Alteryx 2024.1.1.17 : Tableau Output not working, numpy error

Hello all,

I have this error message when trying to create a datasource on my Tableau

Error: Tableau Output (1): Traceback (most recent call last):

IMPORTANT: PLEASE READ THIS FOR ADVICE ON HOW TO SOLVE THIS ISSUE!

Importing the numpy C-extensions failed. This error can happen for
many reasons, often due to issues with your setup or how NumPy was
installed.

We have compiled some common reasons and troubleshooting tips at:

    https://numpy.org/devdocs/user/troubleshooting-importerror.html

Please note and check the following:

  * The Python version is: Python3.10 from "C:\Program Files\Alteryx\bin\AlteryxEngineCmd.exe"
  * The NumPy version is: "1.19.1"

and make sure that they are the versions you expect.
Please carefully study the documentation linked above for further help.

Original error was: No module named 'numpy.core._multiarray_umath'

Here the workflow :

I do think it's due to the python update and will try to find how to solve it and post the solution. Any other helpful hints?

Best regards,

Simon

And now it works !

However I'm pretty surprised the former version is still there... should

Hi @simonaubert_bd. Your suspicion sounds correct: it appears the version of the numpy you have installed does not have the ".core.multiarray.umath" package included. This is likely due to it being outdated. Upgrading the numpy version is relatively simple, but I expect you to face issues do to updating it in the location the Tableau output tool is specifically looking at. This is because the sitepackages folder where numpy is stored is within the tableau directory, not the global Python directory.

Id take the path given in the error message and insert it where "path" is in into the following line and run in command prompt (admin access):

/path/ -m pip install --upgrade numpy

so it looks like

/C:/Users/saubert/AppData/Roaming/Alteryx/Tools/Tableau_v1.1.0_venv/Lib/site-packages/numpy/core -m pip install --upgrade numpy

you might have to try this without the "/C:".

Give this a shot and let me know if this fixes it! Regards - Rhys

Hello @Rhys_Cooper Thanks for your message. In the meantime, I found another (and easier solution) to my issue : using the marketplace, download the new version of the tool.

However, I will keep your solution for my custom tools that weren't updated/available on the marketplace.

Best regards,

Simon

Many ongoing issues... I was able successfully connect it and run with ONE output source after multiple attempts . However, adding more than 2 outputs in the same workflow creates additional challenges. No solution at the moment and we are trying to engage Alteryx support team... I am using 2021.4.2 version of Alteryx and the latest "Tableau Output" v1.4.1

Thanks
