使用Python在Power BI中自定义可视化

Question

我正试图为Python复制这一点，但找不到任何答案：

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

或：

更具体地说： 如何将提供的解决方案更改为使用script.py而不是script.R

非常感谢您的帮助

我发现在这个文件夹中有一个名为capabilities.json的文件，所以我假设这是解决方案的一部分：

  "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"
      }
    }

在这个项目中删除referencedependecies.json之后，在构建并导入到powerbi之后，我得到了这个错误
