ModuleNotFoundError: No module named ‘traitlets’ error occurs when the “Python interpreter cannot find the library traitlets because you haven’t installed.”

To fix the ModuleNotFoundError: No module named ‘traitlets’, the easiest way is to install the “traitlets” module. The traitlets package is “used to manage configurable attributes of classes”, often used in IPython, Jupyter, and related projects.

Here’s how you can install the traitlets package:

Solution 1: Installing the traitlets module

Using pip

pip install traitlets

Using conda (if you’re using an Anaconda environment):

conda install traitlets

After installing the package, you can import it into your code without errors.

Ensure you use the correct Python environment where traitlets is installed, primarily if you work with virtual environments or have multiple Python installations on your system.

If you are working in a Jupyter Notebook, you might need to restart the kernel after installing the package to make it available.

Once you have installed the traitlets module, you can import it without errors.

import traitlets

If you are still getting the error after installing the traitlets module, you may have installed the module in a different directory.

Solution 2: Fixing the module path

You can check the directory where the traitlets module is installed by running the following command in your terminal:

pip show traitlets

This command will show you the location of the traitlets module.

Once you have found the location of the traitlets module, you can add the directory to your Python path. You can do this by adding the following line to your .bashrc file:

export PYTHONPATH=$PYTHONPATH:/path/to/traitlets/module

This line will add the directory /path/to/traitlets/module to your Python path.

I hope this will fix the issue!
