Share. While there are more steps to this and they are show in the referenced jupyter notebook, the important thing is to implement the API that integrates with the rest of Keras training and testing workflow.That is as simple as implementing and update_state that takes in the true labels and predictions, a reset_states that re-initializes . The first step is defining a Python class inheriting from the DOMWidget base class. jupyter nbconvert --Application.log_level=10.

In other words, it's a platform for hosting notebooks on a server with multiple users. The notebook extends the console-based approach to interactive computing in a qualitatively new direction, providing a web-based application suitable for capturing the whole computation process: developing, documenting, and executing code, as well as communicating the results. Jupyter Notebooks are a great tool for research, data science type things, and teaching. nbconvert is a Python library that allows you to convert your Jupyter Notebook into other formats, like HTML, LaTeX and PDF. The issue with your code segment is that my_dict is declared inside the word_count method and then your trying to access it outside the method, where it doesn't have scope.
