Your team is deeply involved in numerous machine learning projects, with a significant focus on TensorFlow. Recently, you've developed an NLP model that performs exceptionally well and is nearing production deployment. To showcase this model to managers and stakeholders, you're preparing a demo that highlights its text and sentiment interpretation capabilities. Anticipating questions about how software can interpret human emotions, you aim to present an interactive demonstration with insightful interference. The demo should not only display the model's predictions but also provide a clear explanation of how these predictions are made, including the ability to test the model with custom inputs. Given the need for a tool that supports interactive exploration, model explanation, and the testing of NLP models, which of the following tools would be most suitable for this purpose?
