Handler-python: 'module' object has no attribute 'model_to_json_grid_check'

Having trouble when I tranfer the pollination rhino model into grasshopper. Help is much appreciated.


Hi @kkt,

The import from Rhino has been successful. The error that you see is an error for a missing handler. This is happening because your Ladybug Tools installation is older than what the recipe expects. You can solve this by updating the LBT installation. Any of these methods should do it for you:

  • Use the Versioner component inside Grasshopper and update your installation.
  • Install the latest version of the Grasshopper component.
  • Install the developer version of the Rhino component.

Thank you Mostapha. Solved.
