๏ธ if you don't have pip setup in PATH python3 -m pip install ipython --upgrade
If the error persists, I would suggest watching a quick video on how to use Virtual environments in Python.
