Describe your feature request

When I run ray up or call create_or_update_cluster(...), the terminal is filled up with output from either rsync (from file_mounts, etc) or any commands i put in setup_commands. These can get pretty spammy.

It would be nice to be able to suppress these unless v

Is there a way to train a bidirectional RNN (like LSTM or GRU) on trax nowadays?

Use case

Polyaxon tracking can be used to automatically log all information generated by Ludwig.

We should probably think about adding support for Polyaxon's tracking module in Ludwig contrib.

Describe the bug
I found that some names agruments in framework aren't consistent.
So for example:

class SupervisedRunner(Runner):
    """Runner for experiments with supervised model."""

    _experiment_fn: Callable = SupervisedExperiment

    def __init__(
        self,
        model: Model = None,
        device: Device = None,
        input_key: Any = "features", 
      

这里好像有个bug，我是在非源程序的目录下运行代码造成的：
