I guess I can simplify it a little.
Basically there are two scenarios:

on local machine
task = Task.Init(output_uri="...", tags=["tag"])Result: everything works. Remote uri is used, tags are set

on local machine
task = clearml.Task.create(...) clearml.Task.enqueue(task, queue_name=queue)> on remote clearml agent, the same code is called
task = Task.Init(output_uri="...", tags=["tag"])Result: init params are ignored, remote uril is not set, tags are empty

Does it make my problem description clearer? I'm not sure if it's a bug or if I'm missing something.
