It seems that `kedro viz` does not recognise `kedro mlflow`

Question

It seems that `kedro viz` does not recognise `kedro mlflow` matplotlib plots while it does appear as a data node in the `kedro viz` dashboard the content cannot be examined as a usual matplotlib png ```example plot type kedro mlflow io artifacts MlflowArtifactDataSet data set type matplotlib MatplotlibWriter filepath data 08 reporting example plot png versioned true```

It seems correct as per the <https github com Galileo Galilei kedro mlflow tutorial readme|docs> Can you remove versioned true and try it again

Nero Okwa · Answer

< Yolan Honoré Rougé> any thoughts on this

Deepyaman Datta · Answer

< Nero Okwa> would you expect support for `MlflowArtifactDataSet` I ve never tried this but intuitively I wouldn t expect Kedro Viz to support a dataset using `MatplotlibWriter` under the hood

Nero Okwa · Answer

< Deepyaman Datta> Yes Kedro Viz supports but you need add it to your dependencies first

Nero Okwa · Answer

< Yong Bang Xiang> have you added the dataset to your `src requirements txt` file like this ```kedro datasets matplotlib MatplotlibWriter ~=1 1 seaborn~=0 12 1```

Yong Bang Xiang · Answer

yes i have still no luck

Nero Okwa · Answer

Can you share a screenshot of what you are seeing

Yong Bang Xiang · Answer

```example plot type matplotlib MatplotlibWriter filepath data 08 reporting example plot png```

Yong Bang Xiang · Answer

```example plot type kedro mlflow io artifacts MlflowArtifactDataSet data set type matplotlib MatplotlibWriter filepath data 08 reporting example plot png```

How does kedro viz decide what to plot Does it check for the dataset being a ``MatplotlibWriter`` instance

Nero Okwa · Answer

Yes

Yolan Honoré-Rougé · Answer

If yes it explains the issue because kedro mlflow turns it into a ``MlflowMatplotlibWriter`` object under the hood

Nok Lam Chan · Answer

Agree with < Deepyaman Datta> I don t expect kedro viz work for custom dataset as it is inspecting the type of dataset directly < Yolan Honoré Rougé> Does ``Mlflow MatplotlibWriter` exist I did a quick search and couldn t find anything related

Nok Lam Chan · Answer

I think it is more beneficial to turn this into a discussion how we can have a generic support Same goes with the `DataFrame` preview feature Questions 1 Do we want to add support for individual datasets when requested 2 Or can we provide a way that allow user to register their own dataset to be displayed

Yolan Honoré-Rougé · Answer

No actually MlflowArtifactDataSet is a very special dataset which use new toninstantiate class and fake inheritance It modifies object class on the fly

Nok Lam Chan · Answer

Obviously not everything can be supported so we need to consider what can be display For `preview` feature it is less restricted because we inspect `DataFrame` instead of `pandas CSVDataSet` meaning that if user implement their own `pandas MyDataSet` it will still work as long as it returns a DataFrame

Deepyaman Datta · Answer

I think rather than adding support for individual datasets it may make sense to create an interface that datasets can implement to have this support because its a relativrly small set of datasets that would need to support it I d assume That said this is definitely a topic that would require tech design But < Yong Bang Xiang> to close the loop I would say it s the expected behavior that this doesn t currently work however unfortunate

Juan Luis · Answer

gt I think rather than adding support for individual datasets it may make sense to create an interface that datasets can implement to have this support +100 maybe even checking for ` repr png ` method like IPython Jupyter do
