[BUG] Alias for model version doesn't show up in the table

[elvira-salakhova-r]

Willingness to contribute

No. I cannot contribute a bug fix at this time.

MLflow version

2.9.2

System information

• OS Platform and Distribution (e.g., Linux Ubuntu 16.04): Debian GNU/Linux 10 (buster)
• Python version: 3.9.18

Describe the problem

Inside the Models section when a certain model is selected there is a pivot table with model versions, their tags and aliases. After assigning an alias via button "Add" from UI or from code using client.set_registered_model_alias method, the alias doesn't show up in the pivot table.

When I click the button "Add" for the model version I've just assigned the alias, the alias becomes visible in search panel as if it was actually assigned. The method client.get_model_version_by_alias also return the correct alias.

So, the problem is that column "Aliases" won't display any aliases even if they are set.

The expected behavior is the following: after setting an alias it should be displayed in the pivot table similarly to the "Tags" column.

Thanks, this is definitely a UI bug. We'll look into fixing it. cc @hubertzub-db

@elvira-salakhova-r I couldn't reproduce the bug on v2.9.2 nor on the latest version (videos attached). Can you confirm the bug still persists on the latest version from master branch, i.e. v2.10.1? If true: is it possible for you to record the screen while having browser developer tools -> "Network" tab open?

@hubertzub-db Maybe its due the used storage backend? I saw an issue here about File-Based storages having no problems with serving aliases, but database may dont fill them due performance reasons: https://github.com/mlflow/mlflow/issues/9783

I can confirm that I also run into the same issue when using a PostgreSQL storage backend. With it the alias tag is not shown like @elvira-salakhova-r mentioned here.

@ippen thanks a lot! @jerrylian-db @smurching can you take a look at this one? It seems that aliases API is breaking when database backend is being used

Thanks for flagging, I'll take a look at this & options for a fix
