How to Fix "Jupyter Notebook Shows 'ImportError: No module named' Error"

The ImportError: No module named error in Jupyter Notebook occurs when Python is unable to find a module that you’re trying to import.

This is often due to either the module not being installed in the correct environment or the wrong Python environment being used in the notebook.

The first thing to check is whether the module is installed in the Python environment used by Jupyter.

To do this, run !pip list within the notebook to list installed packages.

If the module is not listed, use !pip install <module_name> to install it.

If you are using Anaconda or a virtual environment, make sure that Jupyter is running in the correct environment.

You can install the necessary module in the active environment by using conda install <module_name> or pip install <module_name>.

If the module is installed but still shows the ImportError, it could be that the kernel you’re using does not correspond to the correct Python environment.

In this case, change the kernel to the appropriate environment by navigating to Kernel > Change kernel and selecting the right environment.

Additionally, you can check which environment Jupyter is using by running import sys; print(sys.executable) in a cell.

This will print the path of the current Python interpreter.

Ensure that the interpreter corresponds to the environment where the module is installed.

In some cases, it might be necessary to install the kernel for the specific environment using python -m ipykernel install --user --name <env_name> --display-name **<display_name>**.

If you’re using a Python virtual environment, make sure that it’s activated before starting Jupyter Notebook.

Running source <env_name>/bin/activate in the terminal ensures that the right environment is active.

By following these steps, you should be able to resolve the ImportError and correctly import modules in Jupyter Notebook.
