How to Fix "Jupyter Notebook Shows 'ModuleNotFoundError' Error for Pandas"

If you encounter the ModuleNotFoundError for pandas in Jupyter Notebook, it typically means that the pandas package is not installed in the Python environment used by Jupyter.

Pandas is an essential library for data manipulation, so it is crucial to get it working.

Here’s how to resolve this issue: First, confirm that pandas is installed in the correct environment by running !pip list within a notebook cell.

If you don’t see pandas in the list, you’ll need to install it.

Use the following command: !pip install pandas to install it directly from the notebook.

If you’re using a different Python environment (such as Anaconda or a virtual environment), ensure that Jupyter Notebook is running in the correct environment.

You can install pandas in the active environment by using conda install pandas for Anaconda or pip install pandas for a virtual environment.

If the installation is successful but the error persists, ensure that Jupyter Notebook is using the correct kernel.

Sometimes, the notebook may default to a different kernel, which might not have pandas installed.

To change the kernel, go to Kernel > Change Kernel and select the correct environment that has pandas.

You can also check the current Python interpreter being used by running import sys; print(sys.executable) in a cell to verify the active environment.

If needed, install the kernel for your specific environment using python -m ipykernel install --user --name <env_name> --display-name **<display_name>**.

Another solution is to restart the Jupyter Notebook server to ensure that the installed packages are correctly loaded.

Sometimes, after installing a package, the Jupyter environment doesn’t immediately recognize it, and a restart is required to refresh the package list.

By following these troubleshooting steps, you should be able to resolve the ModuleNotFoundError for pandas and use it in your Jupyter Notebook.
