TabPy seems really nice. Fully integrated executable Python code from a workbook. Beautiful! Although, the WDC does have a interface for building predictive models, which could come in handy for those analyst not skilled in Python or R.

Thanks Tom for the info, appreciate it.

Hi Prayson,

Thanks for reading and commenting on the WDC I built a while ago

I used my pythonanywhere account to host this WDC prototype as an example on how to connect and demonstrate the possibilities of a Web Data Connector using a ML library (scikit-learn) on the server side. It is not intended to handle sensitive data and I limited the file upload to a few MB.

However the Python code (using the web framework Flask) could preferably be placed and run from a local server or your local machine as long as it can handle http requests. I know when I was testing the WDC locally I connected Tableau to localhost:5000/wdc (5000 = the default port of Flask)

Yes it's true that not all business analysts and business users in need of predictive analytics are fluent in R or Python, but still they can have an excellent understanding of the business objective and the data thus providing valuable input variables for a model.

As demonstrated it works very well using a WDC with a ML library on the server providing predictive analytics in Tableau.

Although, I believe it would be even better if Tableau further developed the analytics capabilities and algorithms natively available in the desktop client. The k-means algorithm for clustering  is a nice addition but additional algorithms in supervised learning would be much appreciated.

All the best

Erik
