We’re happy to announce the beta release of TabPy, a new API that enables evaluation of Python code from within a Tableau workbook.
When you use TabPy with Tableau 10.1, you can define calculated fields in Python, thereby leveraging the power of a large number of machine-learning libraries right from your visualizations.
This new Python integration in Tableau enables powerful scenarios. For example, it takes only a few lines of Python code to get the sentiment scores for reviews of products sold at an online retailer. Then you can explore the results in many ways in Tableau.
You might filter to see just the negative reviews and review their content to understand the reasons behind them. You might to get a list of customers to reach out to. Or you might visualize overall sentiment changes over time.
Other common business scenarios include:
You can easily install the TabPy server on your computer or on a remote server. Configure Tableau to connect to this service by entering the service URL and port number under Help > Settings and Performance > Manage External Service Connection in Tableau Desktop. Then you can use Python scripts as part of your calculated fields in Tableau, just as you’ve been able to do with R since Tableau 8.1.
TabPy uses the popular Anaconda environment, which comes preinstalled and ready to use with many common Python packages including scipy, numpy, and scikit-learn. But you can install and use any Python library in your scripts.
If you have a team of data scientists developing custom models in your company, TabPy can also facilitate sharing those models with others who want to leverage them inside Tableau via published model.
Once published, all it takes to run a machine-learning model is a single line of Python code in Tableau regardless of model type or complexity. You can estimate the probability of customer churn using logistic regression, multi-layer perceptron neural network, or gradient boosted trees just as easily by simply passing new data to the model.
Using published models has several benefits. Complex functions become easier to maintain, share, and reuse as deployed methods in the predictive-service environment. You can improve and update the model and code behind the endpoint while the calculated field keeps working without any change. And a dashboard author does not need to know or worry about the complexities of the model behind this endpoint.
Together, Tableau and Python enable many more advanced-analytics scenarios, making your dashboards even more impactful. To learn more about TabPy and download a copy, please visit our GitHub page. Give TabPy a try, and let us know what you think at firstname.lastname@example.org.
