Python Tool not loading

[jlabadorf]

I'm trying to implement the Python tool in Alteryx Designer and I am not having any luck with it loading. I click on the tool and enter properties. I get the standard "Jupyter is loading" message which lasts for a minute before going to a blank screen in the properties section. It looks like it is failing to initialize Python. If I choose Production mode, I get an empty textbox, but am unable to input any text or code into that box. This is rather frustrating. I can use the R Tool. I have never initialized Python in Alteryx.

A few things to note: 

1. I tried running as admin, no dice. 

2. I have version of Python installed on my machine which I use for coding and therefore cannot be removed.

I ran the python example and got an output error. I've included it below.

Any help would be appreciated.

Hi @jlabadorf 

Normally in these scenarios I have seen that there was either an error in the installation which prevented certain python dependencies from being installed properly, or there is an IT policy on your machine which may be blocking certain processes/files from being leveraged. In any case, it is probably best to email support@alteryx.com so that they can get it logged for you. You may be able to resolve this by reinstalling as well.

I actually just reinstalled it and it now works. Thanks!

reinstalled Alteryx or python?
