This error occurs because you are trying to import module trafaret, but it is not installed in your python environment.


To install the module, execute the following command in termanal:

 pip install trafaret

To install the module inside Google Colab, Kaggle/Jupyter Notebook or ipython environment, execute the following code line/cell:

 !pip install trafaret

How it works:

pip - is a standard packet manager in python. This program can install missing module in your local development environment or current Google Colab/Kaggle/Jupyter Notebook session.

! - exclamation mark instructs interactive environment to interpret line/cell content as shell command, not as python code. This is needed because pip command should be executed in shell.
