Custom visual in Power BI using Python

问题

I am trying to replicate this for Python, but cannot find any answer:

Is it possible to use R Plotly library in R Script Visual of Power BI?

or :

Just to be a little more specific: How can I change the offered solution to work with script.py rather than script.R

Any help is highly appreciated.

I have found that in this folder there is a file called capabilities.json, so I assume this is one part of the solution:

  "script": {
      "scriptProviderDefault": "R", ###I guess this needs to be changed to Py
      "scriptOutputType": "html",
      "source": {
        "objectName": "rcv_script",# not sure about this
        "propertyName": "source"
      },
      "provider": {
        "objectName": "rcv_script",# not sure about this
        "propertyName": "provider"
      }
    }

And also after removing referencing dependecies.json in this project, and after building and importing this to Power BI, I got this error

 Error Message:
 An exception of type System.ArgumentException occured.
