OK so if I understand correctly, you can only add metadata to items in the enterprise version.
Just to confirm, the screen shot in the dataops pages here refers to the enterprise version?
None

This is what I get when running the exact same training session without clearml

John, regarding documentation - what is mainly missing is how he dataframe / numpy / dict is structures. Yes, an example would be helpful

A bar graph takes a set of numbers and assigns a bar to each number where the height of the bar represents the number. This is what you see in the example in the link I attached.
A histogram takes a set of number and divides them into bins, and plots the number of samples in each bin.

I disagree that the difference is minute 🙂 They are fundamentally different plots. The term used by clearml is misleading.
I will use the manual plotting feature with matplotlib

Thanks John. But does the metadata relate to the entire dataset or individual elements in the dataset?
For example, lets say I have a dataset of images, and I would like to attach metadata to each image - e.g. a "type" field which could have values 1,2,3,4,5...
How would the dataframe be constructed? I assume one column would contain an ID identifying the image, and the other column would be "type". If this is the case, what would the ID be?

The code that generates this is the fit method in TF
model.fit(train_dataset, validation_data=val_dataset, epochs=cfg.fit.epochs, callbacks=callbacks, verbose=2)

Clearml is activated in the usual way:
task = Task.init(project_name=project_name, task_name=name, output_uri=True, auto_connect_frameworks={'tensorflow': False}, **kwargs)

The project is many 1000s of lines long. It fails in the model.fit TF command. The only thing different from other versions which work is the loss function - which I share below. The relevant class is BoundaryWithCategoricalDiceLoss which is called with boundary_loss_type = "GRAD" . When I use the loss with boundary_loss_type = "MSE" all works fine. This class is a subclass of CategoricalDiceLoss which is a sub-class of keras.losses.Loss

The only difference between the two runs is that in one run project_name is and empty string (in which case all is OK), and in the other case project_name has a value
