Hi guys,
Trying to run kedro viz, and I am getting some strange errors like below:

Could you please let us know if there were any changes to the installations or this is a different project. Thank you
Not that I know. It still works for kedro run, everything is fine but viz complains for some reason. That class inherits AbstractDataset. Not sure why it says that
Do you have a custom hook helping in some way ? kedro viz run does not include hooks by default. Can you try kedro viz run --include-hooks ?
I tried that, it still didn't work. I have no clue why this is happening. I don't have complex hooks, just to parse certain columns of dataframe in the data. 🤷
Hi @Fazil Topal, Is it possible to clear cache and re-install kedro-viz ? Based on the logs it pretty much points to the dataset projx.models.llm.LLM being a list instead of AbstractDataset instance. If possible, could you please open a bug ticket with some reproducible snippet. Appreciate your patience. Thank you
