Where are the "Training" and "Data" tabs and output layers in Deep Network Designer in R2024a?

After upgrading MATLAB to R2024a, I encountered issues with the Deep Network Designer app.

Specifically, the "Data" and "Training" tabs were missing, leaving only the "Designer" tab visible.

Additionally, the Layer Library only displayed three output layers, lacking output layers such as the "regressionLayer" that were present in R2023b.

Is this expected behaviour?

In R2024a, Deep Network Designer updated to use "dlnetwork" objects by default.

This version of Deep Network Designer does not include training and therefore the "Training" and "Data" tabs are not present

Additionally, "dlnetwork" objects do not require an output layer and therefore, output layers are not in the layer library.

All of the differences between the two versions are in the following documentation page:

Using "dlnetwork" objects from "trainnet" is recommended from R2024a onwards however, if it is not possible to transition to "dlnetwork" as recommended, you can still use the "DAGNetwork"/"SeriesNetwork" version of the app with the "-v1" flag as documented here: https://www.mathworks.com/help/releases/R2024a/deeplearning/ref/deepnetworkdesigner-app.html#mw_c01f379c-a044-4c49-a2c1-13b71e3b15dd
