Subject: Clarification on RT2 model output structure and usage

Hi [Support Team/RT2 Developers],

I’m working on integrating the RT2 model into a ROS2-based robotic arm control system. The model is being used to generate control commands based on visual input (images) and natural language instructions. However, I’m encountering some challenges in understanding the structure and purpose of the model's output.

Here’s what I observe:

1. The model output is a tuple with two elements.
2. The first element is a tensor with shape [1, 1023, 20000].
3. The meaning and intended use of this tensor are unclear in my application, as the size seems too large for direct use as robotic arm joint control commands.
4. The second element in the tuple has not been explored yet.

Could you please clarify the following:

1. What is the meaning of each element in the model’s output tuple?
2. Is the first tensor (shape [1, 1023, 20000]) designed for use in robotic control, or does it require additional decoding or processing? If so, what is the recommended approach?
3. If the second element of the tuple is relevant to robotic control, could you provide guidance or examples on how to interpret and use it?

Any examples, documentation, or best practices related to using RT2 for robotic arm control would be greatly appreciated.

Thank you for your assistance!

Best regards
