RuntimeError: LoadFailed: 'Load failed: code() takes at most 14 arguments (15 given) about tabpy HOT 5 CLOSED

Hi Brit,
Tableau passes the objects as Python lists. Does it work when you delete the [ ] around testing_data object in your predictSpam function?

Thanks,

Hi Brit,
Can you make sure your TabPy server and IPython workbook you're using have the same version of Python? The piece of code that is triggered here takes different number of arguments in Python 2.x vs 3.x. That is my first guess on why this might be happening. If that's not the issue, I will dig deeper.

Thanks,

That was part of the issue - thank you!

When it comes to passing data from Tableau to the function it doesn't work and I'm wondering if it has to do with data types. The use case is simple - pass text via a parameter in Tableau to the model and return 0 or 1 (cast as a string).

In my function, I originally returned a numpy array while in Tableau I was using SCRIPT_STR. I thought perhaps that since it could take multiple strings and return a list of results that I could simply return 1 since I'm passing one argument in Tableau. I tried so resolve that and tested it in my notebook to ensure the data I was returning to Tableau was a string.

In Tableau, my calculation is:

The parameter:

The error it returns:

Is there something I am missing with how the data is passed in the string parameter in Tableau? Would it not be read as a string by the function? Or, is there a different way I need to deploy my code? I think another reason why it may not work is because I'm only deploying the function but it calls something earlier in my notebook. I was trying to save a trained model versus needing to retrain each time.

I've verified that TabPy is running and the function endpoint exist. Any recommendations?

I am glad it worked.
