Dataset format not respecting png argument

Hi guys 🙂

I have the following dataset in catalog and it doesn't respect the format: png arg, I guess the whole save_args section of the matplotlib dataset specifically. It doesn't fail, just saves those files as text files instead of png.

Looking at this syntax, do you have a hypothesis why it may be the case?

Based on this section of docs, it should work.

Please verify whether behaviour is the same if you use just PartitionedDataset without MLflowArtifactDataset.
If above works, then ask on #C03RKPCLYGY , because it would be related to kedro-mlflow
Otherwise, let's continue here - might be a bug in Kedro.

Note that matplotlib dataset is kind of a special one, it can take a list or dictionary of output. (Build in partitioning basically).

I've seen people doing that a lot with kedro-mlflow so it should definitely work. Did you have a chance to investigate as suggested above?

Hi !
Unfortunately no, deprioritized this, and I’m achieving what I need by making keys of the dict[str, Figure] that’s being saved end with “.png”.
